Show some respect and make your point, then shut it. If that point is that we SHOULDNT be switching from 70 fov to 30 fov because 60 fov is realistic, then PROVE IT or accept that I will REJECT IT.

who is being rude??

I think, when it come to making a judging on another, what you are really doing is just looking at yourself in a mirror and making the judgement based on who you see there ... "jerk"? ineed

Name calling just suggests you have no firm basis for argument

and if you had of read an earlier post, it was suggested that normal FoV combined with zoom, would be far more effective (when scanning) than switching to a smaller FoV, or... a larger one. Why? for the very same reasons you, yourself, have pointed out.

yet you say 39 degrees is normal and to use zoom... this is just another can't spot the dot whinge thread - pure and simple

The human eye can see up to approx 180 degrees, side to side, without moving the eyes or head - total vision
Vision in each eye is less than this and approx 90 degrees off the side with about 60 to the inside (bridge of the nose gets in the way) inverse for the other eye. up and down varies and is slightly less again. Most have the higher angle though is comprised or the peripheral vision.

put a book in front and you'll be able to read it... put it off to the side, and with holding the eyes straight ahead, you may see the book but you won't be able to read it. The range at which the book will be able to be read consists of an angle of about 60 degrees.

The other bit which needs to be taken into account, is the screen is not photography... it is projection.

If you move closer to your screen... it gets closer, that's all that happens
