In all honesty this could be any Rudbeckia. There are just so many that look alike and this was in a public garden. Who can know?

They do photograph well.

One of my tips when doing the magnifying glass/box camera trick is to seek out shapes that are large, simple and repetitive. It’s especially helpful if there are lots in a cluster like in this shot and the last because then it doesn’t matter if your focus is exactly where you planned for it to be. If you’re striving to photograph a single subject, chances are good that it won’t be in focus. I carry a retractable measuring tape to check the distance but it’s still mostly a guess.
