I have never tried using textures in my photos. I just learned how to use them lately and have been doing some experiments. I am enjoying this new found way to create a new look of my photos. I did not realize it's just easy. Either you use some already existing textures or you can even make your own textures.
I discovered that the technique is just easy. You just have to use the blend modes in the photo editing software, like Photoshop.
I have written a step by step article on using layers and blends in my hub in HubPages. The link is here if you are interested. How-to-Change-the-Mood-of-Your-Photos-Use-Layers-and-Blending-Options
I am just sharing a photo that I created by using this technique. Try it and have fun!
