Most definitley one of the masters of Cinema 4D - 'pupi' has done some extraordinary works, including some as tester for new versions of the program. As with all the 'Masters' - there is not enough space to do them justice. You will have to 'Google' them all.
Russ is a long time on the scene - a former GUI skinner if I'm not mistaken. This is a classic example of all the relevant techniques: modelling, texturing, lighting, rendering and presentation. Not sure of the software used, but who cares...
I don't know much about the artist, but he can certainly produce a stunning product shot! Apparently he had access to original graphics frm the manufacturer for this, hence the stunning graphic work.
Rochr, always an inspiration. Used to use Bryce before Cinema 4D - and surpassed my wildest dreams in both programs. Check out his other works out to be truly amazed...
