Recently, I've been playing with adding textures to photos. There are an endless variety of looks that can be achieved.
Here is the normal photo of the cupcakes...
And here they are with a texture layer applied. It makes a great vintage style look. I used Photoshop Elements 8 to add the layers.
Multiple layers can be applied and opacity can be adjusted to vary it from lighter to darker.
Textures can be found easily by Googling it but a great site to get free textures and learn more about them is Kim Klassen Cafe. She has great information, tutorials, videos, tips and more. And, she's the newest Shutter Sister too. Give it a try - it's great fun and a cool way to vary your photos.
