Have you ever taken a photo with your iPhone and found distracting background elements that ruined the shot? Now you can salvage some of those pictures with this simple technique. While viewing the photo you wish to crop, use your fingers on the iPhone’s screen to zoom in as much as necessary to eliminate the undesirable background item(s). Then do a screen capture by clicking the on/off button while holding down the Home button. Your new screen capture — the cropped photo you wanted — has now been saved to your photo collecton! You’re all set to email your modified photo to friends, blog it, etc. Of course, this trick can result in too much detail loss if you zoom too much, but for quick cropping without a photo editor, this approach is hard to beat.
