This was a self headshot lighting test before a recent session and I felt like I nailed the subtle squinch without going too Hollywood with it. Also was happy with the lighting balance using a quick and dirty 3 light LED setup (ring light for eye catchlight, fill light over subjects left shoulder for separation and colored light on white backdrop) since I usually use strobes for headshots.
