- 4 OS X Screenshot Tools
Taking screen captures in OS X is pretty simple and powerful. Today I’ll explain how to use the built-in screen capture functionality, the included application Grab, and a couple of third-party options that offer extra functionality.Built-in OS X Functionality
-
Command + Shift + 3
This keystroke results in a full screenshot and saves the resulting file as a PNG, to your desktop. The file is named with the date and time it was captured. -
Command + Shift + 4
Pressing these keys initially brings up a cross hair on screen that displays the coordinates of the cursor. Click and drag to select the area you want to capture. When you release the mouse button, the capture will be saved to the desktop as previously mentioned. If you press the spacebar while the crosshairs are visible, it changes into a camera icon that you can position over a specific window that you may wish to capture. (That window must be visible when you initiate the keystroke.) During both modes you may hold the Control key at the time of capture. Doing so will save the resulting shot to the clipboard rather than a file on the desktop.
Grab
The Grab application resides in the /Applications/Utilities folder. It’s pretty simplistic, and essentially duplicates the functionality of the built-in OS X feature, albeit, with a couple of small differences. After you’ve taken the screenshot, it is displayed for you to review at which time you must explicitly save it, if it is indeed what you wanted. This also allows you to choose where you’re going to save the file. There’s a Preferences window where you can choose from eight cursor images to be captured in the resulting image. Otherwise, things are pretty much the same. The keystrokes are different, as you’ll see next.
-
Command + Shift + A
This keystroke results in a crosshair on screen that displays the coordinates of the cursor. Click and drag to select the area you want to capture. -
Command + Shift + W
This keystroke allows you to move windows around to select the one you’d like to capture. -
Command + Z
This keystroke results in a full screenshot. -
Command + Shift + Z
This keystroke results in a full screenshot after a 10 second timer elapses.
Skitch
Skitch is developed by the rockstars at Plasq. It’s super powerful and really easy to use. You get to edit size, crop, draw nondestructively, there’s multi-format export, web upload, copy to clipboard, review history and much more. The best part is, it’s 100% free to use!
-
Command + Shift + 5
Pressing this keystroke brings up the (now familiar) crosshairs to select the region of the screen you wish to capture. The image is then opened into Skitch for further editing and use — this is the same for each key combo. -
Command + Shift + 6
This keystroke results in a full screen capture. -
Command + Shift + 7
This keystroke brings up a frame that you can resize to capture a portion of the screen. Initially this may seem to be the same as the crosshair — the difference is, the frame retains its dimensions each time, allowing you to capture uniform shots multiple times.
LittleSnapper
LittleSnapper is developed by RealMac Software. It approaches screenshots from an iPhoto perspective, allowing you to catalog, group, and tag your shots for later use. There’s a built-in browser for grabbing all or a portion of a webpage. The export feature allows you to save a webpage to a PDF file, or any screen capture to multiple image formats. There’s also an editor for tweaking the shots once you’ve captured them. With all this functionality comes a price — it’s $39. There’s also a free trial to see if it’s a good fit for you.
-
Command + Option + 3
This keystroke produces a full screen capture. Once captured, it is loaded into the LittleSnapper gallery for further editing and use — this behavior is consistent with all key combos. -
Command + Shift + Option + 3
Similar to Grab, this gives you a short timer before the full screen image is captured. -
Command + Option + 4
This keystroke gives you the crosshairs to choose the region of the screen to capture. -
Command + Option + 5
This keystroke captures a specific window on screen. At least a portion of the window must be visible before initiating the keystroke.
So depending on your screenshot needs, there’s an app for that (sorry, I couldn’t help myself). The built-in tools are great and produce nice results. I personally opt for Skitch almost daily as it provides the level of control I need, but can see where something like LittleSnapper would be ideal for the designer types. There are plenty of other options out there too, if you want to get your Google on. But hopefully we’ve armed you with a little more knowledge today, to get that perfect screenshot the next time you need one.

- Apple May Be Gunning for Open Source Codecs
The latest indication that Apple is trying to strong-arm publishers to adopt HTML5 and H.264 came today, as Steve Jobs reportedly claimed by email that a patent pool was being assembled to “go after” Ogg Theora and other open source codecs. That news comes just a few weeks before Google is expected to release its VP8 codec as open source, and could come as a big blow to the search giant’s plans to offer an alternative to H.264.The whole thing began today after Hugo Roy, an intern at the Free Software Foundation Europe, published an open letter to Steve Jobs. In that letter he responded to Apple CEO’s “Thoughts On Flash,” in which Jobs wrote that the future of web video would be driven by HTML5 and H.264. Roy argued against Apple’s adoption of H.264 because the codec is not open, but covered by patents and licensed by MPEG LA.
Well Jobs wrote back, warning that open source codecs like Ogg Theora may soon be taken to court for infringing on others’ patents:
“All video codecs are covered by patents. A patent pool is being assembled to go after Theora and other "open source" codecs now. Unfortunately, just because something is open source, it doesn't mean or guarantee that it doesn't infringe on others patents. An open standard is different from being royalty free or open source.”
The email comes as a fight is brewing between major players over the future of web video. For Apple, that future is driven by HTML5 and H.264 encoding, in contrast to Adobe, which is pushing its proprietary Flash player for video playback. However, while most browser makers agree with HTML5 support, not everyone is fully on board with H.264 encoding.
Apple’s Safari, Microsoft’s IE9 and Google’s Chrome all support H.264 encoding for HTML5 video, but the Firefox and Opera web browsers refuse to get behind it, due to potential licensing issues. Even though H.264 licensing body MPEG LA announced in February that it was extending its royalty-free licensing for web video using H.264 through 2016, that was little consolation for Mozilla and others that are committed to supporting open standards.
Google was hoping to stem that divide by making VP8 open source and thus providing a high-quality and open alternative to existing codecs. Google's plans to open-source the codec have been widely expected ever since it announced plans to acquire On2 in August 2009, and speculation intensified after the deal closed.
But without Apple and Microsoft on board, Google may have a tough time getting VP8 adopted by media publishers. And now that Apple’s CEO has confirmed plans for patent infringement suits against Ogg Theora and other open source codecs, Google may have even more issues to deal with.

Переслать - iPad Wi-Fi + 3G Available Today in the U.S.
If you were patient enough to hold out on the wave of iPad releases, and if you specifically wanted to grab a 3G-capable model, then today is probably already clearly marked on your calendar. That’s because it’s April 30th, the official release date of the iPad Wi-Fi + 3G in the U.S.Customers who originally pre-ordered before Apple’s recent cut-off date should expect their iPads to arrive in the mail today, or you can try your luck with retail stores, which are going to be selling the new iPads beginning at 5 p.m.. today. Pre-orders for the Wi-Fi + 3G models were originally lower in volume than those for the WiFi-only version, so it’ll be interesting to see what the response is like at brick-and-mortar retail.
I personally am also very interested in seeing how soon unofficial sales start across the border here in Canada. Following the launch of the original Wi-Fi model, you could buy one the same day at a not completely ridiculous markup, so I predict the same thing this time around. Of course, international iPad users won’t yet be able to get 3G service, since no deals or pricing have been announced with carriers yet, but presumably the devices will work fine with those networks late in May when the Wi-Fi + 3G iPad ships worldwide.
Don’t just show up at the Apple store this morning expecting to pick up a new iPad, though. The launch is scheduled for 5 p.m., and Apple stores across the country are closing down between 4 and 5 specifically to set up for the launch. It’s odd timing, and will no doubt cause some confusion at retail sites in terms of people coming by too early, but Apple must have a reason for not just starting the shopping day with the iPads on the shelves. Whatever the case, expect a lot of confused customers being ushered out the doors at 4 p.m. who are oblivious to the product launch.
The 3G capability is a killer feature for the iPad, in my opinion. Undoubtedly the iPad’s UI is a hit with consumers, as is the user experience in general, but the ability to remain connected while traveling, be it just around town or internationally (as international providers become available) elevates the device from being an amazing entertainment and media player to a lifestyle changer, in terms of both work and play.
Are you getting one? Does your local Apple Store have stock? Is there a lineup? Are you upgrading from a Wi-Fi only model? Let us know your thoughts on all things 3G iPad in the comments.
