The Portrait Booth

The core recipe. Eight feet, f/10, a measured mark, and light people can glow in. Find the wall, then the mark. A ~6-minute recipe for Hosts.

Standards

Booth to backdrop

8 ft

Closer than that and white turns into a gradient.

Aperture

f/10

Flash

Full power at the proper angle

Even coverage across the whole backdrop, not a hot spot.

Zoom

The exact mm, every time

Zoom in slightly on white so the corners stay white.

Guest mark

The knot on the rope

Keep moving people back to where the light is best.

Clean floor

8 to 10 ft

Full-body portraits need it.

Find the wall, then the mark
Center the setup on the room. Lay the measuring rope from the backdrop and drop the booth at 8 ft. Even lines, no offset shooting.
Backdrop up, straight, zipped
Six panels wide. Zippers closed. Nothing sagging. Check it twice: right stand, right panels.
Light in, then measure it
Set the strobe at the proper angle for even coverage. Meter it. Under-exposed misses our look. Micro-adjust power for skin tone and how far people stand.
Camera: f/10, the mm, the headroom
Dial the zoom to the exact mm. Set headroom at the right height and clamp the left and right margins.
Printer on its own table
Never on the floor, never on the booth. A second table for drinks keeps the shot clean.
Tape everything
Every cable down. Nothing dangling. Hide what no one should see.
Test at real distance
Real backdrop, real mark, real photos. Then wipe the screens before doors open.
Photo and video of the finished setup
Required. Attach it to the event. Keep checking lighting and framing all night.
