Getting To Grips With Adobe Photoshop CS4’s Magic Wand Tool

When I run courses on Photoshop, tools like the magic wand and the clone tools are usually the ones which everyone finds the easiest to start using because they give such immediate results. The Magic Wand is one of three tools in Photoshop which are dedicated to making selections. The Magic Wand works by selecting colours within the image adjacent and similar to any pixel that you click on. Pixels of dissimilar colour act as barriers to selection and so the selection ripples outwards from the point you click on.

Demystifying Histograms In Adobe Photoshop

The Histogram panel in Adobe Photoshop CS4 (Window - Histogram) offers an overview of the tonal range of an image. The histogram is basically a chart which shows how many pixels are present at each luminosity value, with dark pixels on the left and lighter pixels on the right. If no selection is made, the histogram reflects all the pixels in the image. It is also possible to select just part of an image and use the histogram to examine the distribution of pixels just within the selected area. If the image consists of multiple layers, Photoshop displays a pop-up menu which allows you to choose either “Entire Image” or “Selected Layer” to determine which pixels are included in the output shown in the histogram.

As with all of the other selection tools, it can be used to make both new selections and to modify existing selections. To choose the marquee shape you wish to create, simply click on the tool and hold the mouse button down until the flyout menu appears then choose either “Rectangular” or “Elliptical”.
