I'm a little bored so here it goes. Every once in awhile we all have to laugh at ourselves for the mistakes we make and I made a good one the other day while down by the bay photographing the wildlife. I'd been set up to take pics with my largest telephoto lens so I was using the tripod. When I decided I'd taken enough pics with that I switched over to a smaller tele lens that I'd just bought and started taking handheld pics. After a few minutes of changing my cameras settings and waiting for a good shot, one finally presented itself and I took a pic but something was terribly wrong. I took a few more and I was puzzled as to why it was when I hit the shutter release I didn't hear anything but after several seconds I finally heard the click. I was sure I'd put the camera on the right settings and I started to think there was something wrong with the new lens (NOOOO, NOT MY NEW LENS) or the camera itself and I started getting a little stressed over it. Then it dawned on me and as many of you probably guessed, the camera's timer was on. I rarely use it and had used it just minutes before when taking pics with the tripod (didn't have my remote shutter release with me, oops!) and I'd totally forgot I'd used the timer. I'd had it set to 2 seconds, not the ten that it was taking for the shutter to release so that slowed me down a little in spotting the problem and I still don't know how the setting changed. I'm still baffled about that. Oh, well, I laugh at it all now. Have any "derp" moments in photography that you'd like to share or am I the Lone Ranger of mistakes in photography?
