I made a tutorial :) I hope you like it.
>>>
Credit me if you use this!
Program: Photoshop CS2
01 - Duplicate your base and set it to screen.
Change the opacity to 40%, you can make it as light as you want.
It depends on how dark your image is.
02 - Add a selective color layer and set the settings like this:
Reds:
Cyan: -100
Magenta: 0
Yellow: 0
Black: 0
Yellows:
Cyan: -100
Magenta: 0
Yellow: 0
Black: 0
Neutrals:
Cyan: 40
Magenta: 0
Yellow: -30
Black: 0
Now you can add text if you want..
And that's it :) If you're not happy with the end result
you can always play with the settings and opacity's of the layers.
