The small and simple things can affect a perfect picture so don’t ignore the small things.
Always be sure to check what is behind your main subject. One small object like a garbage can in the background of a perfect picture can make all the difference. And of course with technology things like this can be removed but why spend time on that when it can be avoided altogether?
Always pay attention to your DSLR’s setting for clear pictures and better focus. Always check your auto focus mode and auto focus point. Also always be sure and check your settings. You might have it on a previous days setting which might be totally different than what you might need today.
The smallest things add up and can create the most amazing photographs.
