Hello Bob,


The issue is the overall "purple" colouration of the neagtive, when this is inverted to a positive there is a strong yellow colouration, like a yellow filter was used.  Note the frame on the left does not show this colouration and it inverts to a normal looking print.  Comparing to C-41 images I have taken they look more brownish to my eye, and so are similar to the left most frame.

OK, FOLKS,

All I see is the standard color mask (mentioned in previous post) that all color negs have to allow printing without excessive filter packs.I see NOTHING out of the ordinary.Am I missing something???

CHEERS!

Took a quick picture of part of a strip on the light box

The left most image has normal colour, the middle one has a strong yellow effect, and the right one the effect is present, but much less severe.

Hope this helps shed some light on the issue.
