The S-Curve Adjustment
Here is a really simple technique to enhance a certain type of image. Not all pictures will benefit from this, but those that do, sometimes really do. It's a matter of personal taste too. I'm a fan of the s-curve adjustment, it just takes a little experience to know if it will help an image or not. If you're not sure it takes less than a minute to find out.
The S-Curve makes the darks darker and keeps the highlights bright. It's a great way to improve a 'flat' image.
