This character wears a Corinthian helmet, not a galea. If it's missing the distinctive features of a galea—hinged cheekplates, a band around the forehead, neck guard—it probably shouldn't be tagged as a galea. Though in the case of d3rlord3, it's just straight up a completely different kind of helmet.
Isn't there a name for horizontal lens flare like this? Something about it being specific to movie cameras (and via association, creating a cinematic atmosphere)?
