Fifty Shades Of Gray.

The Fifty Refers to the age of this book collection. 1972.
Long before the age of digital photography. 

Even now there is much to inspire and learn. I still have all my darkroom equipment including the enlarger. I still have my film cameras. One of Russian origin and one of Japanese Origin.

However digital photography is here. All processes can be carried out in light and colour printing on paper is very easy.

Amongst the Fifty Shades of Gray is one book devoted to Colour photography.
