I'll echo what a few have said, being an "adult onset" hunter. My background was sorta like yours, save for the camera part. I started out being interested in backpacking, then fishing, then put the two together. I had always wanted to hunt but living in areas with next to no public land meant either befriending someone with property or paying to get on a lease. In hindsight it would've been a good idea, but I hadn't ever hunted before so at the time I didn't know if it would be a big waste of money or not.
When we moved to Washington I started with small game and worked up from there. Small game lets you get your feet wet during very liberal seasons. You get to see the killing part, then the work that comes after albeit scaled down. If you decide it's not for you after that, you haven't sank a bunch of money into it.
My first season I hunted grouse and rabbit. Found them both fun to hunt and tasty to eat. Then I started deer hunting the next season. I had been interested in archery at that point, having bought a bow before moving out here from the east coast(I had planned to hunt, but once I discovered that little public land dilemma I decided to put it on hold until I moved out this way. Subsequently I sold the bow before moving out).
I ended up buying a rifle, and then deciding "screw it" and buying another bow as well. I ended up hunting archery my first big game season and I learned a lot. My very first day out I could've filled my tag had I known what I was doing. I had one dead to rights at 15 yards while walking through some timber. It took me until the following season to finally fill my tag, and that season I let a lot of deer walk before I took one.
Believe it or not, it wasn't until 4 years later when I finally shot something other than a target with a rifle(a bear)... and the year after that I took two deer out of state with a rifle, and a buck here with my bow.
When you're out hunting for small game, you'll be taking notes of where you see deer/elk. Where you see sign. Where you see crowds. It all helps later on.
Good luck!
