In Photoshop CS6, 3D functionality is part of Photoshop Extended. All features in Photoshop Extended are part of Photoshop. Photoshop does not have a separate Extended offering.
You can use the Count tool to count objects in an image. To count objects manually, you click the image with the Count tool and Photoshop tracks the number of clicks. The count number is displayed on the item and in the Count tool options bar. Count numbers are saved when you save a file.
Photoshop can also automatically count multiple selected areas in an image, and record the results in the Measurement Log panel. See Performing a measurement.
A default count group is created when you add count numbers to the image. You can create multiple count groups, each with its own name, marker and label size, and color. When you add count numbers to the image, the currently selected count group is incremented. Click the eye icon to show or hide a count group. Click the folder icon to create a count group, the Delete icon to delete a count group. Choose Rename from the Count Group menu to rename a count group.
To set the color for the count group, click the Color Picker.
Enter a value from 1 to 10, or use the scrubby slider to change the value.
Enter a value from 8 to 72, or use the scrubby slider to change the value.
To move a count marker, move the pointer over the marker or number until the cursor changes to the direction arrows, then drag. (Shift-click to constrain the drag horizontally or vertically.)
Alt-click (Windows) or Option-click (Mac OS) to remove a marker. The total count is updated.
Click Clear in the options bar to reset the count for the currently selected count group to 0.
Counts already recorded in the Measurement Log are not changed by clearing count numbers from the image.
Choose View > Show > Count.
Choose View > Extras, View > Show > All, or View > Show > None.
To record a count to the Measurement Log, you must have Count selected as a measurement data point. Choose Analysis > Select Data Points > Custom and select the Count data point in the Count Tool area.
Use the Photoshop automatic counting feature to count multiple selection areas in an image. Define selection areas using the Magic Wand tool or the Color Range command.
If you are using the Magic Wand tool, increase or decrease the Tolerance option to optimize the selection of the objects you want to count in the image. Deselect the Anti-alias and Contiguous options.
For Color Range, set Fuzziness and Selected Colors to fine-tune the selected areas in the image (see Select a color range).
Photoshop counts the selection areas and enters the number in the Count column in the Measurement Log.
