Adding images in Photoshop is easy if you follow a few simple guidelines. We explain how in our Adobe Photoshop courses.
We usually set up our blank page or banner first. Then open one or two images to bring into the blank page. If you require the image to fill your canvas, go to the top drop-down menus and choose Window > Arrange, and choose one of the Tile options. You’ll now see the images displayed side by side. Go to your Move tool, click on the first image, then click and drag it across into your blank canvas.
Chances are you’ll have to rescale it to fit the canvas, so go to Edit > Free Transform, or a good keyboard shortcut is Control + T (Mac: Command +T). This allows you to do three things: move, scale or rotate the image. Press Shift to keep the width and height proportionate, then click and drag one of the white anchor points. Take your finger off the mouse first, then your finger off Shift, and hit Enter to finish the operation. The image will be cropped when you save and close it.
In the example shown here, of various objects cut and pasted into the scene, you would have to use one of the nine selection tools to first select the pixels you want to copy across. Then select the Move tool (the shortcut is V on your keyboard), and click and drag your selection across into your canvas. Doing so creates a new layer each time – we cover layers in another blog post. Another method would be to copy across the image as a whole and mask out the parts you don’t want visible – again, we explore masks in another blog post.
