I think Alex R. Suggested I look at this wayyyy back when I first got my iPad (which I still love BTW).
Guardian Eyewitness App- One image a day from amazing photographers all over the world. Great source of photography inspiration, as well as culture and just plain old image diversity. There is even a little comment feature from the photographer about the shot, though they are not always super revealing.
If you have an iPad and are a photographer, this is a great little app – it’s FREE and a very clever way to promote their main website. It has my thinking wheels turning. More to come on this.
