Errata: The Handmade Silver Gelatin Emulsion Print

Updated: February 20, 2019

I suppose it was too much to hope that there would be no mistakes in my book. I certainly tried to avoid them. Alas, mea culpa and apologies.

I’m starting an errata list here. Please let me know if you find even the smallest mistake. I will give a $25 gift certificate for the Photographers’ Formulary for each one found. Contact me at

My deepest gratitude to Alexander Elkholy, Ian Andvaag, Bernd Dimpfl, and Scott Hellenbach for finding the mistakes.

  • p 150: “Figure 15.17 is a short stack…” should read “Figure 13.17…”
  • p 186: For the salted gelatin, use 2.5 g photographic gelatin (NOT 50 g)
  • p 255 and 256: The titles for Figure 19.1 and 19.7 are swapped. Also, Figure 19.3 should not include the word "Caption."
  • p 295: The recipe has omitted the amount of silver nitrate. It is 5.1 g in 10 ml water, heated to 60C.
  • p 20: Second column, third paragraph: the reference to Figure 3.6 should be to Figure 3.7.
  • p 200: Before adding the silver nitrate solution to the salted gelatin, stir 2 ml (40 drops) 10% solution potassium iodide into the salted gelatin. (See p 120-121 of The Light Farm book in the Blurb preview.)
  • p 220: The ingredient listed as sodium potassium tartare should be sodium potassium tartrate (or alternatively, potassium sodium tartrate, or Rochelle Salt).
  • p 295: The amount of silver nitrate is 5.1 g.

Kit Funderburk's book

Kit Funderburk was one of the original contributors to The Light Farm. A retired Kodak paper engineer, in 2006 and 2007 Kit wrote two short books mostly as a memento for past employees when the last of the Kodak paper mills were shut down and dismantled in 2005. He was well ahead of his time in recognizing that an invaluable piece of photographic history was in danger of memory extinction. History of the Paper Mills at Kodak Park and A Guide to the Surface Characteristics, Kodak Fiber Based Black and White Papers have been treasured members of my library for almost ten years.

As we all know now, chemical photography with its rich and deep history has vanished faster than most of us foresaw. Capturing that history has become ever more imperative. Recognizing this, Kit has written a second edition book combining, and expanding on, his first two books. It is available to read on TLF. I can't recommend it highly enough. So much of what we think of as "classic" B&W prints is wrapped up in the surface characteristics of the base paper. Knowledge of history is important not only for its own sake but also because it informs our present art.

Thank you, Kit! (Again.)
