Adox Baryta Paper Initial Response to Silver Gelatin Emulsion Testing

December 17, 2015  •  2 Comments

I am continuing to test the Adox Baryta paper for its response and behavior to coating it with silver gelatin emulsion.  In these photos, you can see the paper curl after it was coated and hung (top photo), then after it had dried for about an hour (middle photo), and then I placed it under glass in the bottom photo to see how well it would flatten over time.  

My only objective right now is to learn the behavior and response of the paper after it is coated with silver gelatin emulsion.  I am keeping good notes as I go so that I can make an informed decision about the paper in regards to its suitability to being a paper negative in my 8x10 view camera.  

My initial reaction is that this paper will most likely be a lot of work to get it to lay flat as a paper negative.  It is likely more suitable for a contact print, but I need a little more time and experience to know for sure.  The more that I explore papers as a negative medium, glass plates are beginning to appeal more and more to me.  It really is about trading off one set of challenges for another.  I just have to find the set of challenges that I prefer most.

According to the information provided on the Freestyle website: "Adox Baryta is a pure, uncoated, baryta base paper to be coated with liquid emulsions or used for alternative processes. This is a heavy weight paper made of the highest photographic quality paper. The very fine brushed paper fibers will not be visible in your image. Adox Baryta produces a glossy finish. This paper prevents bleeding, making brush strokes very accentuated."

This probably is a dumb question but what about sizing the paper before coating it.

The thing about the emulsion coating is that the gelatin coating shrinks as it dries causing the curls. At Kodak we would treat the gelatin AND the reverse side of the paper to stop the shrinkage. Perhaps a first coating on the back of non sensitized gelatin then the sensitized gelatin on the front would help?
