M11 Monochrom bit depth

Hi, 

Anybody that can explain me the difference of the 14bit color depth in the M11 (converted to B&W in PS) and M11M? Is there a practical difference in terms of grey tones (screen& print)?

Best,

Marc

M11 you have 14 bits to represent  red green blue value, M11m you have 14bits to represent a tone, thus far more values available to represent a tone, resulting in that smoother tonal transition you’ll see in a monochrom image

Sort of is my guess. We don't have technology to view or print that level of subtlety, our eyes are also way short of appreciating it too. It does however mean that as we stretch files containing data, the level of resolution is so high that it takes much more manipulation before areas of the data become obviously discontinuous. Having said that, it's not often I can manipulate an M11 or fuji x100vi file that the limitation is the data, it's always lack of captured data, ie blown highlights or banding artefacts which are the limiting factor. The former of these is no different in film emulsion of course, if you've not recorded data it's always going to be a hole!
