Default global illumination

i test global illumination just for fun and i have some problems that you surely know how to resolve.(i have only one light in my scene)
-i want the back wall to be illuminated but when i increase photon intensity or decrease exponent,we are able to see the back wall but it makes the light that hit the sphere brighter.

-also we can see these little circle all around the scene(photon).i tried to increase global illum photons but they become smaller and we still see them.how can it be clean.maybe its not clear lol.

hope someone can help me.

The photons are not gonan make any difference. What you are looking for is to make an ambient light. It's that simple lol

photons will make a difference.
leave your exponent value to the default, 2
increase the light bounce in the gi settings. and also in your shaders MR settings.
start with a small amount of photon, then increase gradually.
use a low intensity FG setting to clean up final image and get rid of artifacts
