When a photog tells you "very little" makeup does he mean wear foundation plus little eye makeup or no foundation? I've got a shoot Saturday and I don't want to look silly!

If it's very little it won't take you long so just take your makeup with you and have him clarify when you get there.

Well it really depends, are you having a make-up artist "make you up" ? becase as a make-up artist if a modle shows up with make-up on it makes my job a little more difficult becasue now i have to remove your make-up , cleanse and tone your skin and moisturize it too. So you have just added steps to my job. But if your not having a make-up artist , he probably wants you to have a concealer and foundation base on your face ready to "add" to it. I would bring your make-up unless other wise told (if you have a make-up artist leave your make-up at home)
I havent encountered too many photogs who require "some make-up" on the face but heck you never know what people want untill you ask them
