Hey guys.

I'm after something to put over my laptop screen to preserve dark adaptation out in the field.

I've seen red plastic velcro'd onto the screen and i've seen a sort of red film that can be cut to size as well.

What do you use, and where can I get it from (locally), and what's the cost?

I've heard that some art supply stores might have red plastic? Or maybe I should go to a plastic/glass factory and get an offcut?

Ideally the deeper/darker red teh better, and also has to be easy to see through..

Thanks
