iPhoto 101: Use two fingers to crop and rotate photos
Here's an interesting feature of iPhoto that I'd never heard of before, courtesy of Mac OS X Hints. While using Edit mode in the app, you can drag two fingers on your MacBook's touchpad (or your Magic Trackpad) to control the various edits with better precision than just dragging around a mouse. You can zoom the crop feature in or out, or even control it manually by dragging two fingers around. And you can rotate the photo in straighten mode just by rotating two fingers around the trackpad. There are more of these little gesture features hidden in Apple's iApps (like a three-finger swipe in iPhoto to move forward/backward through photos), and I'm sure we'll see a lot more of these pop up as we move closer to Lion and beyond. That touch interface is so intuitive and easy that it's no surprise Apple is already implementing it everywhere that it makes sense to do so.
iPhoto 101: How to delete photos
Whether your Mac contains a mechanical hard drive or an SSD, everyone needs more space. We're all used to dumping Finder's trash frequently to reclaim drive space, but what some of you might not know is that when you delete pictures from iPhoto, they remain on your computer since iPhoto has its own trash. If you've never done this, you may have hundreds (or for that matter, thousands) of pictures or videos in iPhoto that are just clogging up your drive. There are two ways to delete the iPhoto trash. One way is to just right click on the word Trash in iPhoto's menu bar, and select Empty Trash. The other, and possibly more telling way, is to single click on the word Trash in the menu bar. You'll be presented with all the unnecessary photos and videos along with the total number held in trash. On the top right is an Empty Trash button that will delete them completely. In both cases, you'll be presented with a warning message asking you if you really want to do this. Click OK, and you'll get back some space. If you've never done this, the amount reclaimed can be dramatic, but if you are in the habit of doing this, you won't get back all that much. I deleted 82 pictures, and my hard drive space increased from 97.23 GB to 97.26 GB. See how much you can get back. [via Lifehacker]
