Wide Fields

Different picture types are added to the class of wide fields a. It is depending very much on your point of view. At this phase of my work I put all pictures with a focal length of 200mm and below in the wide field drawer. But this may change one day. I still hope to get the opportunity to shoot some 80mm views with a full size chip. Maybe this will shift my definition of wide fields …
