Using the Photoshop Clone tool.

When your work needs attention to detail and careful retouching, improve your images manually, down to the pixel, with the Clone Stamp tool. Erase unwanted items from your canvas like they were never there. 

If you need to retouch a specific layer, or you want your Clone Stamp to capture its painting texture from a single layer only, you can do that. Or you can sample from all layers. Simply select the layers you want to edit while holding down Command (Mac) or Control (Windows), before getting started.

The Clone Stamp uses a sample you define yourself, and then you can adjust the size of the brush you use to paint with that sample from the options bar. It’s intuitive and gives you greater control over your work. 

With the Flow and Opacity settings in the options bar, you can control the intensity of your retouching. Flow simulates the process of building up layers of ink on paper, while Opacity can give your patterns a lighter touch. 

When you’re working with portrait photography, often you want your subject looking pristine — the Clone Stamp and other tools like the Healing Brush can help you remove stray hairs, fix that pimple on picture day, and do other touch-ups. 

An awkward-looking object taking up the frame, like a frisbee flying through your perfect empty beachscape? No problem. With the Clone Stamp tool, you can paint over objects that are taking up space in your compositions.

While the Clone Stamp tool can hide items, it can also help you clone different elements of your work that you want to replicate. This can be handy for certain graphic design projects or a repetitive task that could use some finesse.
