I understand that the assignment of colours to the greyscale images is carried out by the original software/hardware engineers. The mosaic of RGB 'tiles' that is over the chip is only made up of weak RGB filters. In the necessary process of amplifying and interpolating the colour information , subjective decisions are made as to how to describe the final output. In some instances a more 'pleasing' rendition can be chosen at the expense of accuracy ( in much the same way as Epson inkjets can produce oversaturated images when not individually profiled ). In theory any preprogrammed innaccuracies can be modified by profiles , but any these innaccuracies will obviously not give us the best starting point to work from. A more linear output from the chip would help if you wanted to make your own profiles ( however there are still issues on how the film curve applied to the raw files affects profiles). > >I am finding that I have persistent problem colours (cyans and pinks, >saturated reds) which in my chosen working space >(adobe 98) are way off.

I think that the jury is still out on just how Sinar are managing their colour at present.And reds are a particularly difficult area on most cameras ....including film!. Would any lurking camera manufacturers or distributors like to comment ?
