I would think it is possible to dupe some negatives directly onto a new roll of film by contact printing. Does this render a reversed image? Has anyone done this? How much light does it take and how intense does it need to be? Thanks

Hi,
You will get a positive image with normal processing. You can also reversal process to get a negative. As far as light required, surprisingly little. If you wish to do this, I would suggest a low wattage incandescent bulb with a dimmer and a timer for repeatability. You can vary the distance if necessary to get a reasonable time.
Out of curiosity; what are you going to use dupes for?

Regards

I was thinking purely out of theory.

Do a search for ELDIA on the web....what a handy gizmo for doing just that! Negs to slides, contacts on paper strips, etc.....all for usually less than $10!

You can also use a slide duplicator for this purpose.

The film to use with the ELDIA, 'Fine Grain Release Positive', is available from:
