Advice needed w/ old school equipment.

I've got a bunch of old lenses and RF lenes over the past year along w/ an old Gossen meter. My question is how to compesate for colored filters w/ that set up?

Thanks,
BIll

The exposure factor should be written somewhere on the filter box. Usually they are 2x (one stop) but not always.

If you don't have this info, put it on a metered SLR and check exposure with and without filter. That will tell you how much you need to compensate on you external meter (ie set 200asa instead for 400 if it is a 2x filter, etc...)

I generally add a stop of speed for yellow, two for orange and four for red. I figure there's so much variation in using a mechanical shutter and Sunny 16/hand held meter, the if I'm off a little on my colored filters, it'll be the least of my worries. Ha, ha, just remember to take the filter off when shooting colored film. We've all done that!

Rule of thumb: Yellow (Y2, Y48) 1-Stop; Orange (o56) 2-Stops; Red (R25, R60) 3-Stops.

Brian:
So you mean the full stops? Like from 2, 5.6, 8, 11, 16, 22?
Thanks,
