11/13/2023 0 Comments Vuescan batch scanProfiling your scanner is a process that I would say is essential: In my case, I run scans with and without this scanner profiling, and for my scanner, there was a noticeable color difference. The ICC profile will be saved to the file name you specified Choose Profile | Profile scanner from the drop-down menuĩ. You may need to readjust the target on the scanner platen and press the Preview button again if the image is at an angleĨ. Adjust size of the VueScan cropping mask until it matches the IT8 target imageħ. If necessary, rotate the preview image so that the gray scale is at the bottom and the letters and numbers can be read normallyĦ. Click next to Color | Scanner ICC profile and choose where you want to write the ICC profileĥ. Click next to Color | Scanner IT8 data and choose the IT8 description file that came with your IT8 targetģ. To profile your scanner or digital camera with an IT8 target*:Ģ. It is an easy, quick process, which takes much longer to write and read about than to execute. (You may want to save the original default file for later comparison to your calibrated file.) You only need to calibrate the scanner once, regardless of what films you scan subsequently. VueScan will offer to store the profile in its default scanner.ini file and it is easiest to do just that, although you can select your own scanner profile file name and storage location. Once the reference slide is aligned properly, and you have guided VueScan to where you stored the color data reference file, you can select Profiling/Profile Scanner, and that is it. This is obtainable from the Silverfast website the easiest is to type the reference number on the slide into Google and it will find it for you. You also need the reference file that corresponds to your particular AT-8 reference slide VueScan will ask for this. This involves loading so-called AT-8 reference slides, obtainable among other from Scandig or SilverFast (listed in the references at the end of Part 1 of the article). The actual process is described on the VueScan website, quoted in the text box below. Since each scanner has color interpretation biases, due to hardware deviations such as changes in lighting with the age of lights, this is a calibration that needs to be done with each scanner individually. It is the process to calibrate the scanner so that scanned images correspond to an absolute, objective color representation in a consistent manner. VueScan calls the color calibration of the scanner “Profiling”. “In all cases, turn on the scanner before opening VueScan, otherwise the program does not acknowledge the scanner being present.” Scanner profiling I next deal with scanner calibration, slide film calibration, and negative film calibration separately. This ensures that scans reproduce color in a consistent and correct manner. The key to achieving this lies in the initial color calibration of the scanner and films, described below. In simple terms, most of the slides and negatives need to be perfect, or nearly so, without additional, individual color (or other) correction. Whilst digital color reproduction is probably the key issue, with layers of complexity behind it, an absolutely critical part of the solution for this is to have each scan as good as possible without needing post-scan processing. Setting upĪs highlighted in Part 1, a key issue in bulk scanning is to get consistently good digital color reproduction of the original images, with as little intervention as possible. And the key to getting these color settings right lies in calibrating and setting up your scanner for different films. THE key to bulk scanning is to get very close to good color reproduction without resorting to individual frame adjustments in post scanning. In Part 2 I look at the detailed scanning setting for color slides, color negative and black and white films, as well as the scanning set-up. The first part described the problems associated with scanning large numbers of analog images, and how these tools, along with the lowered cost of disk space make it possible to digitally archive large numbers of images. This is the second part of a two-part article on bulk scanning slides and negatives using a Nikon Coolscan and VueScan software.
