Another very commonly used menu in PhotoShop is the Image menu.In this menu you can find things that will help you resize an image or document, change your canvas size or make quick adjustments such as Crop and Reveal All.
You will also find adjustments for light and shadow levels, colors and brightness and contrast here.
PhotoShop offers a wide range of touch up features which take some time to learn and practice, many of which you will find right here in the Image menu.
