Just got an email from a big warehouse art supply store. They were showcasing projectors starting at $369... you too can be a hack! My words, but yes from $369 to up to $1200 for a projector that will allow you to manufacture an image that completely short circuits the essential point of making paintings and developing any authentic style. These projectors are completely unnecessary crutches that grant you absolutely no authenticity at all. Yet they are being marketed and sold without shame so I suppose they are being used without shame as well. It is not different in the art process than lip-synching is in music.
