In computational terms, a low resolution version of an image is almost by definition ‘simpler’, with fewer colours and details intact, but it seems like it would be much harder to do a convincing 1:1 replication of it in a painting compared to recreating a ‘clean’ HD version.
Or am I way off the mark? 😆 I’m not a painter, obviously. Seems like getting all of those weird JPEG artefacts right would be something of a novel skill for a traditional painter (or even a digital painter, for that matter).
it would depend on the style that the artist would chose to use.
if they’re going for realism, then, maybe.
But impressionism, surrealism, expressionism. anything abstract…? won’t really matter.
