They do not reflect like bounce; they transmit and scatter. Effective sun size grows, shadow edge softens, contrast drops.
Modifiers
Scrims are diffusion frames — silk, 1/2 stop, 1/4 — placed between sun and subject to enlarge the source.

What it looks like

They do not reflect like bounce; they transmit and scatter. Effective sun size grows, shadow edge softens, contrast drops.
Midday portraits, outdoor fashion, handheld sun lessons, overhead daylight on sets.
Softer shadow under chin outdoors; lower contrast; scrim may be invisible if outside frame.
Keep scrim between sun and subject — if sun hits face directly, scrim is wrong place. Assistant holds scrim as close as comfort allows for max softness.
Closer scrim = softer; larger frame = more even coverage for full body. Wind = safety issue — sandbag stands.
Scrim off-axis so sun still strikes face edge. Fix: walk the sun line with string or shadow check on ground.
Open shade + reflector is the backup lesson when scrim unavailable — teach both same shoot.
