There are many aspects of photography that work together to form a good image. If any of these aspects are left out of the picture, you may end up with a sub-optimal photograph. They're all important, but I'm curious which of those aspects are most important — if you had to pick only one, which would it be? As always, feel free to add answers if they're not listed here.
Last week's poll (What Post-Processing Software Do You Use?) shows that a majority of the Epic Edits readers use some form of Photoshop — 49 of 84 votes, or 58%. This is good news for me, because I won't feel so bad for speaking Photoshop terminology during my tutorials.
