Set focus and exposure for iPhone photos
~MacTips
This Tip uses the built-in Camera app on an iPhone 4S, running iOS 5.1.
When you point your iPhone at something to take a photo it may focus on the wrong thing, or make a subject against a light background too dark.
Learn how single-tap focus and exposure locks can give you better pictures. Tap once on an image to place focus and exposure in that spot. Tap and hold on an image to lock focus and exposure for that shot.
Organize System Preferences in Lion
~MacTips
System Preferences is home to all kinds of very helpful settings, but Lion brings a couple of new features to the app. You can hide Prefs you never use, call up an easy-to-use list of all prefs or display them alphabetically. Here’s how.
Click and hold on the Show All button in the Toolbar to call up a list of all Prefs.
Choose Customize… from that list to select which items to show or hide. Select Organize Alphabetically or Organize by Categories from the View menu.
Quickly print files from within the Finder
~MacWorld, Christopher Breen
Reader Warren Lane seeks a way to quickly print his documents. He writes:
“Is there some way to quickly print a single copy of a file without having to go through a Print dialog box?”
Yes, if you do it in the Finder. Just open System Preferences, choose the Print & Scan (Lion) or Print & Fax (Snow Leopard) preference, select your default printer, and drag it to the desktop. Do this and an alias of your printer appears on the desktop (termed a desktop printer).
When you want to print a quick copy, just drag a file (or more, if you like) on top of the desktop printer and, in short order, your printer gives birth to a printed copy of your document without an intervening print dialog box.
Regrettably, there’s no system-wide command for quickly printing one copy of a document from within an application. A few applications support such a thing—Microsoft Office applications, for example—but as printing is increasingly an “old-school” activity, I wouldn’t hold my breath waiting for other applications to implement such a feature.
Display a list of files in package while in Installer
~MacOSXHints
If you press Command+I while in the OS X Installer, a small window displays, showing the contents of the package about to be installed.
[kirkmc adds: This is great; I don’t know why we haven’t had this submitted before. I tried this with a number of installer packages. In most cases, the window shows the contents of the .pkg from the very first window. However, when checking on the Mac OS X 10.7.3 Combo Updater, clicking the disclosure triangle next to the name of the update in the file list window displayed “The file listing isn’t yet available,” but the file list then showed up a few seconds later. Note that all you can do is view the file list; you can’t copy it.]
Pause animated GIFs in Safari
~MacOSXHints.com
I’m not certain how far back this goes, but pressing the Escape key in Safari 5.1.5 pauses animated GIFs on a web page. I have an older Mac with Safari 3.2.1 and this functionality is not present there. It would be great if there were a single command to stop these GIFs completely, but this is better than nothing.
It’s possible other browsers have a similar capability, but this appears to be a Safari-specifc shortcut. Testing with iCab 4.8, a browser which uses the built-in WebKit frameworks, does not respond to the same command.
[kirkmc adds: Indeed, this does work. There are not hints on the site to that effect. In Firefox, this stops the animation entirely, unlike Safari, where it only pauses the animation. In Chrome and Opera, it has no effect.]
Unzip almost any archive file
~MacWorld
I recently downloaded a zip archive of freely-distributed MP3 files. But when I double-clicked it to decompress it, all I got was a .cpgz file (an archive file in the CPIO format). Double-clicking that file just created the zip file again, and thus I was stuck in an endless loop.
The solution for me was to use the free The Unarchiver, which turns out to be a Swiss army knife for decompressing many obscure types of archives. Opening the file with The Unarchiver decompressed it correctly.
In some cases, The Unarchiver may not work. If this is the case—or if you simply prefer using Terminal—you can try using the unzip command. Just launch Terminal, type unzip, then a space, then drag your archive into the Terminal window and press Return. That will decompress many files that are resistant to other techniques.
