With the release of the Hasselblad H3DII-50 Multi-Shot camera yesterday, there have been a lot of questions about what exactly multi-shot technology is all about.  Here's a quick video showing how the sensor is moved, or stepped, in the process of taking 4 or 16 shots- in a process similar to HDR processing, you're taking several shots and gathering a leveraged range of information, in this case resolution, and then assembling the separate shots to produce one vastly superior image. 
 

Think scanners.  On the sampling axis, that is, the actual scanner path, if you want to double the resolution you just take a sample twice as many times.  Same deal. 
 

Stay tuned for more about this camera and the technology behind it...  when we talk to Christian Paulsen of Hasselblad!
