I want understand the real unit use for The curves mode LAB,Chrominance a and b
citation
In AFP Lab editing is achieved by changing the document's Colour Format to "Lab (16 bit)"
In the manuel, i read this thing
"Input minimum and Input maximum are useful for 32-bit documents with out of range tonal values, but can also be used to fine tune the manipulated tonal range in 8-bit and 16-bit documents:
◦Input minimum—specify, in float, a minimum value to use as tonal input.
◦Input maximum—specify, in float, a maximum value to use as tonal output."
But no,
it' seems -100 + 100, ?
white not -127 + 127,
but for the intern code do you use a float,
with unsigned byte to Float ?...
I want just have a " good understanding.
We found many range on the net -60 +600,
I hope have an answerHave a good day
