Digital booths
Use a colour target to profile a booth camera carefully
A target can characterise a camera under one light and setting, not every scene.
If skin and clothing colours repeatedly shift under a fixed booth light, a camera profile may help. Profiling must use a target captured under the actual illumination and should not be treated as universal.
Capture the target in the real setup
Place a recognised colour target at the subject plane and photograph it with the camera, light, exposure and processing workflow used for the booth. Avoid glare and check that no patches are clipped.

Build a profile for that condition
A camera profile characterises how a device records colour under specific conditions. If the booth light or camera changes, the profile may no longer describe the setup. Keep target measurements, software and profile version with the reference capture.

Validate portraits as well as patches
After profiling, capture people and clothing not used to build the profile. Check skin, neutrals and saturated colours in the final strip and print. A target test can improve consistency, but it cannot eliminate metamerism or make every printer reproduce every colour. Profile validation should include neutral tones and skin colours that were not used to construct the profile.
