Hi all,

I posted this thread on APUG, but since I now hit on a very interesting document about Hippolyte Bayard's direct positive process, that I think you people here on Hybridphoto will love too, here is the link to the APUG post:

(there was a url link here which no longer exists)

I think some of you might like to have a go at it with this background info and instructions...

Show the "positive" results here if you get any! I would be very interested to see it.

Marco
