I would love for someone to explain in " laymans " terms how to do layers in the GIMP software that I'm trying to learn. ( adding and subtracting unwanted objects in a photo )...And can it be used to help " perfect" small or larger imperfections in a photo.?

I just can't figure this out...

what specifically are you trying to do? got any examples?
also, for general GIMP usage, this online book might help.

Well..I need a clue on the basics...plus I read some where that you could use layers to help with sharpening photos, color changes,and just adding and subtracting things from a photo. am I just confused? (as always?) or is this a valid statement?

There's an excellent video tutorial about layers at the bottom of this page at Radiant Vista. It's a Photoshop tutorial but maybe it will be a good primer anyway.

Here's an example fo some self-portraits I did. I adapted the DPC tutorial Touching Up Your Portraits by jonpink to use the GIMP instead of Photoshop.

I started with this original (here resized only for web):

And ended up with this portrait: .

I followed the tutorial fairly closely, adjusting amounts of effects to get the look I wanted. I also added a step where in layers I copied the background and desaturated the copy. I then adjusted the opacity of the desaturated layer until the skin tones were not quite as red.

The next example has a little bit more of an extreme editing to it.
Here's the original, resized for the web:

As you can see, it's quite grainy and waayyy too dark (a lighting experiment gone awry!). I played with a lot of things (levels, curves, brightness and contrast, hue and saturation) until it looked more like the finished product. I then applied the same portrait finishing techniques to it and the flipped the pic so I faced the other way to get this image:.

I hope this gives an idea of what you can do with layers. I know there's a LOT more that can be done using them, but these are the examples I happen to have on hand. If you have any questions about what I did specifically, post them here and I'll try to answer them.

anybody else have any examples they'd like to share and explain using a different type of subject matter?

Don't forget, if you use adjustment layers in Basic editing for Challenges, you have to use them in "normal" mode.
