i shot this with 2 strobes on softboxes
The trick for me is really in fill cards.
Metals reflect their surroundings, so probably need to fill the ugly reflections with white card and control the distance..
I also used a hoya cheap polarizer. But i guess it didnt do much to the face glass as it was an straight on angle ...
and
you guessed is, photoshop!!!
these watches if u just use your eyes to see it, its perfect, but under the macro lens, every blemish gets amplified! so gotta clean the subject well, and clone away those imperfections during posts.
