Dial stuck on 100.

[chris64]

Another question... my TLR film speed dial is stuck on 100ASA and I have lots of 50ASA film. If I photograph using the 50ASA with the dial set at 100ASA then what processing adjustments would I need to make when home developing?

What TLR does not allow manual adjustment of shutter and aperture so that you can compensate by adjusting one of them after the meter has given its advice?

Is there a light meter in the TLR?

If 'Yes' then use it and double the exposure it recommends.

If 'No' then the ISO setting has no effect at all and is just a reminder for you.

Either way processing is not affected.

If there is a fully automatic TLR then I would be surprised, however some models have built-in light-meters.

As we have not been told the specific camera, presumably the film-speed dial is either on an in-built meter, or on a film-speed reminder. In the latter case there is no problem of course. In case the meter-dial is stuck, just open the aperture one stop or go to the next slowest shutter-speed in order to double the amount of light in your exposure.

edit: Hahahah, looks like we are all suggesting the same . . .
