Allocate a time this week to the challenge. It can be a day, it can be ten minutes, as you wish.
During the allocated time, you are allowed to take exactly one photo. No more. No “take a few and see which is best”. No “let’s try that from another angle”. Do everything in your power to get a good photo before you press the shutter. This is a great exercise in spotting problems in the background, dodgy camera settings, and so on. To make it even harder on yourself, try shooting a dynamic subject - changing light, or moving objects. Wait for the right moment and go for it.
Well, I didn't manage to get anything "dynamic" but this was a difficult light situation as it was early in the morning and I was shooting almost directly into the sun. The only post-processing this has had is cropping and a little sharpening.
