If you want to take a picture with your computer and then edit it in Photoshop, there are a few things you need to do first. First, open up Photoshop and go to File > New. This will open up the New Document window. Next, find the photo you want to use and drag it into the New Document window. Now, you need to decide what size you want your photo to be. Photoshop offers a variety of sizes, so choose one that will fit well on your screen. Once you have chosen the size, click on the “Resize Image” button located in the toolbar at the top of the window. This will open up a dialog box where you can specify how much space you want Photoshop to take up on your screen and how large your photo should be when it is finished editing. Once you have made your choices, click on OK to close out of the Resize Image dialog box. Next, go back to Photoshop’s toolbar and click on the “Image” button located in between the “Type” and “Size” buttons. This will open up Photoshop’s Image Window where you can start editing your photo! ..
