Hi Vicky, I have not bleached my FP100C negatives for a while (maybe because I haven´t shot 100c for a while..) but I remember couple of things. If your negative is fully workable, meaning that there is a lot of info in it (because you shot one or two steps underexposed) there there is no problem getting a ¨true¨color rendition, still you will have to play with levels in the scanning preview, and you will see that the color temperature varies a lot. I attach the room shot with Elena which looks normal. If your negative does not have lots of info then you will not be able to obtain a full color rendition but only yellowish to greenish results, not matter how much you play with it, that would be my second shots with the palm trees.
So, I would say that playing with level helps, and also sometimes applying color correction too
PD But to be honest I think the second shot tones were due to the fact that I could not match the correct colour..
