Eureka!

what was that "aha!" Moment or bit of information that caused drastic improvement in your photos. Although my photos aren't where I want them to be, my "aha" moment was when I realized that shooting during the golden hour was a good idea and I finally started to go easy on the saturation and contrast sliders.

What has caused the most improvement for you all?

The moment I really started to understand and see how the lighting had an effect on the photo. Probably my biggest leap (at least in my mind) is when I learned how to add lighting to existing light to make a more flattering photo.
