Extremely dubious subject. I utilize 3dsmax 2014 and it has a gamme estimator implicit while stacking bitmaps.
Since a couple of months I use Gamma 2.2 in Tonemapper and set camera to direct. I change with ISO, etc to simply make it look great. This gives me better crude rendered pictures with less immersed hotspots.
In Photoshop I apply the look I need. Don't have the foggiest idea whether its the best approach to work however for me the pictures look progressively normal.
I think in 3dsmax itself I likewise set the gamma to 2.2 on the off chance that I recollect right.
