Exposure question

If I accidently overexposed a roll of film by one stop (ev +1/2

instead of ev -1/2) is there any way that this roll can be salvaged

in the processing or will I just have to live with my mistake. The

film was Sensia 100.

 

Thanks in advance for any answers.

Find a lab that will do push/pull E6 processing and have them "pull" it 1/2 a stop.

Sorry I misread your question. You should have them pull it one stop, as if you exposed it at EI 50.

Was it a one stop or half stop overexposure? EV +1/2 is half a stop. If that's all, I wouldn't worry about it. A 1/2 stop overexposure isn't much for Sensia 100, a pretty forgiving film as slide film goes. If anything the slight overexposure could help some of your photos.

 

Keep in mind that a lot of photographers prefer to rate Velvia at 40 rather than 50, a slight "overexposure" that those Velvia shooters say is not an overexposure at all but an improvement.

Lex, he meant to underexpose by half a stop, but instead he overexposed by half a stop. This means that he exposed by a stop more than he intended. An entire stop is just too much for sensia's latitute; I would get it pull processed one stop to get back the exposure that you intended. By prepared though, pulling will likely decrease contrast and saturation slightly, though with only one stop the effect may not be drastic.

If its regular stuff get a half stop pull to restore the film to its

specified rating. If it's special and highly exposure critical get a

clip test from a pro lab. run at a one stop pull. If you like the

result have the rest of the roll processed the same. If the

combined effect on exposure and contrast is a bit out, settle for a

half stop pull or even none. The lab, if it's good, should be able

to tell you how far the exposure is away from normal down to a

half stop.

 

I really wouldn't worry about this- it happens a lot and indeed I

suspect that a large proportion of slide film is exposed at least a

half stop away from the ideal in any case.
