Re: Organizational practices with Ps files questions

Too simple a topic? If this is very basic issue for Ae, does anyone know where it's covered? I always look in the documentation first, and check online topics, but some things are hard to find unless you know just the right search terms.

I'm also curious if there's any significant difference between an image with a high dpi or one at 72 at a larger scale. I know Ae ignores dpi and that all video is 72, but an image at 600 dpi behaves more like one at 72 that's several times larger in dimension.
Is it better to stick with 72 and scale them large enough for the intended use, or is mixing different sizes and matching irrelevant, and the only thing that needs to be addressed is that the image is large enough to work at the scale desired without pixelating?
