then one the correct exposure according to the meter. This
exposure adjustment is tricky and remember to turn the exposure
adjustment setting back to 0 (zero) when needed for normal
metering. What you are doing is metering, but making the meter
think it is darker then it really is and giving the film more light
with the + and less light when you set it to a - number]
