I'm not sure but if I remember correctly the Kodak BW400 film (= B&W film for C-41) has also a brown base?? I'm not sure but can't check it right now.
You could develop an unexposed part of the film to see what colour the base is in itself.

The BW400 is C-41 so it has an orange mask for printing as do all color C-41, this is not the same thing, all transparencies are clear.

AgX said it correctly, I just find it weird the yellow silver turns red when it dries...

AgX can I bleach it even now or is it too late now that it's been exposed to light?

Stone, you already developed the CLS layer when you developed the film. The developer doesn't choose. You can bleach it at anytime, just watch how much you bleach it because you don't want to be bleaching the rest of the image silver out.

Actually, the CLS layer doesn't need to be developed - it's colloidal silver particles (very small) that's used as a yellow filter and normally is bleach/fixed out of the film during Kodachrome processing.

So far no-one aside of me referred to that difference in min density/colour over the width of the film.

Haha I haven't had time to mess with them again or attempt a bleach as mentioned. I'll see if I can get to it before I leave for a Acadia this Friday (with my4x5!!)

I would be pleased if someone just could explain that uneven effect you got so far. Maybe I just missed something.

Well I don't know why it goes red when dry and lightens to yellow when wet... It is very strange.

Seemingly I missed something indeef...
So, that uneven spread of colour over the whole film width (see post #1) changes whilst drying?

Yes I believe so.
