Definitely depends on skin. I was in my dad's wedding this past weekend and I used different foundations on every person. For his wife, with her more aged skin, I used a really moisturizing liquid. For the younger girls with oily skin, I used Tarte's amazonian clay foundation (it rocks). However, that was a bit drying for my youngest sister so I mixed the foundation with moisturizer to make it more emollient. Definitely make sure everyone is moisturized! I found that liquid just photographs the best for me, and it's easiest to blend into a natural look.
