When you’re starting out in Photoshop, it’s important to be aware of the different merge modes that are available. There are three main merge modes: blend, clone, and merge. Blend mode is the most common and is used when you want to combine two or more images together. It allows you to select a part of one image and use the mouse to drag it over to the part of the other image that you want to merge. Clone mode is used when you want to create a copy of an image. You can select a part of one image and use the mouse to drag it over to the part of the other image that you want to clone. Merge mode is used when you want to combine two or more images into one file. It allows you to select a part of one image and use the mouse wheel or arrow keys to move it around so that all of the images in the merged file are placed in same position on your computer screen.
