8 bits or 12 bits?
Just don't get why 256 is shown up under \"Exposure\", \"Levels\" tab while editing RAW. Is RAW format supposed to be 12 bits, which is 4096? Any advice? Thanks!

Hello
This is because 256 is a scale which people are used to and acceptable as a \"industry standard\"
The problem is that you would have to have to many diffrent scales if it was true value.
0-255 for 8-bit (Tif and jpg files)
0-1023 for 10-bit
0-4095 for 12-bit (Canon / Nikon)
0-16383 for 14-bit
0-65535 for 16-Bit (Phase One camera backs and 16-bit Tif's)
We stick to the 8-bit scale which makes it less confusing this does not mean that we are working with 8bit value instead of the native RAW format bit depth.
We always work with the data in it's native format.0 -

It is 12 bits for channel 😊 which translates to 36bit RGB.0 -

Even Photoshop shows 0-255 when dealing with 16-bit images. It's just a convenient scale.0
