Hi Carbon,
If you have your perfect match in Bare Minerals and you absolutely love it, then I would stick with that for your wedding day, unless you've seen yourself in pictures with a flash and your face looks pale in comparison to the rest of your body.
If you would still like my opinions as far as the best makeup for combo/dry skin here are my top three of the moment:
1) Cinema Secrets Foundations (
www.camerareadycosmetics.com) If you e-mail Mary, the owner of the store, your picture, she can recommend a palette that will match your skintone. Most of the professional makeup artists I know have a few of these palettes in thier kit.
2) Face Atelier Ultra Foundation (
www.faceatelier.com) You can order samples for $1.00 each. I have them all and they are so concentrated, you can test them and still have some for your wedding! They have silicone, so they look smooth and flawless and are great for normal to dry skin types.
3) Benefit Playsticks (
www.benefitcosmetics.com) These are foundations and concealers in one and go on very nicely. A plus is you can go to your local Benefit counter and try them before you buy.
All of these foundations have no sunscreen, so you won't get that "mask" look you might experience with foundations that have any type of SPF.
As far as the best lighting for pictures, natural sunlight is always the best, but if that isn't an option, just make sure you have tested your makeup with a normal digital camera. My theory is if it looks good on a digital camera, it will look even better with better professional photography equipment.
I hope this helps!!
