I have purposely picked a picture with some big problems to push myself in using these tools.

The picture is curling and there is a lot of desk/wooden area showing in the background. I did the adjusting as directed and am pleased with the results. 

I brightened the picture using levels. This brought it back to what it really looks like and the true colors.

The stamping tool was the best part. I purposely picked a painting I considered ruined. There's a big blotch of orange outside of the beak line of the flying seagull that I couldn't fix. This fixed it and made it a usable picture. 

I also corrected the green of the grass the standing seagull is on. It had gone outside the lines as well. 

I didn't test out the lasso / moving of words tool, but I like it and can see it's usefulness in the future.

I'm pleased with how it turned out. This is all so useful to know. I can see using it in a few ways I would not have before.
