Gradient layer tutorial

[kismet72]

I have seen you use gradients for background replacement, I think I get it, but I'm wondering if you have a tutorial for it not just a .psd file that shows how to do it. I also see others post about using a gradient for creating color effects on photos. Do you have a tutorial on how to do this? I don't have a specific example because I'm not sure what photos it would be used on.

Thanks!

Have you browsed the files in here?

There are some gradients there.

Or it's possibly you actually mean Gradient Maps?

Thank you, I will take a look.

Are the gradient maps how the "purple puke" photos are created?

They are one way, yes.
