I find using magnifying lenses a bit to confusing when painting.
When I first started painting, I figured using a light with a magnifying glass in it was the best way to go for detail work etc, but I found that, when I tried painting under the lens, it screwed up my depth perception and the model was either farther away than what I thought when trying to use the brush, or, when I tried to compensate, found that actually applying the paint I was making large strokes for something that was extremely small. I gave up on it altogether.
Now I onlly use the glass for exaaming parts of a minni, but all my painting is done away from the lens.
With experimentation Im sure I could get the hang of it but.. why?
My suggestion would be just to go to the stamp collecting corner of your hobby store and buy a cheap hand held lens for examining and not to paint with it.
