This is render I did for an integration. A lot of the time, there needs to be new products rendered into an existing photo for e-commerce. I try to recreate the scene as accurate as time allows so reflections won't need lot of retouching. . I've built a pretty massive library of procedural materials and tiles that really speeds up the workflow. The retouchers at Kohler have been pretty happy with my outputs so far!
You learn a lot about studio lighting and camera set-up when you are trying to replicate what the photographers did on set. Some times camera matching can be the hardest thing. Especially with shots like these!
