pausing from drawing to do a tiny lighting demonstration for the anon.
i’ve marked the major light sources. YELLOW is the strongest. PINK is the same as yellow (the sky, basically), but it’s coming in at a steeper angle, so it’s not as strong. the place where pink and yellow meet is where you’re most likely to find the “natural” color of the person you’re painting. forehead, collarbone, on either side of the bridge of the nose, etc.
the BLUE is the reflective lighting.
in this case, it’s false hollywood lighting. if you look in misha’s eyes, you’ll see white reflective dots. those dots are actually the reflection of one of those big white cards you sometimes see on film sets (i have no idea what the official term for them is). film crews use them to reflect light up into actors’ faces so you can see them better.
if i were using a difference source photo, the BLUE might come from water, a bright sandy beach, or even the shirt the person is wearing. it’s secondary light reflecting onto a person’s face from something else that’s being illuminated by the primary light.
i hope that helps? any place the light isn’t touching is the elephant graveyard where the hyenas live. so don’t go there.
those are just the darkest places. under his hair, inside the hollows of his eyes, under parts of his chin. the hollywood lighting card thingys are meant to get rid of those shadows, so misha is actually really well lit in this shot. :)
