Ever wondered about the flare hitting your eyes from reflective surfaces (vehicle mirrors)? Let's create one. Open Adobe Illustrator with an image and embed it. Take the flare tool from tool palette. Draw the first shape and then second shape. To change settings, go to flare options. You can change the brightness, opacity and diameter of the flare which will add life to the image(open sky). This will help bring out some cool effects as well as realism to the image.
