Adobe Photoshop is an image editing program that allows users to manipulate and enhance photographs. Two of Photoshop's most powerful features are its ability to work with layers and its range of tools that allow users to easily add elements to a photo or remove elements from one. Removing the clouds from a photograph is a simple process as long as it has patches of clear sky that you can work from.
Start Photoshop, then click "File," then "Open" and select the image with the clouds you want to remove. This process works best on photos that do not have many clouds in the sky. A landscape photo whose perfect blue sky is dotted with a few scattered clouds works best for realistic results.
Click "Layer," then "Duplicate Layer." This creates a new layer with the same image, allowing you to manipulate the duplicate image without making permanent changes to the original.
Press "S" on your keyboard or use the mouse to select the "Clone Stamp Tool" from the tool palette. Press the bracket -- [ or ] -- keys on the keyboard to decrease or increase the size of area you're affecting with this tool.
Press and hold down the "Alt" key on your keyboard, then left-click on an area of the image where there is clear sky. This is the part of the image you will "clone" over the clouds to remove them.
Move the cursor over the clouds you want to remove. Press and hold down the left mouse button, then drag the cursor over the cloud to begin removing it. A "+" on the photo indicates the area you are using to cover the cloud. Take care not to clone in any elements other than the clear sky.
Keep using the clone brush until you have covered all the cloudy areas on the photo with clear sky.
