When you're touching up your photos, do you find that you seem to subconsciously take photos that have variations of the same color? Like....year after year you gravitate towards it without even realizing it?
For one though, I'd try using the same picture while editing it with different filters. I find it enjoyable to see the image from different perspectives because it is somehow my way of experimenting with my work.
I think that it's largely unconscious. People touch up photos until they 'look right', often times without any consideration for why they are doing what they do, or why it works. I don't think that this is a bad method necessarily, but I like knowing the theory and the reasons behind why I'm doing what I'm doing to a certain image.
