For studio-photography makeup or any sort of makeup that includes flash photography (editorial / event / bridal) there are certain makeup products that can turn your work into an epic-fail episode. Foundations with high SPF, certain mineral powders, concealers & foundations that have light-reflective ingredients, overapplied shimmer bronzers and glitter powders, all that can make the skin appear ashy, masky white or -in the case of shimmer/glitter products- exaggerate fine lines and pores or produce a "sweaty" look.
But the trickiest products i have ever come across are the silica loose powders like the Make Up For Ever "HD" powder. Transluscent-invisible, colorless, talc free (100% silica), when this powder hit the market some years ago it revolutionized the no-powder "natural" makeup look.
And it's absolutely true. For daytime or for tv camera work it does wonders (especially with the demanding HD equipment and formats where the makeup needs to be "almost not there")
BUT !!!! for flash photography it can be disastreous! Invisible as it is, it's very easily overapplied...and then disaster hits!
Here's me without flash
and with flash
When i first bought the MUFE "HD" powder ,back in 2008, and took my test pictures i was horrified by the outcome!!! Mostly because noone had told me "becareful with flash photography"!!! I only use these type of powders on day-makeup or makeup for tv / film.
