Adobe Photoshop CS3 Tutorial: Advanced Black and White Conversion

In this tutorial, we will convert an RGB image to Black and White using Photoshop CS3’s new improved Black and White features.

This is much more sophisticated than the Black and White conversion found in older versions of Photoshop, and will allow you to increase or decrease the levels of black and white for a particular colour.

It is also a great way to create duotone effects.1Open a coloured photograph of your choice in Photoshop CS3.

2From the Image menu, select Adjustments > Black & White

4If you just want Photoshop to convert the image using its own settings, click the “Auto” button. But for this tutorial, we will create our own custom settings. Drag the “Blues” slider towards the left to make the blue tones in the image darken. This will create a darker sky with more pronounced cloud contrast. this totally changes the image’s mood.

6If you want to find out the colour of a particular part of the image (in this case, the bricks on the church) mouse over the image. The cursor will change to an eyedropper. Click once in the church and notice how the yellow slider becomes active: the numeric value is highlighted, and a bold black outline appears around the yellow colour chip as shown below.

7You can also click and hold down the mouse to reveal the sliders inside the image itself. The eyedropper cursor will change to a hand icon with arrows at each side.
