Heres latest interior work done for the client by me and Johny. Actually this setup kinda came along with the exterior experiments we did and played around in HDR rendering and tonemapping with Reinhard...
C&C welcome, though this is already finished work...
very nice. they are the same quality as johny's renders. sharp and clean and bright. are you using sky portal? those small spaces and corners are very dark when I do renders. I'm not getting good results with arealights in window opening plus photonmapping yet. can you share your floor setting?
