You can use both of them for pics, no problem with flashes.
LOW COST OPTIONS:
I love using Revlon ColorStay Foundation.It's an oil-free product that will give your skin a fresh look. I use SAND BEIGE shade. It is a MAC NW/NC 20/25 dupe because its undertone is neutral. You could choose between two shades that are paler than mine. The IVORY shade is the palest one.
Low Cost: Revlon ColorStay + Catrice Prime and Translucent Loose Powder
High Quality: MAC Matchmaster + NARS Loose Powder
Or you can buy a white foundation (Illamasqua Skin Base Foundation in 1) and use it as a modulator with your current one. NARS Loose Powder or Too Faced Prime&Poreless are expensive, but very good investment, in my opinion.
