Re: Temperaprint

I have been following the Temperaprint discussion with great interest.I have described myself elsewhere as a disciple of Peter Fredrick, the inventor and developer of Temperaprint and am happy with that description. I am not an expert on Temperaprint but I am a practitioner. I have written an article on the process for the British Journal of Photography. The article is dated 19.06.2002 and entitled Prints Charming( the editor's title not mine). The website is www.bjphoto.co.uk but it doesn't seem possible to get back issues without being a subscriber, though I do have a copy of the article on file. The article is based on one woman's way of working with Temperaprint and it does work. As to substrata, I have printed on a piece of polished marble as well as Yupo. I would be interested in forming a group with other Temperaprint practitioners out there- object- an interesting relationship. Hellena

  Hello all,

     Amongst my vandyke, cyanotype and gum playing around (yeah, at this stage of practice, It feels more like playing around..lol) I've also been attempting the temperaprint. I have a serious problem with it that I haven't been able to figure out. After exposure, when I'm developing the picture, I keep rubbing off the emulsion. I usually just end up with a white box where my negative was. I've been rubbing very gently, to the point that I'm barely touching the paper. I've tried various brushes from course to super soft to no avail. Several times I've been able to get peices of my picture to stay and those parts looked great, so I'm pretty sure it's not exposure. I thought maybe there was a problem with the eggs I was using, but I've gone so far as to drive out to the "country" and buy freshly laid eggs and still have the same problem. I was originally using Pot. Dichromate but am now using amm. dich (as per the recipe given by Mr. Fredrick) and I still have the same problem. To top off everything I've tried, I first started using watercolor paper (very heavily sized first) but now I'm using the recommended Yupo. There must be something I'm doing wrong, but I can't figure out what. If this was just something I was doing for fun, I'd move on to something else. Problem is, I love the look of this process, even more than gum and figured I'd ask for some assistance before I continue any further.

  Two more questions about the process I'd like to ask, for when I get it to work. Is there a difference in using Amm or Pot. Dichromates other than printing speed or the like? I only ask as I can get the Pot. Dich. locally so that's simply for convenience. Also, how fast does the egg colloid go bad and lose effectiveness? I only ask as I print in the morning and evening (before and after work) and was wondering if say, 12 hours would be too long to keep it? I'd test this myself, but I've already got enough problems....lol

    Thank you!
