Thanks for all the good info here! I just got a brand new a6500, and I film plays in small theaters in LA and there a lot of blue, violet, and red lights I am always dealing with. I tried profiles 6 and 4 and those settings seemed to flatten the colors (which could be good for post), but I am wondering, does anyone know the best picture profile settings to film live plays/concerts with changing colored lights that will be broadcast on HD tv's only and that need little adjustments in post are? Thanks

I think It's 7 coz it's the flattest. it also forces you to use a high iso but it shouldn't be a problem since you are shooting in theaters
