Actually, everything. For starters, it is a 1600 px jpeg (before being resized for posting here). And it is out of focus... totally, across the board. So, what happened?
I was sitting in my local Barnes & Noble cafe, sipping my coffee and reading, when mother nature decided to throw one of her shows when you least expect it. The sky wast changing colors rapidly, leaving no time to run outside and look for a better vantage point, so I grabbed my Canon G10 and pressed it against a second-floor window, trying to eliminate reflections. I quickly checked the settings, noticing my control dial was on one of the two "C" (custom) settings, and moved on to concentrate on avoiding the glass reflections. Except... I juxtaposed the two custom settings in my memory (which happens when you do not use a camera often enough). You see, when I go to a B&N to read, I use my camera as a visual notepad (or a hand-held copier), so C1 setting is set to jpeg, 1600 px, and CLOSE UP! The other setting, C2 is of course, RAW all the way, etc.
Posting this in the beginner section to show that I too make beginner's mistakes more often than I care to admit (even to myself). Feel free to join me in this Hall of Shame with your own examples. All for good fun, of course, as it happens to be the "flavor of the year" on this site as well. Hopefully we can all learn from mistakes too.
