Manual of darkroom procedures and techniques

Summary

A search for an official, unabridged audiobook for "Manual of darkroom procedures and techniques" by Paul Jonas across Audible, Google Play Books, Apple Books, Kobo, OverDrive, Hoopla, and Libby did not yield any direct results. The book appears to be an older, specialized technical manual, with search results primarily locating physical print copies from the late 1960s and 1970s sold via used book sites like eBay and sites listing book catalogs like Goodreads and Open Library. Given the nature of the book and the lack of results on major audiobook platforms, it is highly unlikely that an official, unabridged audiobook version is currently available for general purchase or lending.
