Fuji FP 100C coming out underexposed?

Fuji FP 100C coming out overexposed?

I took some test shots today with some Fuji FP100c, They came out kind of overexposed. I metered them at ISO 100 (Reflective). They kind of looked to me about a stop or so light. Should I be metering it a little lower?

I didn't think that my bellows extension was extreme (maybe 12 ") but maybe that had something to do with it, I shot some film as well to compare, but won't have that developed for a few days....

Thanks in advance, ad

I've shot tons of FP-100c with manual cameras, either a Mamiya Universal or a view camera. I've always found exposing at ISO 100 has given me good exposures. You say that the images are "light" but are "underexposed", which is contradictory. If the images appear too light, they have been overexposed.

vndonovan, you are right, I edited the thread...

If you use exposure times of more than 1/4 sec the reciprocity failure of the fp100c has to be considered, otherwise you get underexposure.

In that case, double check your metering. I've mostly used incident metering with FP-100c, with good results. If you are using a reflective meter, don't meter the overall scene but use a gray card. Or meter your hand, but then remember to open up one stop if you have light-colored skin.
