use RAW. Better more exp - (make sure histogram toward the right side, make sure shadows have enough exp.to the point right edge is not over the wall. If dark part of pic not exp. enough, PS will produce lots of noise in those areas.) Low ISO if possible.
1. make sure enough exposure. 2. make sure in focus. 3.good contrast. not too gray and not too much contrast. 4. don't over use contrast and brilliance color
