So we all know starting a kit can be very expensive but with enough knowledge of products it can be very easy. There are a lot of sites to get you started. Camera Ready Cosmetics for one and another one is Alcone Company. Both of these sites offer many makeup palettes and other kinds of products to get your kit going. Camera Ready carries brands such as Yaby, RCMA, Obsessive Compulsive Cosmetics, and Cinema Secrets just to name a few. Alcone carries Ben Nye, 3 Custom Color, Kryolan Cosmetics, etc. I find buying palettes is easier than having to buy a bunch of little products, but for certain things it's okay. It's a lot easier to carry and organize a kit with palettes also. Most of the brands I use are Yaby, MUFE, and OCC. A lot of the theatrical makeup is very inexpensive and just as good if not better than some of those expensive brands. It's also pointless to start a kit at Sephora or any expensive makeup store that is going to cost you an arm and a leg. Makeup that photographs good is the kind you want to use.
