Capture One Workflow 8/14/16 Bit
Hie there,
I have a question just for understanding. When I convert a RAW file, the original image data has e.g. 16 Bits per Color. Now, when Capture One converts the image for doing all the adjustments, this is done based on an image which is 8 Bits per Color. Aas far as I know all the preview images generated by Capture One are just JPGs.
So I am loosing 8 Bits (which is 50%) per Color dynamic range during adjustment process.
This means that I have a high end digital back, but I use just JPG dynamic range for preparing all the adjustments. For example, all the modifications on a Luma curve, exposure and contrast control is (visually) verified on 8 Bit range. Finally, when converting the original RAW into 16 Bis Photoshop file, everything is fine again.
Now my question: How does this fact influence all the adjustments within Capute One? Or, in other words, how does this fact that I do all adjustments on 8 Bits influence the conversion on 16 Bits (since I don not have access to 50% of the dynamic range)? Visual control = 8 Bits -> RAW development 16 Bits.
Are the lower 8 Bits simply cut off, or what?
By the way, I beleive that all other RAW converters do the same.. 😡

P.S.: I know that Apple has problems with 16 Bits per Color color depth. But that's not the point, there are other options.

All internal workings of CO are done in 16 bit, always. Also if you choose to output a 8 bit file. The displayed result in the Viewer is indeed 8 bit, but everything calculated as 16 bit.
Also, 8 bit and 16 bit cannot be used to describe a sensors dynamic range. See bit-depth more as a increase of steps in a given space, and not an increase of space.
Remember 8 bit are 256 steps (2^8), and 16 bit are 65536 (2^16), so it does not scale linearly.0
