Developing Tmax 100 rated 50 with tmax developer

[kad]

Hello all,

I shot some rolls of tmax 100 (35mm) and overexposed most shots by 1 stop (= rated 50).

I never used tmax 100 before, but I overexposed because I used same way of working with tmax 400 and liked it (more shadow detail).

I'm using tmax developer. If I develop my films using the by Kodak recommended time for tmax100 rated at 100, would I be fine (tmax 1:4, 7,5min, 20c/68f)? Or should I adjust development time?

Anyone experience with overexposing tmax 100?

Thanks in advance,
Kristof

Cut back a minute from the development time and you should be fine.

Following the old axiom 'When in doubt overexpose and underdevelop', you could deduct 10% from the time recommended by Kodak. However, exposure and development have a different effect. You can't counterbalance one with the other. Consider a proper test. This one-time effort takes out the guess-work and allows you to concentrate on the image next time, rather than worrying about exposure and development. Trial and error cost more time than a proper test.

For what it's worth, I expose Tmax100 at 64 in D76 1+1 for normal contrast scenes.

T-Max 100 exposed at an Exposure Index of 50 and developed in T-Max developer as Kodak recommends for EI 100 suits my enlarger and printing preferences.

Are you going to scan or enlarge?
if scanning cut the dev time by 10% or so

if enlarging develop as 100

The enlarger can print through the highlights easier than the scanner.

With only one stop more exposure than what the manufacturer recommends for b&W negative film with the characteristics of 100tmax the safest way to handle this situation may be normal development. If your normal development has proven to be generally satisfactory in the past then you might as well finish the job. You may prefer the tonal rendition of the nominal one stop to what you would have gotten if given a stop less exposure. At least you will have some basis for a personal preference.

In the future make at least a quick and dirty test by giving some scenes regular and one stop over exposure and make a good quality straight print of both.

Are you using a good enough system of exposure to determine what normal exposure so be in the first place? What is normal is both objective and subjective in nature and differs by photographer.

Is the normal development well suited for what you photograph? Would a different time or tempeture or agitation method be more to your liking?
The reason I ask these questions is that my impression from reading your query is that you have yet to do your homework.

The lessons learned from doing the homework required can not make a good translation from my house to yours. I would sugesst that if you do not do your homreork that 25 years from now you will still uncertain as to how proceed to achieve a satisfactory end result.

I indeed don't have done testing of films/exposure/development combinations.

Started b&w photography course in september last year, used Tmax 400 all the time (proposed starter film). Through my little experience I have found that overexposing tmax400 1 stop (rating 200) in combination with my camera and developing at the time/temperature proposed for 400 has given me better prints (indeed partly personal taste probably).

When using tmax 100 I copied this process... You are right, I should have first shot a test film at various exposures and see where I got.

Thanks.

I usually rate my Tmax at 80, develop it in Tmax developer 1:7 dilution at 75 degrees F. for 7 minutes if using a condenser enlarger or 10 minutes if using a cold light enlarger. The dilution, time, and temperature was based on a data sheet I got from Kodak quite a number of years ago before the new Tmax films were made. I use a condenser enlarger so I use the 7 minute developement time and have been pleased with the results, of course, YMMV. If you think the highlights might block up then use a 1:9 dilution. Good luck.
