Of course! You should always check the background. It can make or break your shot.
Not every photo has a background, but the majority do and when your photo has a background it is as important as the subject itself. Whenever possible, position your subject to be in sync with the background. Make it stand out better, be more noticeable and interesting to look at.
Sometimes we can’t change the background or move the subject but we can move ourselves. And when we move, when you change our angle of view the background changes , too.
We can shift alot or a little to make the subject stand out a little better. We can avoid the pole sticking out of someone’s head or frame the subject.
It’s actually a lot of fun to play with shifting and modifying the background and a good habit
