I would appreciate if any member of this forum could further expansiate on slide film exposure specifically Fuji velvia rated at ISO 40. The rule of thumb is that you meter for the important highlight. However,by how many stops do you vary the exposure factor ? +1 or half stops. To further illustrate, for instance lets say the important highlight is metered at F16 using reflected mode measurement. Do I open up by 1, 1/2, 1/3 or 2 full s tops to correctly place the important highlight. I know that the exposure latitu de for slide film is vey narrow. I have tried to read a lot of books but ended up getting the whole thing confuse d. Informative explanation would be most welcome. From a newbie. Thank you.
