The iPhone's built-in camera allows you to capture the moment no matter where you are. If you want to give your pictures a little personal touch or creative flair, though, you can download apps for your iPhone that allow you to draw directly on them. Some apps offer a more specialized customization, such as adding comic book-like speech bubbles or distorting faces with funhouse effects, while others let you draw and paint over your photos.

Tap the star-shaped button to add stickers. Tap the blob-shaped button on the far right to select a color and a width for drawing. Use your finger to draw over the photo. Tap the shirt-shaped button at the top of the screen to print this image on a product, like a mug or a T-shirt.
