HOW TO MAKE A “WATERMARK” BRUSH
In previous tutorial, I have explained how to make an action to place a watermark exactly in the center of your image. You can batch edit and watermark hundreds of images at a time with the action. So, why would you want to make a watermarking brush? It is useful for times when you want to customize the watermark, placing it in a more strategic place on the image, make a statement with different colors, and/or change its size easily.
Right click right side of text layer and menu will appear. choose convert to shape.
Go to edit select define brush preset, name it and click ok
To add watermark to photo: Open image in photoshop, ctrl-j to duplicate layer. click create a new layer.
Press D and make sure foreground color chip is black. go to brush tool select “watermark” brush. click on new layer, click once to stamp on image in black. If you prefer the watermark to be less visible, change the flow of the brush to a lower percentage, then stamp it. Stamp size can be changed easily by changing the size of the brush. color can be changed in this way too.
Done. Your new brush should be in the brush sets. and you can stamp your watermark on anything, in any color or position you want! Shapes from the shape menu can also be used, as well as a handwritten signature!
