Burnam, most of these images are fairly recent. Since 2012 anyway. A time when the semi-pro digital cameras and lenses first started coming on the scene. Figure, a Sony, 24 megapixel, mirrorless with a wide angle zoom lens. A small compact kit costing about $1500 bugs. Modest really. That camera, and the tech behind it, made all the difference.
I get about 2-3 years out of a camera before it's wore out. Usually rolling over 100,000 pics for each one. Never would have happened when I was shooting film. So now I'm like a blind dog in a meat house.
My latest endeavor is capturing native plants. Lots and lots of macro work. I even made some jigs to help with that in the field, as the slightest movement, and narrow depth of field, will screw up a shot. So I take lots and lots.
Never a dull moment. Always another adventure. Keep'em coming.
