Every image taken on a digital camera contains some degree of noise, or random variations of pixels. Mostly evident in low light images, noise can affect a photograph in the same way as a bad reception can affect a television set. It's distracting and while impossible to remove completely, can be reduced through the affective use of the Reduce Noise Filter in Photoshop Elements. In this tutorial I'll show you what noise is, and how to tackle it.

The eyedropper tools inside levels have the ability of setting specific values for specific pixels which is ideal when adjusting shadows, midtones and highlights. In the honour of levels we'll look at the eyedroppers and the theory of posterization followed by a full blown creative party as we play with those aforementioned eyedroppers, avoid the party-pooper that lives by the name of colour banding, and perform a very special party trick by transforming the grey eyedropper into a colour replacement tool. Doesn't time fly when you're having fun!!

In this free video tutorial we'll look at how to reduce colour banding, distortion and noise during the sharpening process. To achieve this we've got two options, either use a flat sharpening filter in the RGB colour mode followed by the mysterious fade command or sharpening the lightness channel in Lab. Both techniques are heading in the same direction, so feel free to let me know how they work out for you?
