Photographically speaking it's actually quite a complex topic, even on the ground: the way focus is affected by the curve of the lens used, in relation to the distance, perspective and/or curve of what is being photographed - there are even special lenses used to account for this affect (tilt-shift lenses), BUT, ironically, they are often used in photography and film to PRODUCE the effect where it doesn't appear - so it gets even more complicated:
The effect is often used to make large expansive scenes appear distorted and small, to make landscapes look like they are miniature models, or further away than they are.
