Hi Neebelung!
They are partially right...partially. When you are in a situation such as a photography studio, it's important to know what type of lighting the photographer will use as that will dictate what will not read well in the pictures. If the photographer is using "ring lights" or something similar, anything shimmery or light reflective will create a "hot spot" (a while glare) on that part of the skin.
Now for bridal purposes, unless those are the conditions under which you are taking your pictures, anything with a slight (slight!) reflective nature will be ok. Some translucent powders have light reflecting qualities, but if you use, say rice powder or cornstarch powder, you are fine. Those are matte, sheer setting powders that will work fine.
What makes your face pale and your body appear to be a darker color is SPF in your foundation. SPF is found in mineral foundation and any foundation that says it contains SPF. The reason is because SPF is meant to reflect any light, even those produced by a camera, so it will reflect the light, giving the illusion that you are wearing a foundation that is WAY to light. Be careful, as many tinted moisturizers also contain SPF.
So for professional makeup application, artists will use "pro" products (the stuff that we use for TV, film, runway, photoshoots, etc.) that we know read well on film. Some brands that make great products are:
1) Nixie Cosmetics (
www.nixiecosmetics.com)
2) Smashbox Cosmetics (
www.smashbox.com)
3) Face Atelier (
www.faceatelier.com ) Bonus: They will send samples of virtually anything for $1.00! Try thier foundations and lip glosses...they are to die for!
As for bronzing powder, there are matte bronzers out there (not as easily found as the shimmery ones, but they are there) so that would be perfectly acceptable...if you need a bronzer. Bronzer is generally used to give you a sun-kissed glow, but if you are super pale, or your foundation is matched perfectly to your skin, you should only use bronzer in lieu of contouring or as blush. N.Y.C cosmetics has one for $2.99 that you can find at Target, CVS, Walgreens, etc. and it is just great! So many makeup artists have begun using it because it looks so natural and is easy to blend.
I hope I have helped to clear up a few of your questions!
