How to have flawless foundation in photos?

Oh, you're right! Flash is our worst enemy, and that's why I hate to take picture using flash. The reason why our face looks whither is because the flash is too close to our face, if the picture is taken from afar, it won't be that bad actually. I am pretty sure you're trying to take close up picture using your camera phone, making your face whither, and sometimes even make the color of your face somewhat different with your neck and other body parts. To make the result of the photo not too bright, I usually try to use better and warmer lighting to help reduce the flash light. The oily condition should be able to be covered with some powder, but that could be difficult if you're not prepared. I usually have a facial bloating paper just in case. I hope it helps. Good luck with your picture

I agree with Weirdology. Try to avoid using foundation that has a lot of SPF in it. SPF tends to reflect light so during flashed photography your face would look shiny if you're using foundation with a lot of SPF. If you can find one that doesn't have SPF, the better. But if not, you can use one that has lower SPF. On my wedding day I used Revlon's Color Stay Mineral Foundation in SPF 10 and it worked so well with the flashed photography. I didn't look pale/ghastly white on my wedding photos at all. Even the unedited ones. There are also foundations out there that are meant for photography and those are called Photo Finish Foundation. I haven't tried out those yet because most of it are really expensive but I heard that they're the best foundation to use for photography. You might also wanna stay away from foundations with shimmer on it. Just use the ones that has a matte finish and again, lesser SPF. Hopes that helps :)

you should set up your face first. Before you put on a primer wash your face with cold water or even better rub your face with ice. This will close your pores reducing oil on your skin. I learned that from my make up artists during beauty pageants and my wedding. The pictures looks awesome.
