Understanding 32 bits image mode

Hi

 

i'm developping a plugin in which higher image quality means higher sound quality.

 

though when i'm in mode 32 bits, colors don't behave the same way as in 8 bits or 16 bits.

 

for example, in 8 bits i have

R = 128;

g = 255;

b = 128;

 

it will not be the same color as in 32 bits:

R = 0.5;

G = 1;

B = 0.5;

 

(in 32 bits, is it much brighter)

 

how come ?

 

how do i do to use 32 bits mode with the same color scheme as in 8 or 16 bits?

 

thanks

 

Jeff

    Because 32 bit/channel is floating point, and gamma 1.0.

    Your 8 bit values are probably gamma 2.2 (or whatever colorspace you are using).
