Just for fun, I went to the local dog off leash park today and took my camera. Thinking about the position of the sun, I found a spot and settled in on what I hoped was some clean grass to take photos of whatever dogs wandered by me. I soon figured out that many of the dogs would be in an area where my photos would include the fence and parking lot as the background.
Even a cute dog like this needs a better background!
When you start to take photos from a certain spot, remember to stop after a few photos and notice things in your photos that you missed in your initial excitement of capturing a cute dog trotting across the grass. This can save you from going home with photos with a fence and cars in the background and you will have more photos with a rail fence and sky or grass and trees in the background. Sometimes you can stay in the same spot and just turn right or left to locate a much better background for your subject.
