Ok, can somebody explain how to correctly calibrate my monitor...

Images can look different on different computer screens. The colors and tones may be different on my computer screen than yours. Color difference may be to your computer not the scanner. Either way, I don't think the problem is perfectly solvable.

Matching the tones between what is on the computer screen and what is printed on the computer printer is a years old problem. They're regularly different and computer programmers have long worked on trying to solve that. For most of us the difference is no concern, but if you're a book publisher, advertising professional or artist it can be a big deal.

Also, is there a 'correct' brightness setting to your or my computer screen. I change the brightness level on mine as often as I do the volume.

Duly note that if you inform me that it's 5, I'll set it to 6 because I don't follow the rules. And that's why the babes love me.
