Inside the booth
Use depth carefully in a booth portrait
Change position without sacrificing a readable face.
A little forward and backward movement can vary a strip when the framing permits it.
Test the usable range
Make sample frames from comfortable positions and check headroom and focus. Do not lean into equipment or move so close that part of the face disappears. For two people, check both faces in the same frame instead of assuming the camera keeps every distance equally sharp.
Keep the sequence deliberate
Use small position changes and compare the full strip. If a frame becomes soft, return to the reliable position rather than trying to fix every capture afterward. The useful movement range belongs to your actual camera setup, not to a universal booth pose rule.
