Maintaining broadcast-safe luminance levels

Maintaining broadcast-safe luminance levels

- Another area of broadcast concern you'll hear raised is luminance. It's possible that the pictures can get too bright. Now, this is much less of problem when working with a all-digital workflow, but if you have analog components or things like traditional broadcast, you might have to introduce a clamp or make a small adjustment to your white and black points. Let's start here by opening up these three files. First, we have a raw file, and you'll see that this has a lot of data in it but there's a large spike here at the end of the histogram. As I start to recover the exposure in the file, you see that that data moves back down and areas that were just pure white suddenly have subtleties revealed, like shadows and texture. Now, instead of just doing this with one slider, if you have a raw file, you can make adjustments to the individual sliders for the different areas, for example, the black point, the shadows, the overall midtones, the highlights, and the white point.
