I take a lot of photos. So many that Aperture is starting to bog down. I was talking with a fellow photographer and he said that he splits his Aperture library every six months. Sounds like a good idea. How do I create a new Aperture library or, better, move a project into a new library?

I've seen your earlier article about using Image Capture to get photos off an iPhone 4 onto my Mac OS X system, but it doesn't seem to work right. Sometimes I hook it up and it just doesn't see the newest photos, as if it's remembering a previous version of my photo library on the iPhone. Is there an alternative?

I find myself in a situation where I want to share a few galleries of photographs with clients, but don't want to send them the originals -- that's my lifeblood as a pro. In the old days, I'd be showing them a contact sheet or proof sheet, but now that it's all digital, I'm a bit stuck. Can I produce a contact sheet within Aperture?

I've used iPhoto for a long time on my iMac and one of its best features is the ability to select a pile of photos and share them with my Facebook friends. I've recently shifted to Aperture and like its additional power and capabilities but can't get it to connect with my Facebook account any more. If it matters, I did set up the Facebook 2-step verification security, as you recommended. Are these related?

Now that I am importing photographs into iPhoto taken by different members of my family, I'd like to be able to see which camera (e.g., which photographer) was responsible for a given picture. I believe that information is stored in the "exif" information, but how do I view that in iPhoto on my Mac?

How can I change the picture on the background of my Mac? I know it's probably easy, but I have no clue.
