One adjustment challenge!
I wanted to try and process one of my photos using only one type of adjustment.
It became a bit of a challenge, and I used only this one type of adjustment to process the photo. No other tool was used. I recorded the whole process and then I added some more description so the video might be useful for somebody and treated as a tutorial.
The before and after you can see on my page:

Curves would probably be my choice if I could only use one tool as you can do both tone and color correcting with it. It also allows more precise corrections than levels.
