If this is covered elsewhere please point me in the right direction. My question is rather simple, do most people shoot real LUM, or do they use the RGB subs to create a Synthetic LUM? Is there a best practice or is it different for different objects?
Until about a year ago I always captured lum. Then I started creating a synthetic lum from all the RGB subs combined or even with some real LUM added in. I found that I liked that practice. Just curious what the gurus here think!
