Re: Slide holding for Scanning - Ohnar and Other Options

The rig so far. To the right is the BPM bellows, 80mm enlarger lens and the DSLR. The aluminium construction on the left is my extension to the bellows rails to hold the Ohnar frame at the right distance and height.

My first attempt was off centre. Initially I thought I'd done something wrong when making the extension but then I noticed that the two M2 screw holes in the bottom of the Ohnar frame were slightly offset with respect to the centre line... hence the afterthought of two short brass arms which allow me to shift the frame to the side a little.

At the moment I'm using an old slide projector as the light source. Large amounts of cardboard are used to keep out stray light because I have no bellows between the lens and slide.

I still like the idea of the ChromaPro frame. Assuming one does not magically appear for sale any time soon then I will be making something similar. That will take a little longer.
