Step 2/7Natural light, in order
Same window, opposite instinct: put black where the board was. Daylight has no dimmer, so subtraction is your only ratio control — and it is worth nearly three stops in the shadows here.

Step 3/6Subtractive lighting: flags, cards and V-flats
Daylight has no dimmer, so black is the only ratio control left — remove it and the shadows open by nearly three stops with the window completely untouched.

Mood variations

Portrait subject — Closer Flag variation of Window Black Negative Fill Portrait. — Closer Flag
Move the black fill closer so the far side of the profile crushes darker and the lit ridge reads sharper.

Portrait subject — No Negative Fill variation of Window Black Negative Fill Portrait. — No Negative Fill
Remove the black board — room bounce lifts the shadow side of the profile and shows what the fill was doing.

Portrait subject — Bare Glass Punch variation of Window Black Negative Fill Portrait. — Bare Glass Punch
Lose the sheer so the window goes harder on the lit profile ridge while the black fill still holds the far side deep.

Final look

Base setup

Rooms bounce light everywhere, which flattens window portraits. Black negative fill absorbs spill on the shadow side so cheekbone and jaw shape return — the window is still the only source, but the contrast becomes intentional.

Key notes

1Put the black fill close — distance kills negative fill faster than with a reflector.
2Turn the face slightly toward the window so the shadow side falls where the V-flat can eat spill.
3Watch the shadow-side eye; negative fill should deepen, not erase, the catchlight.
4Compare with and without the black board in the same pose so the lesson reads instantly.
