Step 1: Prep your photo. I cropped mine to 500X250, but you can do any size you like. Sharpening may be necessary, but I didn't do it. As always, it depends on the photo you choose.
Step 2: Duplicate your base and set it to screen at 100% opacity. If it's too bright, lower the opacity to suit your photo. If it is too dark, duplicate the screen layer until it is bright enough. Mine looked like this:
Step 3: Add a new layer and fill with a dark blue (I used #03031b) and set it to exclusion with an opacity of 100%. Duplicate this layer. Your image should look like this.
Step 4: Now flatten your image, because here comes the tricky part.
Select and copy the image by pressing ctrl+a and then ctrl+c. Then press ctrl+z TWICE and then ctrl+v. A new layer should be on top of the others. Set this new layer to soft light at 100% opacity. You might need to duplicate this layer a few times. I duplicated mine three times. But as always, it is image dependent - so play around!
My image now looked like this.
Step 5: Texture time!
I pasted this texture by sanami over the top and set it to Multiply at 75% opacity. Remember, play around!
My image now looked like this:
Then I pasted this texture by...I'm not too sure (if it's yours, let me know!), over the top and set it to Screen at 40% opacity. Remember though, play around!
After this, you should have your finished product!
Now, you can add brushes, text - WHATEVER! This was just a guide for the base. :D
Also, my layers looked like this:
Made in PS CS2, but it seems pretty transferrable...
