In collage you're doing it in stages so you're not actually doing it right there. You first of all draw it on the paper, then you cut it up, then you paste it down, then you change it, then you shove it about, then you may paint bits of it over, so actually you're not making the picture there and then, you're making it through a process, so it's not so spontaneous.
