I have been doing galaxy overlay for years now and it never ceases to amaze me every time I experiment on photos on how they would look with a galaxy twist. This 'ible will show you the simplest way to make your images "more" interesting.
WHAT YOU NEED?
1) Photoshop - Any version will do, I used CS4.
2) Galaxy Photos - Stock images, wallpaper I downloaded from Google.
3) Subject Photo - Subject photo you want to work on.
Step 1: Open Image With Photoshop
Open your subject image with Photoshop. One good thing to remember when choosing the right image is the balance of lightness and darkness. Remember that the overlaying image would only work on the dark part of your picture. Once you have chosen a subject image, it is a good practice when working on an image to duplicate them.
