rendering large images

[siliconbauhaus]

I've been searching on the forum but probably not using the right terms to find what I'm after.

I seem to recall that you lower the IR settings as you increase the size of the final render. Is there a thread that anyone knows of here that explains this?

Each time you double the size of your render you can reduce both the max/min values of the Imap by 1. Is that what you're looking for?
