Hey,
I would like to know, what modifier is good for background for those portraits face and shoulder or half body where it is round or oval lighting? how to place the light, from the top tilting down to the background or placing it down and tilting it up to the BG behind the subject?
Also, is it better to have the color needed by using a filter on the light or buy having some plain BG color [Such as gray/white/chromakey,...etc] and change it with PP?
If using a filter, how can use it if we use a modifier on the lighting itself?
