When I do people for photoshoots, one thing that helps with foundations is to go a bit darker than you normally would because people tend to get "whited out" from the lighting/flash, etc. If you do do bronzer, make sure and blend down the neck so it's all even and you don't have a dark face but a white neck. Moisturize because film picks up dry flakey skin easily. It depends what type of photo's they are too, wedding photos or magazine shoots, or portraits. The more professional the better, the less quality the more mistakes can be seen so make sure to blend like crazy. That's a common mistake, not enough blending, in shoots you can see the lines more than you might think. A general rule is to go a bit darker with eyes, lips, etc. too. I did a girl for a magazine shoot and in person you would've thought her eyes were soooo dark, but on film it was just perfect. Be careful with too much liner and mascara though because just like how film shows lines if you don't blend, it also shows clumps and smears. Be careful with alot of shimmer too, it can make you look too greasy because you might not see that it's glitter on film you just see a shiney face. It's alot of fun though, and I'm sure you'll do great! HTH!!
