I make several channels where the logos have pure blacks and whites in them. As I understand it, the colors must be between 16 and 235.
1. Is this true for HD and SD?
2. Does anyone have instructions for converting graphics to this color space automatically in Photoshop? I'm working with the latest CS6. I tried assigning the color profile NTSC SDTV which I believe is the same thing, but it does not convert the pure blacks and whites.
Thanks
