As the title says, something related to visual images and sight.
Standing distance[]
Here I have drawn an image of comparison of different persons at IDENTICAL height of 1.7 m looks like when standing at different ranges.
The following formulae have been applied:
- Distance from point of view to object = object size * panel height in pixels/[object height in pixels*2*tan(70deg/2)]
- Object size = 2*tan(70deg/2) * distance from point of view to object * object height in pixels / panel height in pixels
(Human height is always 1.7 m and pixel height is meant to be 1000 px
I did make the panel 1250 px to illustrate the effect of the (2nd from left) character standing at higher pixel height than the panel height
The character standing at 1000 m away should appear as a dot at the horizon and therefore is meant not to be seen clearly.)
Tally - Standing distance[]
| Distance of character from camera (m) | Height of character in panel (px) |
|---|---|
| 1.213925806 | 1000 |
| 1 | 1213.925806 |
| 2 | 606.9629029 |
| 5 | 242.7851611 |
| 10 | 121.3925806 |
| 50 | 24.27851611 |
| 100 | 12.13925806 |
| 500 | 2.427851611 |
| 1000 | 1.213925806 |

So this should give a good estimate at how character standing distances should actually be portrayed.
For your reference, the farthest distance a human eye can detect a candle flame is 2.76 kilometers.
