Hi!
- I re-worked the armchair's texture (bump/spec/colour)
- I made the shoes "thicker" (indeed they were really thin!!!)
- I re-modelled a brand new carpet and added bumps to it ("modelled" bumps - so it's not flat)
I also decided to make it brighter so I could get more contrast, as Sportler said.
I also thought about what t_3 said in order to give a more "dramatic" feel to it.
-> I lessended the DoF + added a second lightsource (outside the camera field)
-> The shadows that the light generates add more depth to the picture, and it makes the textures look better in my opinion.
Below are 2 tests with different Film/ISO/Gamma settings...
The 3rd picture is a heavily-post-produced version of the 2nd image.
I think it's better, what do tou think?
Many thanks again for your advice !
