John is presenting a talk about Photoshop…

For those who are fairly new to post processing of images using software there a number of simple to use but powerful tools for tweaking and correcting digital or scanned photos and making sure they have the maximum visual impact. This talk will look at adjusting the hue, saturation and sharpness of an image as well as those tools which can alter the contrast and brightness of a dull photo. The talk will cater for Photoshop owners and those who would like to know how to get the same results with free software. The talk may also touch very briefly on some of the more advanced techniques commonly used in Photoshop such as removing unwanted detail and creating photomontages.
