shot tmax400 at 100 please help

[h501c]

I loaded a roll of tmax 400 in my camera and forgot to change the settings. I exposed the whole roll at 100 speed, can it be saved? I have rodinal for a developer is there anything that i can do to get my images to come out?

You overexposed by two stops.

You should under develop by 30 or 40 percent of your normal development time.

Thank you David for your help. I checked the mass chart and it says to develope for 5min at 1+25. i will develope it 3.5 minutes with 2 inversions every 30 seconds, does this sound like a good way? i dont know if this matters but the tmax400 is the new emulision.

Realize though that your negatives will be very low in contrast. Printing them may prove to be a challenge. Expect to use at least a grade 3 or equivalent paper, maybe harder.

 

[Andrew O'Neill]

Developing for 3.5 minutes runs the risk of uneven development and or mottling.

When in doubt develop closer to normal. The latitude of the film should allow you to compensate while printing.

Many photographers use an exposure index of 250 instead of 400 in order to record sufficient shadow detail, so you are about a stop ad a half over exposed. This is just a suggestion, but I would use Rodinal at 1:50 and develop the film for 8 minutes at 68f based on the Massive Dev. chart. I think this will produce printable negatives. Good luck!

Thanks for all the advice. Im still learning photography and have a long way to go. Here is the results of my mistake. tmax 400 exposed at 100 rodinal 1+25 3.5 minutes 68 degrees 2 inversions every 30 seconds.

All the snow in the scene bailed you out on this one. You did, by accident, almost exactly what should be done with snow scenes. When you have that much white, it's a good idea to add a little extra light and pull back development a bit. The meter wants to see all that snow as medium gray, which it is not. If you go blindly by what the meter indicates, then the shadows become very thin, and will black out when you try to print the snow as white.

I agree with what Frank and Gary said. The general rule of thumb for snow is two stops overexposure, so you came up right. Tmax 400 has about as much exposure latitude as a B&W film can have. You probably could have metered this scene at asa 50 and still come up with a decent neg.

As Frank & Alex said you were lucky, but remember many of us here use Tmax 400 @ 200 EI anyway so to use you were only a stop out, not as much as you thought.

Tmax goes a little contrasty in Rodinal at 1+25 try 1+50 or 3+100 which gives better control.
