Im an aspiring mattepainter and therefore big part of my self-educating is working with nuke, especially because of 3D projections. They are not a problem, however while I develop my showreel, I want to deliver best possible shots, which includes also some kind of finishing touches. Im not sure whether those are part of the compositors or mattepainters job, but I think understanding them might be an another step forward.
So, my question is what kind of finishing touches (i.e. grain, chromatic aberration, dof…) you guys use and when? All I know all of these support that natural feeling from the final shot, but often I fing myself struggling about using them correctly and in right amount to make it look just right. For example the grain. I use the grain node and it atomatically chooses some Kodak preset for me… how do I choose the right one? Also similar question on chromatic aberration - sure its easy to divide the shot to the separate channels via shuffle nodes, but how do I determine the correct color combination (I mean that outline that it creates - red/blue green/blue etc…)
So I would appreciate if anybody could share his knowledge and tips for this and finishing touches generally. I believe Im not gonna be only one who may find these informations useful.
Thanks in advance
