Problem
The camera is mounted slightly off the intended eye line, making autofocus favor the nearest eyebrow or eyelashes rather than maintaining both eyes acceptably sharp.
Solution
Root Cause / Diagnostic:
Mounting the camera off-axis at an aggressive diagonal or high angle places one eye significantly closer to the sensor than the other. When shooting at shallow depths of field, the camera's Eye-AF locks onto the closest physical landmark (such as the outer eyebrow or front eyelash tips), leaving the far eye and iris visibly soft. This asymmetry creates an unsettling, optically ungrounded portrait.
Actionable Step-by-Step Fix:
1. Align Camera Height to Direct Eye Level: Mount the camera on a heavy-duty tripod so the optical lens center aligns horizontally and vertically with the presenter's resting eye line.
2. Switch Eye Selection to Near-Eye Lock: In the camera's autofocus settings, select "Right Eye / Left Eye Priority" or manually lock to the eye nearest the camera axis.
3. Stop Down by One Full Stop: Step down the lens aperture by one full f-stop (e.g., from f/2.0 to f/2.8) to extend depth-of-field coverage across both orbital sockets.
Pro Creator Tip:
Level your camera lens directly to the talent's eye height; keeping facial planes parallel to the sensor plane ensures both eyes share equal optical sharpness.
