see the new upload/folder

Subject distance 0.8 m

Depth of field
Near limit 0.79 m
Far limit 0.81 m
Total 0.02 m = 2cm

In front of subject 0.01 m (49%)
Behind subject 0.01 m (51%)

Hyperfocal distance 50.4 m
Circle of confusion 0.045 mm

So if I focus on peoples ears/eddge of head it should be fine?

Focusing should normally be on the people's eyes. Convergence and/or horizontal image translation should be determined by several factors, mostly subjective, but including the far point and the near point. When there are no serious window violations, this can often be behind the main subject. Numeric quantification can only apply to one specific image under one specific condition, never to all images or all conditions. In general, there is usually much more range available in front of the point of convergence or HIT than behind, and therefore more of the available volume may be utilized if this point is kept further back, such that more of the image is in the foreground. Also, there is more stereoscopic depth detail with closer objects.
