What’s the optimal viewing time for an artwork?
Less than 5 seconds.
Any more than that and you absolutely have to commit to it being on your wall for at least a year.
And what’s the optimal size to view an artwork?
Less than 2 inches.
Any more than that and you absolutely have to commit to a full size print on paper.
It’s like music. You either listen to only the first few seconds of a song, or you listen to it every day for at least a year. There’s just no middle ground.
