This diagram shows a television studio.
00:04
We have a camera at a and a camera at b.
00:07
And the camera at a is an 80 -degree angle.
00:12
It shows an 80 -degree arc of here.
00:15
At the camera b, we wanted to show this same arc, because that's where the two anchor people are in this television news show, i'm guessing it would be.
00:27
So since this a is a central angle, that's equal to this arc.
00:31
And this angle b is the arc, the far arc, 80 minus the 30 degree arc.
00:39
That would be 80 minus 30 is 50, half of that's 25, that's where that comes from.
00:45
Now if i would like this angle to be 30 degrees, would i need to move b further away or closer to the stage in order to make that happen...
