Getting Closer to Making some Chloride Bromide (ClBr) Emulsion for Large Format Paper Negatives
I am having a blast working through the process of finding a suitable paper substrate for some hand made paper negatives that I want to use for making large format contact prints. First, I want to acknowledge and thank Denise Ross (www.thelightfarm.com) for her gracious mentoring and help during this journey. A lot of what I am using for a knowledge base on this project comes directly from her new book (The Light Farm, Vol. 1). I reviewed her book recently and I highly recommend it.
I have found a handful of papers that I am going to be testing soon and so now I am mounting a charge to make some emulsion from scratch.
I share exclusive articles and information like this with my darkroom and large format photography newsletter subscribers.
I am going to make some Chloride Bromide (ClBr) emulsion, much like the KodaBromide paper that was discontinued by Kodak in 1999. For my intentions, I think this emulsion formula when matched with the right paper will be a good place to start for making paper negatives. I want an emulsion with good contrast and dynamic range (within reason based on the emulsion capabilities) and a paper that suits my creative objectives. The choice of developer will also have an impact as well. For now, I want to find a smooth paper that will produce nice detail and then I will likely explore paper like Arches Platine that has a tooth to it to create something that is unique and different. The excitement is mounting on my end and I will keep you posted with the next steps.
