There are many ways to change the appearance of inserted pictures within PowerPoint — you can use the various Adjust Picture options, and can also add distinctive borders to your pictures. And yes, you can directly apply preset Picture Styles. These Picture Styles are based on PowerPoint’s Picture Effects capabilities and add some effects with a click. Most of the time, this means that a single Picture Style adds a reflection, a glow, and a border to your picture. However, you can also apply any of these effects individually to your pictures. In all, PowerPoint provides 6 effects: shadow, reflection, glow, soft edges, bevel, and 3-D rotation.
