hanging over this setup:
a collage compiled in a hurry
In the 7th picture I have put two A4 page´s (taped to each other acting as a diffusor) on top of the setup. Not visible are the fluorescent lights but they are directly above the paper diffusor.
The difference between the 7th and 9th picture are the paper ´sides´ that I folded down to let more light ´hit´ the target.
I used the (empty) glasses to make sure no gaps appear between all the pieces of paper as these openings will reflect on the watch. If I find a shoe-box-lid sized A4 I will try that as a basis for the setup.
It is really easy; much easier as the pictures show.
