The Count tool allows you to count objects in your image.
You can create and save a Tool Preset for any tool, which will remember settings that you choose for that tool, so you can quickly and easily select different presets and settings for a particular tool. The degree of usefulness of presets varies, depending on the tool.
You can reset any tool back to its default settings by right clicking on the Tool Presets button and select Reset Tool. Take care not to Reset All Tools, unless that is intended.
This shows the result of the count.
You can create different Count Groups, each counting different objects. The currently selected Count Group is shown here, so you can show or hide it, or delete it.
Other Count Groups won't be affected, regarding being hidden or visible.
Show or hide each Count Group. This will affect the currently selected Count Group, as shown in the Count Group box.
Create a new Count Group.
Delete the currently selected Count Group. This will affect the currently selected Count Group, as shown in the Count Group box.
Clear the currently select Count Groups of the count markers. This does not delete the Count Group. It remains available in the Count Group box.
This sets the color for the Markers and Labels of the currently selected Count Group.
Change the size of the Markers for the currently selected Count Group.
Change the size of the Labels for the currently selected Count Group.
Select the Count tool from the Toolbar. Like most of Photoshop's tools the Count tool shares the button with other tools, so it may not be the Count tool that is visible on the button. The default tool is the Eyedropper, but the tool shown will be the last tool used.
Click each time you want to count something. A marker and number are added.
To change the size of the Markers, either click and drag the "scrubby-slider" as shown in the screenshot. Move the cursor over the Marker size, look for the two-way arrow and click and drag. Or enter numbers in the box.
To change the size of the Labels (numbers), either click and drag the "scrubby-slider" as shown in the screenshot. Move the cursor over the Label size, look for the two-way arrow and click and drag. Or enter numbers in the box.
You can change the color of the Markers and Labels. If you have multiple groups, this is useful to distinguish between them.
This will change the color of the currently selected Count Group, so select this first.
Click in the colored box to open the Color Picker.
In the Color Picker, first click on the vertical bar (highlighted in yellow) to select the desired color. The small white triangle near the top indicates where I clicked to select red.
Then click in the large square area to the left of the vertical bar, to select the shade of that color. The green box highlights where I clicked to select that particular shade of red.
When you are happy with the color, click OK.
To rename a Count Group, select it from the Count Group drop-down box.
Then select Rename.
Type your name for the group and click OK.
To add another Count Group, click the Add Count Group button.
If desired, name the group. You can rename later as well.
Click on the delete button to delete the currently selected Count Group. Check this first in the Count Group box.
To clear the markers from the currently selected Count Group, click the Clear button. Check this first in the Count Group box. This does not delete the group.
The Count tool is not particular useful, in my experience, especially in image editing.
