For any of you that already have it here's a simple tutorial to vintage-ize a plain photo. This will also work with PhotoShop but you will have to do some translating because I don't know PhotoShop lingo.
1. Choose your picture and open it in GIMP.
#2: Under the "Colors" tab, choose "Hue-Saturation". I took the saturation down to -39 to make the photo look faded.
#3: Open a new layer and copy and paste the texture pic (or if it's your own picture, open as a new layer.)
#4: Stretch or shrink your image to cover the entire original picture.
#5: Choose the "Mode" of your layer to play with the texture effects.
You can find the Mode at the top of your right hand dock window. It's a pull down menu.
Try some of these effects:
If the effect is too dramtic, tone it down by lowering the opacity.
So easy, and there is no need to buy expensive programs.
