One eye in focus, was Depth of Field question

Steven Morton
 

I'm with Jen. Generally the eye closest to the camera is the one I think
should be in focus.
Or add a bit of swing and have them both in focus.

All the best

DoF is not equally split, there is more towards the back.
So if you focus on the rear, the closer one will exhibit greater softness than the one exhibited by rear if focus is set on the font.
In other words (and I know this is an overstatement) : you focus to the front and the second one is soft or you focus to the rear and the other one is blurred.

Composition also plays its role:
An eye on the center should be sharp
An eye on the golden section should be sharp.

That being said, I strongly believe that such a limited DoF is merely a cause for trouble; it offers nothing to the narration.

Although this is often true, it’s not true of the split across eyes in a close up. Let’s be more precise.

At higher magnifications and shallower stops depth of field is split 50/50 behind/in front of focus.

At lower magnifications and deeper stops depth of field becomes 100/0 behind/in front. Hyperfocal distance takes effect before you really see this though.
