There are a few different ways that you can make something look like a stamp in Photoshop. One way is to use the Clone Stamp tool.
With this tool, you can select an area of an image that you want to copy, and then stamp it onto another area. This works well if you want to create a repeating pattern or design.
Another way to create a stamp-like effect is to use the Layer Mask tool. With this tool, you can select an area of an image and then mask it off from the rest of the image. This is useful if you want to create a more complex design, or if you want to isolate a certain area of an image.
Finally, you can also use the Photocopy filter to create a stamp-like effect. This filter will take an image and make it look like it has been photocopied. This is useful for creating a vintage or retro look.
There are many different ways that you can make something look like a stamp in Photoshop. By using the Clone Stamp tool, the Layer Mask tool, or the Photocopy filter, you can create unique and interesting designs.
