I like a really matte finish, and I live in a hot, humid climate. I use a very tiny amount of silica powder buffed in, topped with a "regular" powder.
For the silica powder, I have used and like: NYX Studio Finish HD powder, MUFE HD loose powder, and NARS Crystal setting powder. I sometimes even use the ELF Studio HD powder. Honestly they're all the exact same thing, just finely milled silica. I use a tiny amount, and buff it in very well with a brush. I never have any issues in photos, and it helps to set my makeup and keep me matte better than just a "regular" setting powder.
On top of that I typically use either Rimmel Stay Matte (this keeps me matte better than anything I've found), MAC Mineralize Skinfinish Natural, or sometimes a random other powder like L'Oreal Translucide (which is a lighter weight powder) or Coty Airspun.
