Cool photography apps

Some photography-related ipad apps that I have found good. I've not played with any editing apps yet and this is a list of only photo-viewing apps:

1. Guardian Eyewitness: This brings you a new photograph daily with some details and photography tips. They cover very random things all across the world like political events in Sudan, an annual festival in Chile, displaying the poverty in Pakistan and Naomi Campbell on the ramp for an elite fashion event. Overall pretty good.

2 Fotopedia: They have multiple photography apps, the ones I've used are Heritage and Wild Friends. Good thematic collections with useful information to read with every photograph.

3. StuckOnEarth: The concept of embedding images geographically on earth is pretty good. However, the few random photos I've seen till now are not as great as ones in the other apps. I think the description is present in most cases. The purpose is to also help you plan your trip by learning more about places through photos. I really think the idea of the app is awesome, although the implementation can be improved a little.

4. ExploreFlickr: The photos in "Today's explore" are great, but the only drawback is that every photo only has  tags and as a viewer, I have found stud photos with some text more exciting. It gives you some context and the photo doesn't seem to be just another item in the wallpaper collection.

Apart from these, I have also heard that the app for 500px is also one of the best in photography. Doesn't work for me yet since it needs iOS 5 :( BTW, I started using their website from today and it seems like a great hub for all kinds of photography.
