I missed a bit of nuance that others have pointed out: for animals, especially birds, there are some very talented identifiers, who seem like they have the ability to “Enhance! Enhance! Enhance…”, some good examples in topic: Poor quality photo observations from the past have received Research Grade
For plants, where the organism isn’t moving away from the observer, maybe there’s a higher expectation of clean, motion-free photos, and therefore more annoyance on the part of identifiers, me included?
