If you own a iPhone, then you are probably taking a lot of photos. While iPhone does have its built-in features for managing and editing photos, a lot of us like to use apps. Here is a list of free photo editing and management apps for your iPhone.
This app lets you transform your photos by applying cool retro effects to them. Pixlr-o-matic offers a wealth of filters and lighting options in a strip along the bottom as well as a selection of borders. You can either take photos using your device's camera, or apply the effects to an existing image.
#2. Photosynth - Capture your world in 3D
Microsoft's Photosynth app for iPhone (oddly, it's not available for Windows Phone 7) lets you create seamless, 360-degree panoramas from multiple photos. Just press 'start' and rotate slowly on the spot to capture and stitch together a series of shots. You can add your panoramas to Bing Maps and explore other users' efforts.
Flock groups together your photos with those of your friends and family to create a shared online album of a particular event. It scans your photos as you take them, and displays them with your Facebook friends' photos taken at the same time or in the same place, with the same people in them. You can set individual photos to private if you don't want to share them.
With Pixengo, you can add 30-second voice messages and ambient sounds to your photos to add atmosphere to them and bring them to life. The app works on new photos, as well as old images saved in your gallery. You can share your 'audio photos' with friends on Twitter, Facebook and email.
Augmented-reality app Blippar uses your phone's camera to recognise real-world items such as posters, newspaper adverts and food products. The app then overlays the object with games, videos and web links. Cadbury is currently offering Blippar content via the packaging of its chocolate bars.
#6. TouchRetouch Free
Forget messing around with fiddly editing tools; TouchRetouch Free lets you remove unwanted elements from photos using your finger. Just select the item you want to erase and press Go. Usefully, the app includes unlimited Undo actions in case you've eradicated something important.
