The original materials identified :
- Cellulose acetate negatives (heavily scratched)
- POP prints (faded)
- Silver halide prints (faded)
- The faded prints were recopied using Wratten 47B filter and tungsten light with high contrast film and paper developer (Dektol). This brought out all the tones in the faded original.
- The cellulose acetate film negative base was dissolved in solvents and the extracted pellicle which was free of scratches was used to print the cover photo of the book.
