Capturing a screenshot on OS X is something that I use on an incredibly regular basis. It's super useful to get an image of a website or an image or even just a part of an image. This makes it a lot easier to share ideas with others.
So how to do it? Use keyboard commands! When buttons are connected by a + sign that means that you push all of those buttons at the same time.Command+Shift+3
(capture whole screen) this captures an image of the whole screen and saves it to your desktop. If you use two screens it will save one image for each screen.Command+Shift+4
(capture selected area) This creates crosshairs on the screen. Click and drag to create a rectangle that you want to save. Image is saved to desktop. This is by far my favorite of all of these tools. This is pretty much all I use for OS X.Command+Shift+4
then hit space bar
(capture window) This highlights a window. Hover your mouse over a window and click to save an image of that window.
If you want to save that image to the clipboard
instead, use Control instead of Command
. So saving the desktop to the clipboard is Control+Shift+3, saving an area is Control+Shift+4 and saving a window is Control+Shift+4 then space bar
If you're using Leopard or later, you can modify the capture area you're highlighting with Command+Shift+4
Here are those modifiers:
Space bar - move whole selection
Shift - resize one side of your selection
Option - resize rectangle around the center point
Another option is to use the Grab
application that comes with OS X in the Utilities folder. The functions are pretty much the same except for a timer option that grabs the whole screen after 10 seconds.Even better than OS X
My favorite non-native app is Skitch.
It is very powerful for basic screen capturing as well as adding some quick notes, rectangles, and arrows. It's so great and saves a lot of time. To export images from it, just hit Command+E.Extra Stuff - Capturing Long Web Pages
Sometimes you want to capture a web page, but only a little bit is on the screen at once. I use an extension in Firefox called Abduction
or Screen Capture (by Google)
