Advanced Keying Breakdown: DESPILL 2.2 – Despill Techniques
Heres a tutorial about how to despill in ways to customize the color of the despill. We move away from gray despills towards more useful colors, such as the BG or the subject. Here I go over keylight, huecorrect, talk about keeping luminance values and using the BG’s Luminance to affect the despill color. I then talk about combining despills just like combing keys, and show a little trick with the alpha’s gamma prior to merging over. More to come!
