![]() I am not a scientist and I don´t want to claim anything, but decide yourself, which of the scans you prefer most: the one with the custom profile or the default Epson profile. This has nothing to do with calibrating the process from scene to final scan. But with the manufacturer variation in mind, I think it can be helpful to make a color profile for positives that ensure correct replication of the underlying linear scan before inversion. I know that a common concept says that there is no way to profile scanners for color negative film. This has improved my results dramatically. I also use a custom made scanner profile together with Epson Scans. Digital ICE increases scanning times significantly and the algorithms are not as good as in Silverfast´s iSRD technology. While Epson Scan is a good piece of software and it does not have to be purchased separately, I also lacks a certain ability to render fine details, especially when used with digital ICE. Nevertheless I want to point out some drawbacks of "Epson Scan". The whole idea of the tutorial was to provide you with a solid workflow to get good results from you Epson scanner. I have been told that these additional casts are due to a phenomena called "registration issue" and has to do with the overall precision and calibration of the scanner. However I often encounter additional color shifts after the final scan has been made. Note: If you feel this step counterintuitive you always have the option to finalize all color corrections in Epson Scan using the "Image Adjustment" panel. The biggest problem is that "RED" and "CYAN" casts needs to be either eliminated by a combination of the "TEMP" and "TINT" slider or by using the color curves in the "TONE CURVE" section.The TINT slider is for a "GREEN" respectively "MAGENTA" cast.Bt with some experience you will learn how to use this slider to get perfectly neutral scans. This slider is originally for setting the white balance of digital raw files and not perfectly suitable for color correcting a scan. Use the TEMP slider to compensate for either a cool or warm cast.I will address some basic tips for color correction in an upcoming post. Color correction is a difficult task and often the biggest problem for good scanning results. Try to increase the gray area below the histogram to neutralize color shifts. When color correcting in Lightroom the histogram is a wonderful guide. However, avoid drastic changes as this might destroy the film character of the scan. Another benefit from using Lighroom for post-processing. Highlight or shadow recovery might be required. After the contrast curve has been applied we might need to adjust the tonal values in the basic panel.
