Going beyond the standard advice and keyboard shortcuts, we’re going to focus on some more advanced methods for improving the screen capture experience in OS X, including setting a designated folder to save them all into automatically, changing the saved image format itself, taking challenging screen shots with the help of a timer, snapping the cursor, and a nice trick that lets you move around the drawn screen capture box after it’s been set on screen. These 5 tricks will help you to take better screen captures in Mac OS X, and they will apply to the standard methods of taking screenshots, with the exception of the timer which requires a separate feature outside of the normal keyboard shortcuts.
A quick review of the two primary screen shot shortcuts these tips will apply to, for those who are less familiar:
- Command+Shift+3 – Snaps a screen capture of the entire screen(s) and save it to the desktop as a file labeled “Screen Shot” followed by the date
- Command+Shift+4 – Turns the cursor into a selection box that can be drawn on screen to snapshot items in the rectangle, also saves to desktop as a file
- There are actually many other keyboard shortcuts for taking screen shots in OS X but they are really best covered elsewhere since not every one of them will be applicable to the tips here.
1: Create & Set a Designated Screen Shot Folder
defaults write com.apple.screencapture location ~/Pictures/Screenshots/Follow that up with a restart of SystemUIServer for changes to take effect:
killall SystemUIServerTest it out by taking a screen shot, it’ll now save directly to the Screenshots folder instead of the desktop.
2: Change the Screen Shot Image File Format
defaults write com.apple.screencapture type jpg
And again, restart SystemUIServer for JPG to be set as the new file type:
killall SystemUIServerTake a screenshot to confirm. You can also choose GIF, TIF, PDF, or return back to PNG if you want the default setting again. Pick the appropriate format for your needs and this can prevent you from having to batch convert a huge group of images after they’ve been taken.
3: Take Impossible Screen Shots with a Timer
- From Grab, pull down the “Capture” menu and choose “Timed Screen”
screencapture -T 3 osxdaily.jpgReplace “3″ with how ever many seconds you want the timed delay to be.
4: Capture the Mouse Pointer or a Custom Cursor in Screen Captures
- In the Grab app, open “Preferences” and select the desired cursor type”
- Take a screen shot using Grab app to capture the mouse cursor
5: Move the Selection Area from the Original Position
- Command+Shift+4 allows you to take a screenshot with a selection box, but have you ever wanted to move it around after you’ve drawn that selection box? You can.
- Hit Command+Shift+4 to draw the screen shot selection box as usual, then hit and hold Spacebar and click to drag the box
