Use the Camera from Lock Screen in iOS 5

Yet another great feature of iOS 5 is the instant camera access from your lock screen. This lets you quickly pull out your iPhone (or iPad and iPod touch of course) and take pictures without having to Unlock the iPhone or clicking on the camera app. Here’s how to do this.

From the iOS 5 Lock Screen:

• Double-tap on the Home button, a camera icon will appear next to the Unlock slider
• Tap on the Camera for immediate camera access

Once you are in the camera app, you can use the volume up button as a shutter to take pictures. Yet another reason to upgrade to iOS 5 if you haven’t done so already.
