I learned long ago in picture taking when coming upon a photo opportunity to quickly shoot a picture, especially so when people or animals are in the mix. Once I have one in the bank then I can ask myself questions about composition, exposure and aperture settings, and then shoot some additional shots. Above is a good example of that practice paying off.
I was riding my bicycle along a dirt trail at a nearby lake when I noticed this man flying fishing. "Hey, that is a good picture to be had" I thought. I got off my bike, leaned it against a tree then walked down the slope. Well I should say slip and slid down the damp moldy leaf covered slope so as to get a good clear shot without any tree branches in the way. I quickly grabbed a picture and as soon as I clicked the shutter the guy turned around and sloshed his way back to shore. He was done fishing and anymore pictures to be had were gone. I checked the image I had and was pleased with the result for I figured it would take several attempts to get his brilliant fluorescent green line in just the arc I was hoping for.
