Cyanotypes from Ambrotypes…

Printed some quick cyanotypes from Richards plates.

Exposure times were around 13 minutes, just cant seem to get them down from that using the UV face tanning unit. These were on Fabriano Artistico paper.

From a whole plate ambrotype…

Second whole plate…

The first print toned in Liptons green tea with lemon…. less than an hour.

From one of the 12×15 inch ambrotypes…

Sorry for the iphone shots. These are all wet prints, I’m hoping they’ll darken a little when dry. It surprised me that the slightest change in density of the plate had a huge significance to the tone/exposure of the print.
The first one I bleached back as it was over exposed. The 12×15 was too dull and flat even with selective bleaching.

I do like them though. Van Dyke Browns with some contrast control next week, and some silver gelatine prints while I’m at it.

    Nice… My holiday was not that productive on the whole antiquarian process side of things but i did one decent 10×12 ambrotype and i printed a cyanotype just to see how it came out and the answer was “great”….much better than the slighlty overexposed ambro would have expected to come out…my exposure time is around 4 minutes for the tanner being a foot from the print frame…the glass in my frame is the super cheap 3mm non float glass….i wonder it your glass is perhaps blocking something? 12 minutes would result in a completely mudded up blue mess with my processes

    Hi Gordon, I’m using the contact printer that came with the Hunter Penrose camera, I dont think it coated. Actually my other smaller contact printer gives the same times come to think of it.
    Are you using the traditional cyanotype recipe or the “New Cyanotype” recipe with Ammonium iron(III) oxalate instead?
