Been toying around with Daz for a while - never produced anything i was happy with so wanted to share something. Just applied some lighting principles i used to use when i had a small photo studio
Model is CJ Sirpa, with a main, fill and rim light and a small emmissive upwards "reflector" back into the face.
I think that the illumination on the front is a bit too much.
Generally speaking, you want 20% highlight, 20% shadows 60% mid tones on the skin.
Now, if the background is black...you have "Low Key" photography, and you usually want a bit more towards 50% shadows, and 50% light, with few mid tones.
For "High Key", you instead use a bright/white background, 50% highlights, 50% midtones, with almost no shadows.
LOWKEY Example:
HIGHKEY Example:
Also, I recommend this playlist [not just to you, but to anyone interested in lighting, really] for both character and environments:
