I've not shot chrome film since I started putting my cameras on manual. Normally, when I expose for my subject (generally the face), I open up a couple of stops over the meter reading, or more precisely if I'm using my gray card. With positive film, since everything is backwards, given the same situation, do I open up 2 stops, or close down 2 stops, from what the meter says? This is a pathetically beginner question, I know...ps I'm using a spot meter now...yippie.(posted 8827 days ago)...And any tips of RDPIII, which is what I'll be using, probably half-to-two-third length blown-out white backdrops with colourful clothing and an Asian model...with really colourful, wild make-up.
