Another useless debate in photography.

​

A raw file is the result of a in-camera process.  That the process does not take into account some of the settings does not matter.  Then you have loss-less compressed and uncompressed raw.  Add a JPG thumbnail used to preview a raw file...

​

Each manufacturer has its own ways to record the sensor data with biased emphasis on one or more RGBG channels.  Because of that a raw is not fully free of processing and never will be.  Add to that various proprietary changes made by the manufacturers and, yes raw is processed. 

​

Compare a raw file to grounded raw meat if you like.  It is just as unpalatable a slab of raw meat unless you like 'Steak Tartare'.

Why do I almost always think of food???
