Today, 19/02/10, Adobe Photoshop is 20 years old. Photoshop has remained successful for the whole 20 years. It started as a black and white image editing program and now it has grown to a multi-product franchise with many different products in the Adobe family. As the years have progress Photoshop has develop new features with every new release and each time the interface get even better and more refined.

Over at the photoshopuser.com you can find details of an event which will take place to pay homage to this program. I believe Adobe are putting on an event to celebrate the 20 years since the first release of Photoshop 1.0.

When you take Photographs outdoors, the weather can be misty, cloudy and hazy which can have a dull effect on your Photographs. You can try manually adjusting the contrast, brightness and gamma of the image, but this can take some time to tweak. A quick method of fixing the contrast in Photo is to use the Auto Contrast feature. The auto contrast works by adjusting shadows and highlights values in an image and then set the darkest and lightest pixels to pure black or pure white. This makes the highlights appear lighter and shadows darker and improves the appearance of your photographs.

To use the Auto contrast feature, follow the steps below.

1. Open up an image you wish to edit in Photoshop. To quickly auto up an image, checkout quick tip 3.

2. Then select Image > Auto Contrast if you are using Photoshop CS4. If you are using CS3 you may have to select Image > Adjustments > Auto Contrast.
