Have you ever noticed any purple or green halos along the edges of your subjects in your images? If you have, this purple and green fringeing is also known as chromatic aberration and occurs because the red,green and blue colours in light have different wavelengths and therefore the point of sharp focus occurs at slightly different distances for each.

While many lenses attempt to counteract the issue of fringeing and chromatic aberation, many budget zooms and lenses can't handle it as well. It's therefore very important you know how to control it and remove it once you've loaded your images into your software. In Adobe's Camera RAW interface we're given excellent control of reducing the effects of fringeing within the Lens Corrections tab and in the video below we show you how to go about the task.

For more top digital tips, techniques and advice make sure you check out the August issue of Digital Photo Magazine and you'll be able to read up more about fringeing and chromatic aberation on page 52.
