For all current scanner models, is avaliable in our Filmscanner-Shop.SilverFast is the worldwide leading software for film scanners and flatbed scanners. Almost every scanner, even those which have disappeared from the market a long time ago, can be operated with SilverFast. On this page, we have collected numerous questions and answers related to the scan-software SilverFast of the German company LaserSoft Imaging. Please consider that in our there is also a special area for the scan software SilverFast. LaserSoft Imaging are available in our filmscanner shop.Finally, at the beginning of the year 2009, LaserSoft Imaging introduced a Kodachrome IT8-target into the market at a reasonable price, so that an IT-8 colour calibration can be accomplished specially for the Kodachrome-films. As described in the following text under the title, within the SilverFast scnsoftware, it is possible to create different IT-8 profiles and choose them by a simple mouse click.Since March 2012 we also offer a Kodachrome-Target produced by Kodak. It is a bit cheaper than the LasersoftImaging one but you need a third supplier software to calibrate the scanner.
We offer further informations about Kodachrome slides on our KnowHow site. How is it possible to recognize the type of film of an IT-8 target?There are different film types and sizes of LaserSoft Imaging for the. While the size can be simply measured or estimated, the type of film is only recognizable by thorough observation of the target.On a LaserSoft Imaging IT-8 target in a framed slide (35-mm film), the type of film is readable on a vertical text line at the right edge of the target, for example as in the adjacent picture 'Printed on Kodak Ektachrome Professional Film'. The text is hardly decipherable to the pure eye; but by observing the slides with a magnifier or after a high resolution scan, the vertical text is easy to read. In case of a non-transparent target of LaserSoft Imaging, the type of film at the right bottom are clearly readable, as you can see in the example of the second image the text 'Printed on Kodak Professional Digital'. These images are zoomed cutouts of a scan of the respective IT-8 target. How long does an IT-8 target keep its original quality?An IT-8 calibration target is a high quality piece of film material in the field of transparencies that contains certain standard colors on a certain film (for example Kodak or Fuji).
Like at all other photographic films, an IT-8 target also ages and loses its color fidelity. How long is it possible to use an IT-8 Target?Those who keep their photographic films in a cold, dry and dark place can still enjoy also after 10-20 years best colors like the way they were right after the development of the film. Of course, the same also applies for an IT-8 target if it is kept in a cool, dry and dark place. Due to this reason, a target should never be simply left on the desk or on the scanner. If it is exposed to the sun or to heat as for example from the screen, it will ages quickly and will lose its reference colors.
The result is a defective scanner calibration; the respective defective colors are transferred to each of the scanned images.An IT-8 target should be kept in a cold, dry and dark place. How are the profiles of different IT-8 targets handled?If one wants to create some own ICC profiles for different types of film, the respective target must not be scanned each time. Instead, an own profile can be create for each target and it can be activated when it´s needed. The procedure for this is as follows:First, the function Own ICC-Profile Name must be activated in the Auto-Tab of the option dialogueBy clicking on the calibration button, one can create a name for it after the completion.
Thereby, one can also include the date and the type of film in the file name.Now, by opening the CMS-tab of the option dialogue (see adjacent image), one can see that the just created profile has been selected as the input profile. If one wants to create another profile with a target of a different type of film, the calibration procedure has to be repeated with the new target. Then, one assigns the respective name to the new profile. This profile is now automatically selected as the input profile.In the CMS-Tab of the option-dialogue, one can now switch between the different profiles and thereby choose the matching one to the respective film material. This procedure can be repeated as many times as wanted, so that an unlimited number of different input profiles can be created. Why does the IT-8 calibration not provide a noticeable quality increase?From time to time, some of our clients complain that the IT-8 colour calibration does not provide a significant increase of quality in the scans. Also in our forum, the owners of the same scanner model discuss whether the calibration and profiling of the scanner does make sense or not.
In one case, the IT8-calibration really made wonders, in the other case, the owner of the scanner barely notices any difference. How are such different statements possible? Is the quality increase only a subjective perception of can an objective statement be given about that?Every technical device is subject to certain quality fluctuations and works in a firmly defined area of tolerance. Example: in the case of a scales, the producer indicates that, for example, it measures a weight of 100 kg with a tolerance of +- 2 kg. If now 3 persons buy a model of this scales and weigh a block of 100kg, the first will for example get a weight of 98kg, the second maybe 102 kg and the third possibly exactly 100 kg.
If those 3 buyers let their scales to be calibrated (gauging)at the board of weights and measures, then, after the gauging, all 3 buyers will get a uniform weight of 100 kg by weighing the block. The first and the third buyer will say that the fee of 50 € for gauging fully was the money worth; but the second will say that the gauging did not make much sense as it only cost money. By this way, every buyer evaluates individually the sense and benefit of a gauging with costs at the board of weights and measures. But after the calibration, all 3 of them have the guarantee that their scales works in the right way.What I mentioned in the above example also applies for a scanner: every filscanner works within a certain area of tolerance; in case of one modell the colours strongly differ from the natural colours, the other model's colours correspond very well to the original ones.
An IT-8 colour calibration effects that the scanner is set to a clearly defined quality level, no matter if the level was high or low before the calibration. Thus, after the colour calibration one can be sure that the scanner provides real and natural colours.Conclusion: the IT-8 profiling provides a high quality level to the scanner concerning the colours and the colour fidelity.
But the actual need of correction differs from scanner to scanner and changes in the course of the time.In order to come back to the initial questions: thus, a user complaining that the IT-8 calibration did not change much got a good device from the production by which not much corrections were necessary. But as a scanner changes its features in the course of its lifetime, the calibration may not show some effective results until a period of 3 months. And the different users who report in a forum of the sense and benefit of the IT8-calibration of their device are, of course, all right concerning the results in exactly one scanner. In one case, a large correction was needed, in the other case only a small one. But the results of a subjective evaluation do not apply generally on a type of device. For this, a statistic of umpteen or even hundreds of subjective evaluations were necessary. IT-8 calibration with advanced IT-8 TargetsIn the year 2018 Lasersoft Imaging brought a new target series on to the market.
The so-called advanced targets are based on the new standard ISO 12641 part 2. What are advanced IT-8 targets?When in the year 1993 the IT-8 standard was published in the ISO 12641 the structure of transparency targets (IT8.7/1) and reflective targets (IT8.7/2) was defined.
According to this standard in the years 1993 up to 2018 transparency scanners and reflective scanners were calibrated with suitable targets. This 'old' standard continues to apply in the ISO 12641 as part 1, also noted as ISO 12641-1.It took time until the year 2018, when finally a nes standard for the IT-8 colour calibration was defined in the ISO 12641-2.
This new standard, also denoted as ISO 12641 Part 2, is based on new targets, which are designated by advanced targets.The 'old' targets according to 12641-1 consisted of 22x12 colour fields, i.e. 264 colour fields in total, as well as a grey scale with 24 fields; so in total 288 measurement fields. The advanced targets according to ISO 12641-2 consist of 864 colour fields. Thus at the scanner calibration more colour fields are measured and compared with reference values, so that less colour values have to be interpolated and an exacter calibration is possible.Advanced IT-8 targets are available both for scanners with transparency unit (IT8.7/1) and for scanners for reflective originals (IT8.7/2).
On the reflective targets and the larger transparent targets the 864 colour fields are arranged in 36 coloums and 24 lines. On the 35mm transparency target the film area with 36x24mm is too small for 864 colour fields, so that these colour patches are split on 3 targets.Furthermore on all advanced targets there is a bar code with which SilverFast can automatically find the nomber of the appropriate reference file. This feature is well-known from the 'old' target series. At the bottom of the left side of the target there is the manufacturing date. Which film types are available at the advanced targets?There are both advanced transparency targets (standard IT8.7/1) and advanced reflective targets (standard IT8.7/2). The transparency targets in the sizes 35mm, medium format 6x7 mm and large format 4x5' are made on Fuji Provia 100F film.
The reflective targets in the sizes 10x15cm, 13x18cm (5x7') as well as full format targets in the size 15x22cm are made with Kodak Professional Endura paper. In our online shop from Lasersoft Imaging are available.At the 'old' target series according to ISO 12641-1 there were different film types both for transparent targets and reflective targets. In the transparency area one could choose between Kodak, Fuji and Kodachrome films, in the reflective area one could choose between Kodak and Fuji. This selection possibility is not given any more for advanced targets according to ISO 12641-2. Thus a film typical calibration is not possible any more.
And this will not change in the future, since Kodak films and Kodachrome films are not be produced any more. What are the advantages of the advanced IT-8 targets compared to the old IT-8 targets?The 'old' IT-8 targets according to the standard ISO 12641 Part 1 had 288 measurement fields.
During the calibration process all these measurement fields were measured and compared with reference values. For colour tones which were between these measurement fields an interpolation had to be done. The advanced IT-8 targets according to the standard ISO 12641 Part 2 have 864 measurement fields so that less interpolations have to be done. Furthermore these new IT-8 targets have additional colour fields with dark colours and pastel colours. It is clear that a more precise measurement and a more exact colour calibration is possible with more measurement fields.However in practice this more precise exactment of measurements cannot be proven. We have calibrated several scanners with the old part 1 targets and the new part 2 targets and compared the resulting scans. Indeed we could not recognize any improvements of the image quality by using the advanced targets.
Probably the differences and improvements only can be recognizes by precise measurement instruments.Let's have a look at the adjacent picture. If you click on the image a new window opens with an animation of 3 images. First you will se a scan, which is produced by a reflecta ProScan 10T without scanner calibration.
In the second animation picture you will see the scan of the same reflecta ProScan 10T after calibration with a standard target. Finally in the third picture you will se a scan of the same ProScan 10T calibrated with an advanced target. At this animation you can clearly see that the calibration leads to an essential increase of the image quality at this film scanner. However, you hardly can recognize any differences between the scans with the different calibration targets.In practice one does not achieve image quality improvements by using the advanced targets instead of the old IT-8 targets for the scanner calibration.What are the disadvantages of the advanced IT-8 targets compared to the old IT-8 targets?As described in the chapter advanced transparency targets are only available on Fuji film and advanced reflective targets are only available on Kodak paper. At the old part-1 target series one could choose between different film types. If you want to digitize a bunche of Fuji-films you can make a perfect colour calibration with an advanced Fuji IT-8 target.
However, if you intend to scan a series of Kodak slides you will not find a suitable part 2 target. Also if you plan to scan Kodachrome films there is no suitable IT-8 target in the advanced target series.Of course you can calibrate your scanner with a Fuji film target and scan Kodak films. However, a Fuji IT-8 target includes the characteristic film properties of a Fuji film and does not reflect the film properties of other films. If you intend to digitize Kodak films or Kodachrome slides you better use old IT-8 targets as long as Kodak targets and Kodachrome targets are still available. In the reflective area the film type is not decisive.
Which SilverFast version is neccessary in order to user advanced IT-8 targets?The Die Advanced Color Calibration Targets for a scanner calibration is available starting with the version 8.8.0r11 in SilverFast Ai Studio or in the SilverFast Archive Suite. Older SilverFast versions only can handle 'old' IT-8 targets according to ISO 12641 Part 1 and create a colour profile. Where das SilverFast Ai know from if a standard target or an advanced target is used for calibration?Since the version 8.8.0r11 SilverFast Ai Studio can do an IT-8 colour calibration with advanced targets according to the standard ISO 12641 Part 2. A colour calibration with standard targets according to ISO 12641 Part 1 is possibly anyway. If you click on the IT-8 calibration button since the version 8.8.0r11 a selection field opens for choosing the standard calibration with old targets according to ISO 12641 Part 1 or the advanced calibration with advanced targets according to ISO 12641 Part 2. In the 35mm area the advanced calibration is denoted with Advanced 3-slide calibration, since the 864 measurement fields are split on three 35mm targets and so 3 IT-8 targets have to be scanned.
Why is indicated after the calibration that less colour fields have been used?The Advanced Color Calibration Targets have 864 measurement fields in total. In practice not always all these colour fields can be used for the measurement. For examplare due to dust on the target or inside the scanner it might happen that some colour fields have to be omitted during the calibration process in order not to produce wrong colour values for the resulting profile.
However doing without some colour fields still enables an exacter colour calibration than using faulty measurement values to to dust.An additional factor for the nomber of used measurement fields is the colour space. It might happen that some singular measured colour tones are outside of the used working colour space. In this case these measurement fields will not be considered for the resulting ICC profile. Even if some colour fields are not used there are much more than 800 measuremtn fields left for creating an exact ICC profile. What is the Delta E value?When the IT-8 calibration is done successfully the Delta E value us shown.
The Delta E value gives the medium aberration, i.e. The average aberration of the measured values from the expected values of the reference file. In most cases the Delta-E value lies between 0,8 and 1,8. However, if a value of 3.0 is given, this can be considered as normal. The ICC profile includes the deviation from the reference file so that the colours of the original will be displayed correctly.
Dust and Scratches Corrector SRD, iSRD, ICE Is the dust and scratches remover SRD of SilverFast equal to ICE?The most renowed is the corrector of dust and scratches based on the hardware Digital ICE. SilverFast offers a dust and scratches corrector named SRD that is based on the software.
How does this procedure come off compared to the ICE? Can it be used in the batch modus?First, the essential difference between both proceedings should be mentioned: ICE is a proceeding based on the hardware; with an infrared light resource, the original is scanned for detecting eventual irregularities so that dust grains and scratches are detected. This error spots can be then corrected afterwards by the software. Thus, the Digital ICE works by pushing a button, which means there is a status of switched on and off. Due to the additionally necessary infrared light resource, it can be only applied in those scanners that are already structured for ICE, in this concern you can also see our page.SRD of SilverFast is a purely software algorithm.
Those image spots where the dust and scratches have to be applied are to be selected and a degree of strength must be adjusted. After that, a sophisticated algorithm of computation is started that recognizes the spots on the image and retouches them. Thus, while the ICE recognizes the dust particles on the basis of the hardware, the SRD is based on an image recognition algorithm that of course cannot distinguish if a small spot is a bird or a dust grain.
But ICE can recognize this difference, as a bird corresponds to some image spots, but a dust grain forms a slight raise on the film material.Thus, ICE can be switched on per mouse click while SRD must be laboriously individully applied on each image area. The selection of all spots on the image where SRD should be applied can easily take half an hour. Timewise, there is no difference between both functions, as ICE more than doubles the scanning time and SRD needs a lot of computation time in the image processing. Thus, the main difference is that ICE runs fully automatically and that it is based on the hardware, while SRD must be manually applied for each image individually, that is, for each image there is an additional work of up to half an hour. ICE can be simply switched to the batch modus, while SRD does not automatically remove the dust spots in each image in the batch modus.ICE is a correcting function based on the hardware that is activated by pushing a button. SRD is an effective algorithm for the image processing, but it requires a time consuming selection of the spots to be processed for each image.SDR is without doubt an excellent image processing function. But it does not reach the performance, effectiveness and easy handling of the ICE dust and scratches corrector.
What is the difference between SRD and iSRD? The dust removal?SilverFast supports different methods of the dust and scratches removal in different versions depending on the device. The simple method is called, the better method is called iSRD. Where is the difference? To make it short, SRD is based on the software while iSRD runs based on the hardware and the software.SRD is a pure software function that must be manually controlled: on the preview image, one selects the dust grains individually and the software corrects these dark spots based in the image information around them. SRD does not work automatically for a complete image but only for individual spots that are manually entered.
As one has to make the selection manually for each image, SRD is an extremely time consuming matter and not suitable at all for mass scannings.iSRD is a dust and scratch removal function that is additionally based on the software by using the infrared channel of the scanner for the detection of dust grains and scratches. Thus, iSRD works exactly like the funtion ICE (see our page about ).
Contrary to SRD, iSRD works automatically; thus one does not have to select dust grains individually but simply switches on the function and leaves the detection of dust grains and scratches on the image to the infrared ray of the scanner. ISRD works very reliable nd increases the image quality significantly.
Due to the procedure, the scanning speed is reduced by half but no personal working time is required.At SilverFast 8 there are some new features for example for scanning. You can choose between four differnet kinds of displaying the defects: Mark, Correct, Automatic and Original. You can use these Features to controll the Dust and Scratch Removal easily at the preview. With the modulation 'Detection' you can influence the degree of efficiency of the Dust and Scratch Removal.
This is particularly useful for Kodachrome-Slides because of the oftentimes appearing problem with the Dust and Scratch Removal. This modulation helps to reduce the problem of lost picture details. The Studio Version also offers to use iSRD with layers and masks within the expert dialog.

And the opportunity to influence the detected size of the defects. These features are especially for superior Scanoperator and professionals.
Is there any difference between the dust and scratch correction procedure ICE and iSRD?On our website about different, the automatic dust and scratches remover ICE is described in detail. It is about a very reliable method that was already developed in the beginning of the millenium and that has been implemented into many scanners. In some scanners, there is no ICE but iSRD in the SilverFast-software, although the scanners are actually delivered with ICE. Where is the difference?Both procedures are based on the hardware; they use the infrared ray of the scanner in order to detect the mountains and valleys on a slide or a negative. Thereby, the mountains correspond to dust grains and valleys to scratches. Once the dust grains and scratches are detected, the intelligent algorithms can correct those spots on the image based on the image information around them.
This is why it is called automatic dust and scratches removal.Both proceedings only work if the scanner has, beside the CCD sensor, additionally an infrared sensor that scans the image surface. Thus, both procedures use the hardware of the scanner for the recognition of dust and scratches in order to accomplish then the automatic corrections with the software algorithms. The algorithms are different but of the same value. Both are in-house algorithms of the producer, thus hallmarks and/or patents. According to that, a scanner producer builts an infrared sensor in his scanner. Depending on the software, then either the ICE-procedure or the procedure is applied.
As both procedures are protected, no subsupplier is allowed to use these terms, and this is the reason why there are two terms for the same procedure.ICE and iSRD are two equal procedures for removing dust and scratches that use the infrared ray of the scanner that is based on the hardware for the detection of dust and scratches on the film. They differ in the respective algorithm for the image processing.Normally, the scanner producers offer their scanners with ICE. Therewith it is clear that the scanner has an additional infrared ray scanning that is based on the hardware. In the in-house software of the producer there is a button or a checkbox for the activation of ICE. If the same scanner is operated with the SilverFast-software, the respective button is iSRD that uses the ICE-function of the scanner, that is its infrared ray. Printer Profiling with SilverFast Profiler at Version 6.6 Which conditions are necessary for the printer profiling of SilverFast?At the version 6.6, Silverfast offers optionally the possibility for the printer profiling. Therefore, a special test chart with 1026 colour fields is printed in the printer that will be calibrated and scanned afterwards.
SilverFast compares the colour values provided by the scanner with the target colour values that were printed out and from the computed differences, an ICC-colour profile for the printer is created. If this ICC-profile is from then used for the printer, one gets colourfast printouts.Of course, an important condition is that the scanner with which the printed test chart is scanned is IT-8 calibrated. Only if the scsanner does not produce any colour errors due to the IT8-colour calibration, the scanned original can be used for profiling the printer. Otherwise, the scanner errors are transferred to the printer and one gets falsified print-outs, also in case of the images that do not come out of the scanner.A further condition is that the flat bed scanner must be of high quality. A scanner of bad quality can be also calibrated but despite an IT8-calibration no 100% colour fidelity is achieved. I would consider 'bad scanners' those models below a price of 100 €.The condition for a permanent process of colour management is, beside the scanner calibration and the printer profiling, a calibrated screen. Only when the screen shows real colours, one can also expect images coming from the printer that look like those on the screen.
Is the printer profiling of SilverFast possible with all kinds of printers?LaserSoft Imaging offers the printer calibration as an optional module when one purchases the SilverFast-scansoftware. The profiling of a printer works as follows: first, the test chart is printed out and then it is scanned again with a calibrated scanner. Filmscanners cannot be applied for the calibration of the printer as they cannot digitalize non-transparent originals (a printed sheet of paper).Thus, the printer profiling with the SilverFast-profiler only works with flat bed scanners. Principally, every flat bed scanner can be considered for the printer calibration, but it must be suitable for the IT-8 calibration.
If you want to know if there is a SilverFast IT-8 calibration and printer profiling for your scanner, please contact us per. Can the printer calibration of SilverFast replace a spectral photometer?Asyou can read in our page about, the professional creation of a printer profiling always works as follows: first, a test chart is printed out which colour fields are then measured and compared to the reference colours. In case of professional printer calibration tools, spectral photometers are applied; these are special measurement devices that can measure a colour on a paper.
In case of the SilverFast Printer Calibration, a profilized scanner is employed as colour measurement device instead of a special photometer. Are therewith comparable results obtainable?During the price comparison of the SilverFast-Profiler (below 100 euro) with professional spectralphotometer tools, as for example in our shop the commodity group, one can already guess that such a high surcharge on the price for the special profiling hardware will be reflected in the quality.In fact, our shows that therewith, an acceptable quality increase can be achieved in the printing that is sufficient for many amateurs. Thus, those who already own a flat bed scanner and operated it with the SilverFast-software and calibrates IT8, will get for a reasonable surcharge an additional printer profiling, so that one gets clearly better print outs as if without calibration.
For the professional users who attach a high importante to the colour fidelity, also in the case of the printer or the photo printer, the SilverFast-Profiling is not an alterntive to an extra toolset consisting on spectral photometer and profiling software. Questions about Silverfast HDR (High Dynamic Range) Who needs SilverFast-HDR?Millions of amateur photographers shoot their photographies with some small compact cameras that generate some finished image files in JPG-format that are already optimized in the camera.
Semiprofessionals and professional photographers generate raw files with their digital cameras, of which finished image files are generated with the support of a RAW-converter. Basic camera adjustments as white balance or brightening/dimout can be accomplished afterwards, as one has the raw data available that measures the CCD-sensor of the digital camera. By this way, one can accomplish the important adjustments unhurriedly at home in front of the computer and does not have to care about everything during the shooting. Moreover, certain errors happened during the shooting can be corrected afterwards.What is applied for digicam photographies can be transferred in the same way on the scanned photographies.
Those who digitalize paper photographies or film material with the support of a flat bed scanner or a filmscanner have to do certain adjustments in the scansoftware on the basis of their image files in JPG-format or TIF-format. A wrongly adjusted colour depth, a much too low resolution or a non activated film grain equalization is then firmly set on the image file and cannot be corrected afterwards.With Silverfast it is possible to save the raw files coming from the CCD sensor of the scanner in HDR-format and process them afterwards with SilverFast-HDR. By this way, one gets the same workflow as one does in case of the digicam images: one archives the unprocessed HDR-raw data that contain all the information of the original measured by the CCD-sensor, makes certain adjustments and corrections based on the raw-data and generates therefrom the finished image data.Thus, every photographer who works with its digital camera with raw data is recommended also to work with raw data in the scanning. Also, every ambitioned user who digitalizes his filmmaterial and intents to get the maximum image quality should generate HDR-raw data to in order to leave the possibility open to be able to further optimize the raw material at any time, also if the requirements to the image files are low for the current purpose. Is SilverFast HDR an independent software?With SilverFast HDR it is possible to further process the raw data that were generated during the scanning with SilverFast.
During the HDR-scanning in the SilverFast scan-software some raw data are generated that are independent from the software configurations. These raw data are loaded in SilverFast HDR and some finished imagedata are therefrom generated. Thus, it is possible to accomplish afterwards in SilverFast HDR those configurations as for example the JPG-compression stage, colour adaptations, correction filter, that otherwise are made during the scanning with SilverFast. This is why both procedures of the scanner and the image adaptation can be split in the scan programe, so that they can even be accomplished by different persons at different work stations.SilverFast HDR is a completely independent software that indit processes the raw data generated by the SilverFast-scansoftware, but it is not related to it. Accordingly, SilverFast HDR is also delivered as an independent CD/DVD and has to be installed in a second process. SilverFast HDR also has an own serial number.
Those who buy SilverFast HDR as a bundle with the scansoftware SilverFast can sell SilverFast HDR afterwards again individually. Is it possible to scan with SilverFast-HDR both proceedings and split the image creation?SilverFast HDR is an independent software package that can be purchased and installed independently from the SilverFast scan-software. While the scan programe SilverFast is applied in order to digitalize film originals of non-transparent originals with the help of the scanner in order to generate HDR-raw data, HDR-SilverFast is applied in order to generate some finished image data form the raw data.Both procedures of the HDR-scanning and the image release can either be separated timewise or physically. Thus, it is for example possible to digitalize on one day several hundred slides with the help of a filmscanner and convert them in the following days in HDR to finished JPG-images. It is also possible that in a company, an employee 'only' generates some HDR-scans in a scanning room and that another employee generates therefrom finished image files in another office. Thus, these procedures can be split physically and timewise.We offer within our to digitalize film material and photo material in the HDR-modus.
With the help of the software SilverFast-HDR it is then possible for the client to generate some JPG's and TIFs from generated HDR-files. Then the client does not depend from the configurtions made during the scanning but can practically scan the originals by himself without having an own scanner. Can SilverFast HDR proceed fully automatically?The software SilverFast-HDR is available in different packages. One of the high-end packages contains the automation tool ColorServer, with which it is possible to make a full automatic processing of the raw data. For example, those who have some continuously repeating procedures in the processing of the image data are best served with the Colorserver-expansion.Example: a website creator always needs an exemplar of the scanned originals sized 600x400 pixel with a medium JPG-compression in the sRGB-colour range with a slight contrast optimization. Then, one sets a so-called hotfolder with ColorServer in which exactly those processing steps are accomplished based on the raw data.
Silverfast Software
The hotfolder is a file folder monitored by the Colorserver of SilverFast HDR. As soon as a file is stored in this folder, mo matter if manually or by the Silverfast-scanprograme, SilverFast-HDR automatically starts the desired raw data conversion and generates the desired output-file in a previously defined folder.With SilverFast HDR, as many of such hotfolders as wanted can be arranged. By this way, one can accomplish certain data conversions form raw data fully automatically. What is HDRi 64Bit?The 64Bit HDRi-format (HDRi = High Dynamic Range + infrared Channel) contains the Raw-Data of the Scan and also the information of the infrared channel.
Silverfast 8.8 Review
All information of the dust- and scratch removal are saved within the infrared channel. HDRi-Files contain all data which can be delivered by the scanner. So it is best suited as archival format. Like a normal HDR-File you can edit it afterwards with SilverFast HDR whenever you want.Because of the additional channel, HDRi-Files need noticeably more space than normal HDR-Files. But this should not mind for archiving your pictures because even today there are external hard discs available which have several terabyte of storage capacity.Fo.
