My day job is teaching engineering mechanics at UWM
I started taking pictures after I noticed some birds as I walked though Estabrook Park for exercise.
I used a not-very-fancy and seven-year-old Fujifilm FinePix HS50EXR 16-megapixel digital camera with a nice 42x (24-1000mm) manually-operated optical zoom, automatic focus, and image stabilization. It worked great for over a year, and I took at least 20,000 pictures on it, but I was a little disappointed in the first owl pictures, so I finally upgraded to a Fujifilm X-T4 with a Fujinon XF100-400mm F4.5-5.6 R LM OIS WR lens. It took me a few weeks to get the hang of it, but I’m much happier with the pictures from the second owl encounter, and I still have plenty to learn.
For all the other stuff, I just ask Dr. Google. The ability to search for similar images is handy sometimes.
