In Photoshop CS6, there are a few ways to make a watermark in the program. One way is to use the “Marker” tool, which is located in the “Tools” menu. The “Marker” tool can be used to create a simple watermark on a document or image. To use the “Marker” tool, first click on the icon in the bottom left corner of the screen and then select “Marker.” The “Marker” tool will default to a black marker. To make your watermark more visible, you can change its color by clicking on its color button and then selecting one of Photoshop’s six colors. You can also change its size by clicking on its size button and then selecting one of Photoshop’s three sizes.
