Great question. I am looking forward to reading everyone’s response. This posting will shine a spotlight on users worldwide.
I don’t have any favorite photographers on iNaturalist. I follow friends that I know, all of which live in Ontario. For me, photography is part of using iNat but is not an essential skill. Smartphones and devices like iPads capture excellent images that requires no specialized training to use. With these tools the even most amateur photographers (including myself) can look like a professional. Through use of my device and capturing images for iNat my photography skills have vastly improved.
I like that iNaturalist is accessible to so many groups of people. I might not be able to afford the fanciest camera or lenses on the market, but I feel privileged to have captured some incredible pictures of local wildlife. Overall, I like living vicariously through my friends and other users travel photos. Maps are a feature that I spend a lot of time viewing which has led me to some fabulous locations.
