Hello everyone!
I bought an ADOX CMS 25 (a replacement for TP 2415) for testing purposes and have developed it. The negatives look fine so far, but I haven’t scanned them yet. Now I have a few questions:
1.) Are there any temperature/time curves available anywhere? The technical specifications only provide data for 20 degrees. I ended up developing the film at 24 degrees (all my chemicals are at this temperature and I don’t want to cool them down) for 5 minutes (25 ASA).
2.) The film is slightly grey. Is that normal?
3.) The exposed leading edge of the film isn’t completely black; you can still ‘see through’ it. Is that correct?
Many thanks for your experiences and opinions!
Regards

1.) No idea.
2.) I’m looking at my negatives right now. They’re almost completely clear.
3.) Yes, I can see right through my negatives at the start of the roll. This film is probably quite delicate and just doesn’t offer much density. You notice that when printing too: there isn’t much contrast headroom to play with. Otherwise, though, I think it’s a great film. Are you happy with your pictures?
Best regards,
Samuli

OK!

So it’s okay...

Yes and no...
The sharpness is great, the grey tones are okay too, and the shadow detail is good. But I’ve got a scratch across a few negatives, even though I developed the film very carefully and didn’t strip it (to dry). Strange...
But now comes the big problem:
There are lots of white (!!!), irregular spots on the negatives. Some of them are very large. And I don’t know what they are or where they’re coming from... :-((( They look too irregular and, in some cases, too big to be pinholes.
I’ve had this problem before with another documentary film (Gigabitfilm) and didn’t find a solution there either. I’ll start another thread about that, though.
Do you have any ideas?
At least I now know that you can remove spots from the film very effectively in Photoshop...

I’ve no idea. Are the spots white on the negative (= completely transparent) or white on the positive (= completely opaque)? In the first case, it could just be dust inside the camera. It’s happened to me before. Very annoying. In the second case, something must have stuck to the negative during the process.
I don’t have any on the negatives I’ve got with me right now. But from the first test run, I remember that the emulsion is very sensitive to all sorts of interference: I had scratches, dust, etc. on it. (The emulsion seems to be very sensitive to that sort of thing.) On the second attempt, I took particular care to ensure a clean process and developed the film in stages, and the result was flawless. The instructions stated that you absolutely must use an acid stop bath – stopping with water is not enough. I don’t know if there’s any connection, but my negatives were cleaner when I used an acid stop bath.

White on the negative...

I don’t think so; there are too many for that. And I don’t get that many spots on other films.
I always stop...
