The colours I get from the fp are quite pleasing. I used the Color Checker to make a custom preset. But I think the Merrill colours are better.

My opinion is that using three rather narrow-band filters will give an uneven response across the spectrum, with hues shifted toward the dominant wavelengths of the filters. A Foveon gives wide-band filters with plenty of overlap, so there are two or three numbers for each wavelength.

Ted thinks this gives more noise, which may be true. I can live with a bit more noise if it means better colours.

Are you able to make a custom preset using a Foveon image of the color checker?
