-
- I developed a roll of Tmax 3200 for the first time, and it came out fogged.
-
- I can see four possible reasons for this:
-
- 1. The file was fogged because of the way it was handled before I got it.
- I purchaesed it a few weeks ago, and has since kept it in my fridge.
- Expiration month was this month.
-
- 2. It was fogged because of the way I handled it. I didn't expose the film
- can to more than ordinary room light. I loaded the developing tank
- in my bathroom where I could barely see light in the door chinks after
- half a minute in the dark, but I did everything under a towel. The whole
- film is evenly fogged so this alternative seems unlikely.
-
- 3. I messed up when I developed it. I did exactly what I use to do when
- developing Tmax 100 (but developed for 9.5 minutes +-3 seconds) in Tmax
- developer, when I always have got consistent results. So this alternative
- doesn't seem likely either.
-
- 4. It is supposed to be like this. The fogg is definitely there, with
- clear grain structure all the way to the edge of the film, and the
- same over the whole film. I didn't notice it at first, but when I
- make a contact copy of a frame with an unexposed piece of the
- fogged (developed) film covering it, I need 300% more light (2
- f-stops). When I try this with a piece of unexposed Tmax 100 I
- need 50% more light. Even if you push a film this far I can't see
- a technical reason why you should not be able to clear the film
- where it is not exposed, so I don't think this is a likely cause
- either.
-
-
- To me, the most likely cause seems to be number 1, the film has aged to
- fast. Does this happen, or did I do something wrong?
