Would you mind pointing any of us to ANY electro-optical imaging sensor
which actually is capable of producing 16-32 bits per channel? Real
bits, please, not a lower 3 or 4 bits of noise - we don't want to
degenerate this to "why doesn't the Nikon scanner range achieve its 4.2
dynamic range specification"! I asked yesterday but you haven't
produced any info. Similarly with the "human vision studies" that you
Without raw data with a dynamic range which exceeds 16 bits per channel
there is absolutely NO REASON WHATSOEVER for any software package to
provide more than that depth of processing. Without a visual system
that is capable of distinguishing more than 8-bits per channel there is
NO REASON to increase output dynamic range beyond that. What can be,
and is, discussed is where the transition from hi to low dynamic range
optimally occurs in any given workflow.
There may well be reasons for increasing the functionality of PS
operations to 16bits per channel - as has been discussed many times -
but, so far, anything other than the minimum of what you are asking for
has not been justified.
I am interested in reading solid justifications for more than 16 bits,
because the arguments that have been presented to date on this thread
simply don't stand up to any level of examination.
