The 9th Annual iPhone Photography Awards is open for entries. With categories for Animals, Abstract, Architecture, Children, Flowers, Food, Landscape, Lifestyle, Nature, News/Events, Panorama, People, Portrait, Seasons, Still Life, Sunset, Travel, Trees, and Others means there is something for everyone.
Photos can be taken on any iPhone or iPad and can be edited by any iPhone or iPad app. There is a small entry fee of $3.50 per photograph and the prizes are not going to significantly boost any photography career but it might be fun to enter.
