TMax 100 shot at 400

[JeremyLangford]

How long should I develop Tmax 100 accidently shot at 400 in D-76 1:1 dilution at room temperature? Is there any way I could develop this with another roll of Tr-X 400 shot at 400 in the same developing tank? I have these two rolls that I need to develop in class in about 10 minutes and I'm thinking about just developing them together for 10 minutes.

go to the massive developer chart at digitaltruth.com

or just use rodinal and stand developing (1:100, 1 1/2 hr, no agitation).

What is room temperature? Remember, time and temperature are dependant. Find out what room temperature is and then go to the M.D.C.

Just a hunch, but I say "No Way" to the Tmax 100 & Tri-X in the same tank.

Jeremy, I hope you are getting all of these little Uh-Ohs out of your system this semester. More than 10 minutes warning for serious answers would be appreciated.

Grinning. Good luck!

Well my teacher didn't even show up so it didn't matter that I didn't get an answer in 10 minutes. I have checked the M.D.C. and they don't have anything for TMax 100 shot at 400 in D-76 1:1.

Tmax100 in D-76 1+1 takes longer to develop than Tri-X at 400, so I don't think it would be worth putting them together. You could just try the Tmax100 for 18 minutes at 68F (based on 12 minutes @68F for 100 EI, times 1.5 for pushing two stops to 400 EI.)

Underexposing the film two stops isn't that big a screw-up. It's not ideal, but you can get usable images from it. Call it an experiment.

BTW, temp is kind of important here. It affects the speed at which the chemicals work. You can't just expect "room temperature" to always be the same, and variations of a few degrees have a big impact on the film.

After looking at the M.D.C. website more more intently, I found that the links on the side can answer all the questions I have with directions for push processing (There are even special directions for push processing TMax films which is what I'm doing) and temperature conversion. Now I will have a great starting point for developing my Kodak films in D:76 1:1 and I am going to start taking the temperature of the developer before I start developing from now on.

Temperature conversion: You didn't download and print the Ilford Time-Temp chart I told you about months ago?

'Bout time you realized that knowing the temperature of the developer is important.

You don't need to be a Techno-Geek when it comes to developing B&W film. Consistent & repeatable results will do.
