Paint Amazing Watercolors from Photographs by Henry W. Dixon, hardback published by North Light Books in the USA. Available in the UK, ISBN978-1-60061-123-4, price 18.99 from www.davidandcharles.co.uk
In theory, this is an excellent book for all painters who for one reason or another are unable to paint in situ. There are tricks to learn to translate a photo into a painting. This book covers a range of subjects but for me it does not quite hit the high notes. There are eighteen step-by-step instructions.
