it makes sense that louis tries his hand at being an artist, and that attempt a symbol of profound hope! but he also happened to pick the artform most prohibitive to him as a vampire (photography requires light and patience, whereas he’s always outrunning the sun.) and he takes photos of humans that he cannot get emotionally close to (the photo he takes of armand is notably the only one an art dealer gets a lil frisson off of.) he completely stacks the deck against himself, putting himself in a position to reaffirm his prior belief that vampirism is a curse and a limitation.

when he realizes his art isn’t great he quits. but if he had waited for cameras to improve, or taken photos of fellow vampires, (and fwiw i think there was a post floating around about how if louis just ate more, things might be easier lolol) or just been content to suck at it for a while, there’s no reason why he couldn’t have continued (lord knows other vampires are out there being bad and weird at whatever they’re making, in part bc they’re v much out of step with the culture they’re attempting to contribute to. and louis actually seems a great deal more clued in to the zeitgeist based on what he says to claudia about the parisian modern art scene, and even up to 2022 where he knows what essencefest is like my girl still knows whats what more or less.)

i think louis stops not only bc its painful and frustrating to not be able to practice this artform the way he wants to, but bc he cannot deal with the idea that he isn’t Creating Value or contributing, he would just be enjoying himself.
