ObjectiveFlickr is a framework for implementing the Flickr API in Objective-C. ObjectiveFlickr was designed for use in Mac and iPhone applications, but since it was developed for iOS 2.0, it may require some updates to match the current iOS version.
Creating a photograph that gives life to its subject is hard. Once you have done that, proofing and selling your photos should be easy. ShootProof is trying to simplify photography post-production. ShootProof is a web based service that allows photographers to upload, organize, share, and sell photography online. The read/write ShootProof API provides developers access to many of the site's features, including uploading new photos.
