The market of the photograph is moving quickly. The convergence of photography and video becomes faster. If being able to take a video clip were a gadget in a recent past, Canon 5D Mark II demonstrated advantages to use a large sensor which allows creative lenses and high sensitivities prohibited to silver film. Some movies or series, like " Doctor House" or the new film of Cédric Klapisch, have several scenes filmed with a digital reflex, generally a Canon. If video with a digital reflex is still limited, in particular why it is difficult to have an effective autofocus and noiseless lenses, progress is very fast.
We may notice also the emergence and the simultaneous existence of many types of devices: from professional digital reflexes, hybrid cameras mirror-less but with large sensors and interchangeable lenses, bridges cameras with important zooms, digital compact and at the end of the chain, Smartphones which are now able to take photographs with 5 or 8 million pixels and videos HD.
The camcorders themselves evolve quickly and are refined in several families from pro or semi-pro cameras to video devices with integrated USB connector which allow to put immediately its video on Facebook or the Web.

This technologic convergence brings the photo amateur or professional to re-examine his hobby or his job. The still image can be completed by video sequences. New media like the iPad are supporting a multi-media, instantaneous and polymorphic reading.
