curves mode LAB,Chrominance a and b real unit

Recommended Posts

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

i found

 

On Windows, version:

it is necessary to use the range o, xxx to 0,9999.  Coma in Azerty , no point

normalized range between 0 1
 

And not -127 + 127

We should NOT  pay attention to the propositions that appear positive or negative integers between 0 and 100, with the Mouse Wheel
 

Whenever this serves,
