High Dynamic Range Photographs

Pescadero, California (Roberto Pieraccini)

I discovered High Dynamic Range (HDR) photography recently. The idea is to give pictures a higher  range of  light intensity between the lightest and darkest areas of an image. Standard photography allows for a low range of luminosity--lower than the human eye--so if you expose for a luminous sky, the landscape becomes too dark, and if you expose for the landscape, the sky becomes overexposed. The solution consists in shooting two or more identical pictures with different exposure, say one for the sky and one for the landscape, and then merge them.  The result can be pleasing for the eye...sometimes cheesy  ... the art, in my opinion, consists in going for the former while avoiding the latter ...
