Gamma Correction on LCD's

[JamesTaylor]

i noticed on a few tutorials regarding gamma correction that the have seemed to be concerned with CRT monitors, and was wondering if exactly the same princples could be applied to LCD monitors??

 

i seem to remember reading somewhere that an LCD's gamma was 1.8 (could be wrong on that??) opposed to 2.2 of a CRT........does this mean that instead of 1 / 2.2 = 0.454 we should work with 1 / 1.8 = 0.555??

 

been meaning to try and clear this up for a few weeks now but been too busy, hopely someone can shed some light on it for me

 

thanks

I'm not sure about the number (1.8), but it makes sense to me.

cheers rick

 

thinking about it, i presume the values of 2.2 in the max preferences also get set to 1.8 aswell?

 

does anyone have any suggestions as to how to find out the gamma value for a particular monitor then?

Linear Color space/Gamma Settings have had my head spinning trying to figure out.

 

Read up on it here for example:

As for finding out your current gamma:

hope this helps! (but will probably confuse even more)
