What you've missed is the lack of space behind the lens mount for placing your proposed diverging lens. Most SLRs need almost the entire registration distance to allow for the mirror to move up and down.

Why do light sources appear as stars sometimes? Taking a night shot with light sources involved, the sensor goes nearly always into saturation. This is because the dynamic range of the motif is much larger than the one of the camera. People are normally interested in the "illuminated darkness" rather than in the light sources. From the photographer's ...

I think the only possible answer to your question is "no such rule of thumb exists". The problem is just too complicated - as Matt indicates in a comment, how "distracting" the background is depends immensely on the content of the background, so you're first of all going to have to capture that. And if you can do that, you're pretty close to having reduced ...

I've never heard of the system that was described in the question but I can understand how it works. I can see no reason that it wouldn't work for fixed image photography as it would for cinematography. What concerns me is the quality. The large lens, ground glass (possibly milk glass), and the attachment to the camera lens would all have to be light tight. ...

The "telecompressor" you mentioned is a focal reducer, a device that concentrates the image in order to project it onto a smaller sensor. This approach reduces the backfocus distance (the distance from the back of the lens to the sensor). So it only works on mirrorless cameras using lenses designed for DSLRs (which have sufficient backfocus distance to make ...
