Salut a Tous

le truc a suivre ce sont les sRAW sur tous les nouveaux Eos

.. car ils sont obtenus par binning direct de la matrice CMos !

sur DigitalCameraInfo :

<< DCI: The camera also includes a new sRAW file format. How are these smaller files generated, and are they completely lossless? (smaller = total pixels/4 >>

 

<< Westfall: They are completely lossless. The information we have is somewhat limited. One of the things we do know is that is using a binning technique. That is the reason why it is one-fourth the resolution of the full sensor. It’s not down-sampling like a JPEG file. With that binning technique, that’s how we were able to do it. By keeping the file the same as regular full size RAW, all the image manipulation that can take place with a regular size RAW file can be done with a sRAW. >>

 

c'est 1 truc a obtenir des image exploitables, meme en lumière infime...

avec une taille d'enregistrement divisée par 4 par rapport aux CR2 !
