Quote - A question:  I have rendered using your Environment Sphere Dome, and I think what you did was excellent.  How is that when I render I get fuzzy background?  Is it because of the low resolution image?  Should I move my camera or better yet, size the sphere down a bit?

Other than that, I like it?

One of the most curious things about the environment sphere is this: changing its size has little to no effect on how big looks, or on how fuzzy it looks.

The fuzziness is due to you looking at a tiny part of the photo. You need a really big photo to get away with looking at only a tiny part.

Everyone should experiment, please, and learn how things work. Change the sphere scale to 50% - render it? See no change. Try 10%. See no change. If you get small enough, though you'll start to see perspective distortion - i.e. where your camera is will change how it looks.

Try changing your camera focal length. Go smaller. Go bigger. Move the camera to bring your subject into view at different focal lengths. Observe the changes in the background.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
