I was thinking of taking a picture or scanning a demolens into a jpg, bmp etc file, and then modify it with photoshop for example. What is needed is to transform this picture into a OMA. like the one is obtained from Innovations when a shape is exported.
It would convert a camera or scanner into a tracer.
Does that software exist?
National Optronics has a tracing program that does that amoung other things. I'm sure other packages exist as well.Quote:

Is this still true? I've never heard of it and I attend all your conferences! :)
Will this work for all demo's? Some, I have noticed, fit tight and flatten after removal. Grooved and sun lenses should be OK because they tend to be thicker than demos.
It's still true. I know we have a small number of customer who use it extensively.
Mind you, it was (and is) intended to provide a reasonably accurate shape for surfacing calculations. As far as edging goes, I'd only expect it to work for a subset of rimless mountings - and you'd have to draw carefully.
Cool.
But It is more fast draw the pattern on the lens and go to hand edge the lens.

I actually have a video tutorial on how to do this but it is in German.
Alternatively, the Briot Alta Evolution Tracer / Blocker does exactly what you describe, including robust shape modification directly on the unit.
Please can you share your tutorial video. Thanks!
