The profiles do not apply highlight rolloff or faded black point by themselves. We believe that is better accomplished using Lightroom curves to avoid imposing our guesses on you. The included film emulation presets and curves will support you on that aspect.

Clipping is good. We do not forbid it, so you can get help from Lightroom to visualize the blown out areas. Moreover, Lightroom’s built-in highlight handling algorithms is much better than can be accomplished with profiles alone.

We painstakingly calibrated each simulation to maintain middle grey as neutral as possible. For the most part we succeeded, so it is very easy to compare the effect of each profiles on the colors without annoying color casts.

Film saturation come from complex interactions between layers and dye couplers. We did simplify the models of these phenomena, which opened margin for interpretation. Therefore Kodak Gold 200, for example, was intentionally left with lots of saturation, whereas Kodak Portra was left more controlled.

Some profiles are similar to one another, notably Portra 800 and Ultramax 400. This was a bit surprising to us, but we follow the science wherever it takes us. Indeed, take a look at these stocks’ specsheets and compare the sensitometric data: it is surprisingly similar. Combining that with the removal of highlight rolloff and black fade, and our accurate middle grey calibration, we simply made it visually clear that these stocks have more similarities than differences.
