[Alt-photo] Re: toning kallitypes

[Sandy King]

The toner can be reused, but each time you use it it becomes weaker, and toning takes longer. I would recommend instead of reusing it you use one-shot and discard. This will give greater consistency, and may actually be more efficient in terms of cost. To use one-shot you will need a flat bottom tray. How much you will need to tone a print depends on the image.  For an 8X10 print try about 25 ml of the toner solution. If the shadows don't tone add more of the solution. Images with a lot of shadow density need more toner than those that have mainly upper mid-tone and highlights.

I have an article on kallitype at http://www.alternativephotography.com/wp/processes/kallitypes/the-kallitype-process
There is some information on toning that you may find interesting.

I've read a number of books on the subject but one topic that is hinted at but I haven't seen spelled out is long term care/use of the toner solution you make.

So it would be great if I can use the toner solution on a large # of prints. For example, Jill Enfield recommends a mixture of 1 liter distilled water, 5g citric acid and 5ml platinum - any thoughts on how many prints at 8x10 this should tone?
