Today I went to an exposition of Ansel Adams' photographs.
I have often seen reproductions, posters and images on the web, such as the one below, of this master of photography. 

Whilst I could see that they were perfect monochrome compositions of beautiful landscapes I never knew the amount of detail and the subtlety of those tones. 

I feel invigorated and inspired to improve my own photography and that, I know, is something he would have appreciated.
