I have this debate going on in my head about the title of the challenge Abstract Thursday. Should it be Abstract or Abstracted? As I understand it, an abstract image is one that refers only to itself and does not refer to the 'real' world. So a photograph taken from an obtuse angle or showing a minute detail is not abstract but abstraction, as it merely highlights parts of the subject we may otherwise not have noticed. It could be said that a photograph that is heavily manipulated beyond recognition is an abstract image as it no longer relates to the original subject. However the problem for photography is that the original subject is always the light as without the light, with digital or 'wet' photography, we don't have a photograph (photo = light, graph=representation by means of lines). Ok give the camera to Malevich and we would possibly have the first supremacist photograph. Now the problem with the word abstraction in figurative imagery is that everything is abstracted as we would never be able to photograph the whole of the reality we are confronted with.... It is at this point that MrsW would interject with the incisive statement "shut up". 
So one for Abstract Thursday with the actual branch in extras, although not all of the actual branch, or the tree, or the field, or....... ;-)
