6’ is pretty good for an AT screen.

On taking a picture …To be useful the picture would have to be at a known scale and have enough resolution.
A bit more work than just snapping a picture and may take more time then you want to spend or I can ask for.

But here’s what I think it would take …

.My screen size is a 150”. So you would have to zoom out the projector to get a 150” diagonal (131” width) .
Then take a picture with a ruler in it 17” wide (think that’s the width of the largest sheet of photo paper I have .. have to check when I get back home).

4K UHD is 3840 pixels in width. At 131” that 29.3 pixel/inch.
A 12 megapixel camera (4247x2826) would get you about 250 pix/inch at 17”
Which is about 8.5 pixels per projected pixel … hopefully enough to also resolve the weave.
so a 12 megapixel camera would probably be the minimum needed.

I can then print it out to scale, tape it to the wall, and get an idea of what it would look like.
