-Forget to level or not level out enough (off a degree or two)
-Cut bits and pieces off planes when shooting them in the air
-Forget to clean the lens
-Forget to alter settings depending on light and motion
-Tend to over/underdo sharpening, color adjustments
-Forget to take my camera with me at ALL
-Forget one little piece of necessary equipment (camera download cable, laptop, battery charger, extra card, etc)
-Forget to pay attention
Considering I've been only doing photography for a year and aviation photography for about six months, I suppose I'm on the right track. A.net is definitely making me get out and learn and try out new angles and techniques. I just can't wait until I can afford a DSLR!
Currently not active in aviation photography or this site. Thank you for your interest.
