The Type Tool
When you click on your canvas with the Type Tool activated, a box will appear that will allow you to type in any message you want. Not only that, but you can customize the text in a wide variety of ways– from changing the font (and finding new fonts using the integrated Adobe Fonts), to changing size and weight, to more detailed adjustments within the Character dialog like kerning, leading, and tracking.
Illustrator is the go-to for graphic designers when working with text, but Photoshop still has a lot of options for helping text work within a frame. The Move Tool has alignment options which can help you make sure that any new lines of text are in line with one another, or evenly distributed across the canvas.
Photoshop also makes it easier to have text interact with elements in an image. Want to have some of the text look like it’s behind a person in a photo? Try using Type along with Layer Masks to create a more dynamic image!
