Thus, the color here is a bit off, but the detail is extraordinary. The scanner shows excellent tonal range, color purity, and saturation. The very darkest swatches of the gray scale are plugged below about step 20, but differentiation in the highlights is excellent. Different brands and even different products within the same brand vary wildly. You should be able to match most films with one of the standard setups, although as noted above, odd films like Kodak Royal Gold 25 are problematic.
Colors are very saturated, and there's a slight yellowish cast overall.
Tonal range is very good, extending from extreme highlights to deep shadows, although the reddish cast is more pronounced in the darkest areas. Nonetheless, this will give a fair indication of maximum performance with the upper end of typical film emulsions. Gold 100 target. Visual resolution along the horizontal axis of the film extends to 1300 line pairs per picture height or so, a very impressive number. As a result, the USAF target will yield much more conservative numbers.
