Photoshop is Amazing!

I am amazed at how much can be done in Photoshop - the opportunities and ideas are as endless as the human imagination. I have read 3 or 4 books now and spend countless hours just "playing around" learning by trial and error to see what I can come up with. I've learned the barest basics to "fix" general things in photos, such as levels, contrast, sharpening, etc. I have learned to clone stamp, brush, heal - and even made a custom brush thanks to Violet's tutelage. Photoshop Elements 7 is an amazing tool. No, it's not the full-out $700 Photoshop, but it really can do a LOT of the same things, sometimes in a little bit different way. I also think it's a little more user-friendly than the "big gun" Photoshop. The only thing I have found that I can't do in Elements is record an Action, which is akin to recording a macro in excel. It's a quick and easy way to quickly run through steps that you repeatedly do over and over again. The cool thing is, I can run Actions in Elements (created by others), I just can't create my own. Not a big deal, considering I still really have no idea what I am doing anyway.
Today I was playing with some old flower photos from this past summer when I first got the camera and I stumbled across this "reverse black and white" thing....and I can't seem to figure out how I got to that in the first place, but look what I was able to create! I thought it was pretty darn cool. Now if I could only remember how I did it.....back to the drawing board!
