I'm updating my page with a new category called "squared." For the past few years, I've been deliberately shooting my personal photos in square mode, on both my iPhone and my cameras. It's incredibly freeing and challenging at the same time.
By making square mode my default setting, I'm forced to focus on the subject and work the scene. I won’t let me just take one shot and be done with it. I have to think about how to best capture the moment in a square frame.
I've also made myself use a single focal length for the same reasons. This forces me to get creative with my compositions. I can't just zoom in or out to get the shot I want. I have to work with what I have.
I encourage you to try shooting in square mode. You might be surprised at what you can create.
