Contrast, colours, and curves, oh my!
Curves is one of the most powerful tools a photographer has in his or her arsenal. You can do a lot more with curves than you can do with the Levels tool. In fact, most photographers who embrace curves stop using the Levels tool altogether – although until you fully understand what Levels is, what it does, and how to use it, you’ll never be able to get the full potential out of the Curves tool either.
So I figured it was time that we had a very close look at Curves, what they do, and how to use them. Just when I started researching the topic, I discovered that my new friend Matt Greer has an amazing write-up on curves over on his web-site, creatively titled Photoshop Adjustment Layers – Curves.
In fact, his whole blog is worth reading, because he has a series of good Photoshop tips, tricks, and in-depth tutorials that – without being a patronizing git – gives you a gentle introduction along with more in-depth power tips.
My day job, if it can be called that, is being a writer. I've got one book out there so far and it's awesome, so go ahead and buy a copy! It's available from 
In front of you, five hyperactive men with guitars, drums, and microphones. Behind you, five thousand fans. In your hands, a camera... You're going to need more than just a little bit of good luck to pull this one off. That's where this book comes in.
Take a Canon EOS 450D. Attach a Canon 50mm f/1.4 lens. Hit the streets of London. See what happens.
