It's an open question - honestly, I can do it during the scan as well. I turn off the auto-levels anyway ... but sometimes it comes out "graying" the white spaces. If I let it auto-level it kills the pencil marks on it's own, which I find a bit silly. Anyway ... will continue with the WIPs tomorrow .

As for levels - whatever people feel is appropriate, is fine by me. Just want it cleared up is all!
