Adobe Photoshop CS5 for Photographers : The Ultimate Workshop



Count tool

The count tool is only found in the extended version of Photoshop. Its main use is in areas such as scientific and medical imaging, where it is useful for recording the number of items that appear in a particular image. For example, in the Figure 1 example, I selected the count tool and clicked on all the red/brown pebbles in the picture to count how many there were. You can see how the individual stones have a count number overlaying them and the total count number appears in the count tool Options bar shown in Figure 2.

Figure 1 In this photograph you can see an example of where I used the count tool to count all the individual red/brown pebbles. The count numbers are displayed overlaying the photograph, but these will not show when you print the image.
