Although your maths is way above my head your results are most
impressive. I have worked with old colour transparencies most of which
are Kodak processed and have been stored in relatively good conditions.
They were copied using an attachment to my digital camera and processed
using UFRaw and Gimp. I will be happy to try your plug-in especially if
it will work with RAW images. Please let me know which is the best to
use JPEG or RAW.
