| Hi,
|
| I've learned a new word today: Gamma.
|
| It's something with the way monitors show images, but what exactly is it??
| I notice that my scanner software has a gamma adjustment and playing with
| it I noticed that it changes the way the image appear on the screen.
|
| But what exactly is this mysterious gamma thing?
|
| My scanner software defaults to gamma=1.4. It this an optimal value? If
| not, what is a better value?
|
|
| I'd appreciate some scientific facts about this gamma.
|
|
| Thanks,
|
| Tom
