I think you mean 4 exposures of 1 sec..... of course, if the calculated 4 sec exposure did not need RF correction then 4 one second exposures should not need them either.Originally Posted by Kirk Gittings
The problem comes when you are in the 40 to 50 min exposures and you need to close the shutter. What do you do? In this case two 25 min exposures will work just as well as one 50 min exposure or better illustrated, five 10 min exposures will wok just as well as one 50 min exposure.
Of course, color film is much more demanding than B&W which is where I have most of my experience, but the theory should hold. And then, we have not discussed color crossover..but I guess that is a topic for another thread.
