I have been fascinated with the macro world since I was very young. I was always looking through microscopes and magnifying glasses and telescopes. I wasn't exactly into biology, it was more the idea of looking at the tiny, intracate structure of things and materials. Most anything you can think of has some sort of order at it's lower levels (except of course the lowest level).
When I got started in photography, I was always somewhat dissapointed at how restricted the cheap cameras I could afford would have. They would have too wide a field of vision or have no option for close-up focusing. It wasn't until I finally got a proper DSLR that I realized how macro photography is actually accomplished. I didn't start with the DSRL, though. I started on a complete whim one day when I had nothing else to do. I found a jeweler's eye and after finding a way to stick it to my phone camera (iPhone 6 at that time), I ran around the house taking pictures of everything I could find that was mildly interesting.
Those first images are of household objects and random things lying around the house. After those first experiments I had a few good photos, some new experience with the concept of macro photography and a hunger for more.
Bees are fascinating creatures. These were found on a tree I passed by every day when biking home from my classes at Tarleton. These photos, while I still think they look interesting, are clearly over-developed. I would definitely handle the editing differently now.
Plants are by far the easiest macro subjects since the barely move, and, on a windy day, they will let you hold them steady. Animals, not so much.
