| Recording RAW images in general means that the image of the sensor is read out without any camera-internal manipulation. Each of the Images is stored as a single (lossless compressed) DNG Image file which contains the image data plus the Camera Settings you used during shooting - but only as meta data. So if you set a White Balance while shooting in Raw-Mode, this is not directly applied in-camera but will be in the process of "developing" the digital negative. The advantage of raw files is a 12-Bit Color depth compared to 10-Bit in Prores, the disadvantage is a huge volumes of data being recorded. This means that you need a very fast SD-Card and the according setup to transfer, store and backup this data. | Recording RAW images in general means that the image of the sensor is read out without any camera-internal manipulation.
