Thanks Carlos, I am sure you are correct...pan films
only.
I just saw your prior post. The shot you directed me
to...do you recall
the exposure compensation used? Was it about 3.5 stops?
Thanks,
Charlie
If there are two filter factors one is probably for
daylight and the other for tungsten.
Filter factors can be a bit misleading since the
transmission of a filter in its "pass-band" to use an
electronic term, is pretty high. If the factor is the
decrease in transmission of white light it can result in
overexposure of objects the same color as the filter. Some
experimentation is necessary to determine what factor, if
any, should be used. Too much exposure tends to wash out the
effect of the filter.
