In my critiques, I mentioned moving left and right to change the background.
These shots were taken behind a local 'fish market'. The first shot was taken first and is an OK shot on it's own...
BUT...the background is boring to me. The next pic is the same bird, on the same pole at the same time...but I moved, I backed up and moved to my right down a dock. I am further and lose detail of the bird, but IMHO, I gain more in the picture.
Changing your perspective by moving slightly can completely change the picture.
Good example of "cropping using your feet". Monnie is going to be discussing this in our next assignment on composition
This could work negatively for you too though. If you were taking a picture for a bird magazine, or other wildlife thing, the background would be distracting. You really have to taylor the shot for what you will be using the photo for.
