Official Photoshop Assistance Thread

The title says it all. If you're having trouble with Photoshop, post here and (hopefully) someone will show us a tutorial. 
 
I'll start... 
  
 
If I paste a face on someone else's body, how can I adjust the skin color of the face so it matches the body? The Eyedropper Tool didn't work for me. I couldn't get the perfect match when I adjusted the R G B.

Levels and Curves - preferably as adjustments layers, so you can go back if you fuck it up.      
Mess around with the Reds/Greens/RGBs.

Make sure you have the face layer selected, then play around in Image>Adjustments. If it still doesn't do the job you can try playing around with new layers with different blending modes or you can try playing around with different opacities in the original face layer with the use of Layer>Layer Mask>Reveal All, and then using the brush tool (soft with black and white colour) with different opacity settings in the mask.

For blending faces you can also change the opacity a little bit, just enough so the colors blend, and erase any details on the bottom layer that yu don't want bleeding through.

" @Axxol: With Curves? (Image > Adjustments > Curves...)I've never not been able to match skin tones with curves. Make sure to use all the different channels (Red, Green, Blue, RGB). I thought you spoke about the eyedropper tool in your first post?  "

I used to spend a lot of time on Good-Tutorials and just searched for stuff it really helped me out a lot back in the day. 
But this seems like a cool idea too if it at least gets going well and gets a sticky so it's easier to find 

" @Axxol: you should give an example of what yer working on. it's easier to let people try and tell you what they did then it is to pull one method out of the blue...there are a lot of ways to do it that probably involve multiple steps. "

I guess this would be an appropriate place to ask ; I downloaded GIMP cause I didn't wanna download a crack of photoshop and go through some long process to get it to work, so far its ok I guess, its not very easy to use but I guess that is the nature of programs like this. My question is which is better and does is it worth getting a copy of PS over GIMP? 

Kind of along the same vein as the question above... how do people get photoshop these days? 
  
I had gotten it probably near ten years ago off whatever that predecessor to Kazaa was.  Several computers and a couple hard drives later, I no longer have my cracked photoshop.  It looks like photoshop is still as expensive now as it was back then.  But now there's this Photoshop Elements thing....

I've beem photo shopping since 1996. My way of learning was to photoshop Cindy Crawford's head onto random naked chicks I found on the internet. This was way before google, so this took some considerable skill to pull off.

Here is an old PS image I made.
