While in a "desert" in northern Denmark years ago I was just ready to photograph this Norwegian bass player on my 50mm when some people walked into my shot way in the back. I was shooting Polapan B/W slide film so I wasn't thinking Photoshop. My solution was to change to 20mm and move in close to hide the people in the back. I really like the perspective it gave the shot and it also brought in more of the great "desert". This is a technique I still use in stressed situations today. My philosophy is to try to fix it all in camera and not think SO MUCH what can be done afterwards!
