- The first edition was published in 1979 with the title "Modern Photographic Processing"
- C41 was introduced in 1972, yet the book only mentions C-22
- E6 was introduced in 1976, yet the book doesn't mention it
- HC-110 was introduced in 1965, yet the book doesn't mention it
The list could go on and on. And rest assured that Grant knew all these things very well considering his position!
Fact is there is no easy to follow book or path into photochemistry, and a lot of research will have to be replicated by us or will be lost eventually.
