snip A very fair question! The answer is simply that the colours in the print are far more natural than those in my newly digitised slide. For example, in the print the sky contains grey, rainy looking clouds below a pale, whitish background of higher cloud. The digitised slide makes

I am in the fortunate position of having a professionally made print, some 20 years old, from a transparency (Kodachrome) some 40 years old, one of very many! My first attempt with my new slide scanner was on this same slide, and hence I am able to see the colour changes over those past

Looking through the examples I noticed that B and G had a colour cast similar to the colour produced by the filter on colour negatives. Some months ago I spent some time turning colour negatives into a digital form and then processing them in GIMP. Having got the original RAW images I had a look

It would be useful if the slider range could be altered, especially to be able to go below 0.7. I am not a programmer and, therefore, I do not know if this is possible or how complicated it is but, if it can be done, I would love to be able to try the effect. Norman
