The new Auto Colour command works alongside Auto Levels and the other image adjustment features available from the 'image> adjustments' menu. As we mentioned, this feature is an absolute godsend for digital photographers since it builds on the auto level command's features and eliminates a huge amount of tedious manual colour adjustment.

As you may know, the auto levels command is used to quickly alter an image's contrast and colour values. It does this by automatically changing the colour values of the entire image proportional to the lightest and darkest pixels. This effectively 'neuetralizes' an image's contrast and colours, making photos shot in poor light conditions look much more presentable. See below for an example of this effect

The one limitation of this feature is that it will not change the overall colour cast of the photo. If the original image had a yellowish tinge, as with our image above, the auto leveled image will also have this (though it will be less pronounced). In previous versions of Photoshop, this often meant that additional manual colour correction was neccessary.

The auto colour feature aims to eliminate this extra step by automatically neutralizing the colour of the image based its shadows, midtones and highlights as compared to Photoshop's default values. This one step process produces extremely natural looking results from poorly lit shots in our experience, removing the yellow colour cast left over from the auto levelling process. See below for an example of this.

As you can see, the right hand (auto coloured) image removes the yellow cast left over from the auto level command performed on the second image.

The auto colour feature is very simple to apply. Just select the image and go to 'image> adjustments> auto colour' to apply the effect (or hit SHIFT+CTRL+B). Note that this command also performs the same steps as the auto level tool, so it is not necessary to use them both. Use auto level if you do not wish to neutralize the colour cast of the image.

More than any other feature mentioned here, the new Autocolour adjustment has made our work with images easier. Much, much easier.
