I am scanning branches for an academic project, and I have a turntable setup (finally). I've gotten a nice Nikon D810 with a Sigma 24mm ART lens. I'm taking 678 photos of the rotating branch from 4 different elevations. The models i come up with now are better than when I was making them with a D7000 with 48 or so photos, but I'm still getting gaps in the models where the branch sections are thin (a few mm in diameter).
My setup has the camera placed about 0.5 meters from the nearest branch section in order to keep everything in focus. I'm trying to avoid the need for manual closeups, as I need to make this a reproducible setup such that field assistants can carry it out. I have the branch set up in front of a green screen, and i process out the green screen prior to RC processing.
Looking at the photos, the thinnest sections are usually 9 pixels wide or so when furthest from the camera, but they're wider when rotated closer to the camera. Having said that, not everything is super sharp due to the distance.
I'm wondering if there might be some settings in RC I could play with that would capture more of these smaller features? Or, any other thoughts for how to improve the results given the constraints?
