setting up

a bit of a complex set-up for this weeks talk by Colin Metherell on 'stereoscopic' photography. 
It requires taking two photos with a double lens camera or two strapped together and projecting both then viewing through 'polarising' glasses. A bit like going to a 3d film. Interesting but I don't think it will be something I'll be trying out. Much too much trouble setting up to view them I reckon.
