iso and ev adjustment. 7100
could someone please educate me on what ev and iso adjustments actually do, i know how they effect my pictures,
but with the tremendous iso improvement in my 7100 compared to d50. im finding that im using it more.. in low light to keep the shutter speed reasonable, when not using flash,or the subject is not near enough.
but ive never really played with the ev except to darken an image where i have blown highlights, but in most cases i would be increase the shutter or appetature instead..
