TMAX turning chemicals orange??

[cole]

An odd question, which I'm hoping someone can shed some light on:

I've been developing my own rolls of Neopan for some time now. The other evening, I developed two rolls of TMAX (100 and 400), and when I drained the developer and fix from the dev tank, I noticed both chemicals had taken on a mild orange-ish hue. Both rolls turned out perfect, but I'm wondering if anyone knows why the chemicals would have taken on such a colour cast?

I've never noticed this with any other rolls I've developed. It doesn't seem to be problematic - as I say, both rolls turned out fine. Just a curious event.

Ideas, anyone? 😕

Have a look at the base color of the film and you'll note a color. It is that dye that your chemicals have taken on (usually the developer) and it's harmless.

Can't say I've ever noticed it with T-Max, but it's not uncommon for films to tint the chemistry they're developed in. It tends to be cuased by anti-halation coatings being washed off the film base, and some film/dev combos tint more than others. As spyder2000 says, it's harmless and nothing at all to be worried about.

Thanks very much to both of you. This puts my mind at ease - I thought perhaps my chemicals had expired long before they were due. 🙄

Orange is a new one. I've seen green, blue and purple, and when I pour Rodinal out of a tank developing APX 100, it's the color of a decent claret. As long as the negs look OK, it's not worth worrying about.

These colors are sensitizing and anti-halation dyes. Nothing to worry about.

When I develop 120 rolls of Neopan 400 I presoak them. Super dark blue water comes out when its done, freaked me out the first time!

If I recall the same thing happens to TMax when you presoak it.
