How to Create Cloud Shapes in Photoshop
You can create any cloud shape in the sky what you want .In this Photoshop tutorial, I will use a Horse photo to define the shape of the cloud. Simply select two reference image into Photoshop and cut the object out of the background using the quick selection tool. Once the shape is roughly selected, then drag it on sky image by using Move Tool. Then it is time to cover clouds over the shape. Here you have to use enough clouds to fill the shape. For this, duplicate the cloud shape many times and move it to cover the different portion of the horse.
To copy clouds, go to ‘select - color range’ and click on the white of the clouds. Then create a new layer and fill the selection with white. This will make a cloud with a transparent background that you can move around the image.
Use a Custom Brush to Define the Edge of Clouds and to fill the few parts of the horse where it is necessary.
After covering the original shape with clouds, use a layer mask to define the edges of the clouds to fit the edges of the shape. To make the new edges of the clouds to look right, use a brush made from same cloud shapes. I will show you how to create the brush in this tutorial.
