He also explicitly asked for other suggestions pertaining to color accuracy, sharpness and lighting setups. You might want to consider reading the initial post again.
Some lighting problems can be corrected in post-processing rather easily. Some can be corrected only with great difficulty. And some can't be corrected. Rather than complicating the issue as you suggested is happening, the issue is being discussed comprehensively. That seems to be a good fit with the OP's first post, which (again) addresses lots of concerns.Lighting etc can all be corrected in PP. Why complicate the issue?
