Afghan protestors firing slingshots and petrol bombs besieged one of the largest US-run military bases in Afghanistan, furious over reports that NATO had set fire to copies of the Koran.

How to Use Photoshop Curves to Correct Exposure and Colour

From the always useful Lightstalking site comes a brief tutorial By on the use of curves in Photoshop. I usually do most of my adjustments using levels but I do know that many people consider curves to be a much more delicate tool that allows for corrections not possible in levels. I do always make extra effort to get correct colour balance and exposure when I shoot so maybe I do not need the refinement of curves.

“In this brief tutorial, we will demonstrate the power of the curves tool in Photoshop to adjust exposure and color. The shot I am using has the potential to be a good photo, but as it was very much a quick grab, there was no time to adjust exposure or white balance. There are may facets to the curves tool, far too many to detail in a brief tutorial such as this, so we will show you the basics of adjusting the curve itself, to get you started on this powerful Photoshop tool.”
