Slide holding for Scanning - Ohnar and Other Options

Thanks again for all of the input. I've now made a slide holder along the same lines and find it much easier to use than either the Ohnar or BPM slide holder. Mine is narrower so that it can drop into slots in the brackets on the bellows extension. I suspect the jaws are also thinner because 1/8 inch brass was what I had so 1/8 inch brass was what I used - it is only just thick enough to make pockets for the springs but I managed to make the holes without breaking through.

I added a little knob to help with opening the jaws without getting my fingers near to the slide. The sideways stop is drilled off centre to allow 1mm of sideways adjustment to find the best position.

I've bought a bigger opal panel but at the moment I'm still using the opal screen from the Ohnar copier behind the slide. Making some less 'bodged' arrangements (than chopped up cerial boxes) to block stray light is still on the 'to do' list.

Nice, a more classical approach with the brass.

Finished my new slide holder a week ago, used 5mm sheets of grey PVC and some magnets for the clamping force. With the turned enlarger head system I could not go for a single slide insert system but used a narrow slit approach where I shift the slide in the center with one copied already and the one third in line. Sigma macro lens + camera in AF wide field mode.

Met vriendelijke groet, Ernst
