My attitude to the glow effects is that if it works why not do it?

There could be many reasons why the effect doesn't work on Vader so adding a few here and there where it adds something artistically to the non-masked characters makes sense to me.

There aren't that many shots where it would have added anything to ANH anyway (the Death Star corridor was too light and Luke on the Falcon and in Ben's hut weren't combat situations so nothing artistic would have been added to the scene by adding the glow, the only scene where it might have added something was in the Cantina scene) so not having it in ANH:R isn't really a problem for me.

The glow on Luke with Vader baring down on him adds to the sense of peril, so it does something artistically, a glare on Luke trying out his sabre for the first time doesn't really add much.

Though I appreciate it's more work and as always it's Ady's edit so the decisions are all his to make.
