Snow Leopard nice touch: no more "Picture 1" files

I've always been a fan of ⌘-Shift-4 for taking quick and easy screenshots on my Mac, even with such level-up options as Jing, Skitch, GrabUp and LittleSnapper readily to hand. What I wasn't a fan of, however, was the proliferation of "Picture 1," "Picture 2,"... up to "Picture N" screenshot files on my desktop. Not only was it tricky to figure out which Picture file was which (a task made easier with Quick Look), it was also reasonably likely that at some point I'd overwrite a Picture 1 someplace that I wanted to keep with a brand-new Picture 1 I just snapped and copied off my desktop.

It's certainly not one of the marquee features of Mac OS X 10.6, but there's one little Snow Leopard tweak that's already won my heart: no more Picture 1s! Screenshots to file created via the system key commands (⌘-Shift-3 or -4, add the Control key to capture to the Clipboard instead of to a file) now get a name that's quite a bit more descriptive, including the date and time of the capture. No more file name collisions, no more wondering which Picture is the one you took of that cryptic error message in the middle of the night. Viva Snow!

Eliminate shadows in screen grabs

Sharing screen grabs and screencasts is a great way to show someone exactly how to do something with their Macs. You've got several choices for screencast software (here's a list of posts in our screencast category), but snapping a simple screen grab is much simpler.

Using Apple's Grab application you have a few options:

1. Shift + Command + 3 produces a snapshot of the whole screen
2. Shift + Command + 4 produces a crosshair that you can drag over a specific area of your screen
3. Shift + Command + 4 followed by the space bar turns the crosshair into a camera

Number three will let you grab a single window. The problem is that it includes that window's shadow, which you might not want. Fortunately, MacOSXHints has described how to exclude the shadow. A single line typed in the Terminal will get the job done.

That's great and all, but for some real fun, take a screenshot of a collegue's desktop, move all his desktop icons onto his hard drive, set your screenshot as the desktop image and feign ignorace while he clicks furiously on his "icons." You're welcome.
