I’ve read many articles saying that using a non-black shadows would give a no reallistic lighting-it’s in Jeremy book too-
But these days I’m watching Toy Story 2 a lot on DVD and I’m freezing the video to study lighting. I notice that the shadows under the bright sun is too bluish where I cannot not beleive they are only tinted by the fill lights.
Any idea? [/B]
I mean actually tinting the shadow colour itself. You’re right, it isn’t technically correct, but it is often used as a quicker way of achieving the effect without having to wrangle extra lights, which of course slows down your render. Every light you add makes your render go slower.
The issue is “realistic lighting”. Toy Story is not realistically lit, no Pixar movie has realistic lighting. There’s all sorts of rim lights with no motivation etc. etc in all their movies but that’s fine because they look beautiful. It’s an aesthetic choice really. Do whatever makes the image look its best.
If we’re being really picky, you shoudn’t blur your depth map shadow to make it soft, that’s “technically wrong” but we all do it, because it’s an efficient solution to a problem.
