Photoshop is a powerful image editor that can be used to create graphics, photos, and videos. It can also be used to change the size of objects and create illustrations. To change the size of an object in Photoshop, you first need to select it and then click on the Edit button. Then, you need to select the Size tool and then click on the small arrow at the bottom of the window. Next, you need to choose a size for your object. You can choose between pixels or inches. Once you have chosen a size, you need to click on OK and then press OK again to close the Edit window.
