How to achieve this:
First, we'll be starting with this image.
Now, duplicate, add, do whatever to make it more interesting :)
Then, I made a new layer on top of the image, used this gradient, and set the layer mode to screen.
I am going to leave it like this, but you can add more gradient, and play with the opacity until you find a better color :)
To spice it up, I put this image on top of it :)
You might want to duplicate it once :/
Seeing as I never save .psds, I just flattened it, added a few text for decoration, et voila!
Um.. I think it looks better without the text xD;;
Gradient ;) Credit
