Angsize question

[Wokistan]

By assuming a typical human field of view it allows one to estimate the size of an object if one knows the distance from the point of view or estimate the distance to the point of view if one knows the size of the object.
	~ Angular Size​

My question is, why are we saying a typical human field of view is down at 70 degrees? There seem to be two issues with this. Firstly. Wikipedia has actual sources for their stuff and they put it at 210 horizontal and 150 vertical. Secondly, this doesn't seem to take into account that vertical fov isn't going to be as high as horizontal.

Calc group plz

I believe the 70 degrees assumption comes from Minecraft.

The human eye works in very strange ways. Despite the eyes technically having such a large FoV if one used a camera with such a large FoV to make pictures the pictures would look unnatural for us. (See Fisheye Lens)

For a long time there was a rule of thumb amongst photographers that a lens that produces a picture that looks "natural" to us has a FoV of around 40┬░. In recent trends that may change, though. For example the iPhone X uses a camera with a 65┬░ horizontal FoV and still looks natural.

Not sure where 70┬░ exactly came from. It's one of the OBD artifacts in our calcs. It doesn't seem too wrong, though, given the above.

Who plays Minecraft at such a low FOV

Even if this is how it is for photographs I don't think we should have that take precedence over how the eye actually works though. What feels natural will vary from person to person anyways. I'm fine playing FPSes at 140 FOV, for example, but my brother thinks it looks too weird at that. Using something that can skew so much off of other variables as opposed to a thing that can be measured seems bad.

The thing is, things will be drawn or recorded in the way a camera perceives it, as the result is supposed to be a good looking picture. The result is not a visual stimuli send directly into our brain, where a FoV matching our eyes would look better.

For instance, our eyes also perceive things in a very different way regarding resolution:


However, nobody would draw a picture in the way our eyes actually see it. Everybody would draw it like a camera does.
