The photokina is the leading international trade fair of the entire photographic and imaging industry. It offers as the only event worldwide the comprehensive presentation of all visual media, all imaging techniques and all imaging markets - for professionals and for consumers. The spectrum ranges from image acquisition, storage and processing to image transfer and playback. The photokina is understood not only as a revenue driver of the photo and imaging industry, but also as a novelty and trend forum, which significantly shows the convergence and integration of different technologies and product lines. The photokina is divided into five theme worlds: Capture your world - cameras, lenses and equipment, Light up your world - light, flashes and tripods, Share your world - store, connect and transfer, Create your world - input, treatment and processing, Show your world - finishing, printing and presentation. That is why photokina is much more than just photography. It offers worlds for touching, experiencing and immersing and helps to make the fascination imaging tangible. With live photo shoots, video and photography workshops and the photokina action zone it is taken care of a lot of variety and fun. For young photographers and students the photokina academy offers a meeting place to network and interact with professionals and other students of the scene. The highlight of photokina is the prize for the winner of the Cologne Photo Marathon, which takes place prior to the fair. On the whole the organisers welcomed on the 6 days of the fair, from 20.
