hi, could anyone explain to me what the effect of extending the colour developer stage of E6 processing? I'm sure I've heard people mention before that they use 6 minutes instead of the recommended 4 minutes suggested by Kodak of yes, I'm referring to the Kodak 6 bath kit here.

Whilst I'm very happy with the results I'm getting with my Kodak E6 results it would be nice to know what's going on with this stage I've been using 4mins 30 secs for colour dev (although why this is I can't really remember!)
