Hum.  Pro's and con's.  I don't know that there are any, per se, it's just a
way of storing the values.  Let's see if I can come up with some ;-)

You can't really make tonal adjustments on the low bit justified
data...because there are no gaps between the data...what you would do with
low bit justified data is set the setpoints, and then spread it out evenly
over the entire 16 bit range.  You could do the same with high bit justified
data...but with high bit justified data, it's already spread out so before
doing setpoints, you could do "some" level of tonal moves...not that you'd
want to without setting the setpoints first.

Low bit justified data would occupy a VERY small span of an 8 bit
histogram...where high bit justified data would occupy a region, say it was
12 bit data, then when high bit justifying the 12 bit data, the region would
be 16 times wider (4 bits is 16 times larger)...with 15 gaps in between
every valid data value.

Did that help?
