Yet another D30 wedding -- I love this camera!

[John & Cindy La Barge]

What type of prints are most of you making for your wedding and portrait work with the d30? Are you having to really work over the images in PS before you print them?
I've done one wedding with the d30 and made dye subs for proofs, but wasn't that impressed. I'm really wanting to use the camera for more than just my event business.
I'd like to do portraits and more wedding with it but I'm not sure what I'm not doing to get the quality I'm looking for. When I print 8x10's dye-subs they just don't look smooth. (a little pixeled) I have a hard time believing printing a 16x20.

thanks, John
