I need some tips on getting the best skintones. I may be shooting in a studio type setting (not an actual studio). I am using a Sony 717 that tends to give somewhat cool pictures. I have a warming filter that's coral colored and Moose's warm circular polarizer. Any suggstions on inexpensive or homemade lighting, reflectors etc.? Exposures, ISO, aperture (I only have 2.0-8.0), flash, distances, anything? Are there different lighting techniques if some of the pictures will be converted to B&W?
