Working on my project.
Understanding basic compositing nodes( Premult and Unpremult in NUKE.
Digital- Tutors/ how important for color correction workflow.
Alpha when red/ normally they are black and white/ depending on renders it may occur that alpha damped red channel.
ned to be aware of having a small mistake coming through to the final.
foreground and background when merged, need an alpha channel. total black equals 0 and white equal 1.
defining alpha by using shuffle copy, alpha=1, and 2 into RGB then locate where alpha is located among channel and tick the box accordingly.
shuffle done works just like a switchboard that changes color channel
Color grading can cause a break down if lack of understanding. so add unpremult before grade and premult after grade. this makes edeges looks fine and keeps the originality without darkening edges.
quick way to do, inside grade select un premult by rgb.alpha. do either one of thise. this option works with color correction > ranges> unpremult by rgb.alpha
clone done/
auto alpha to be put.
