Improve Your Photos with Better Composition
It's simple...be aware of background objects.
Before you snap the picture observe the background behind your subject. Make sure there aren't trees, bridges or other objects growing out of peoples heads. This can be distracting and ruin what could have been a great picture.
You may have to move your subject or shoot from a lower perspective. Change your point of view it's worth it.
Control the background in your photo. Get it right in camera. Don't fix it in photoshop, fix your composition.
