Adobe Software Tutorial

 In this tutorial provided by Photoble I learned how to add a retro color effect to an image. Here is the Before image I used:

 

Here is my After image:

 

To achieve this look:

1. Open the image you wish to edit and duplicate the Background layer. You will now have a layer called Background and a layer called Background copy. 
2. Make sure you still have the copied layer selected and using the rectangle marquee tool, drag the tool across the left half of the image. 
3. Press "ctrl+backspace" to delete the image, and fill that space with a red color.
4. Now Choose Select>Inverse to select the other half of the image.
5. Repeat step 3, except fill the empty selection with a green color.
6. Choose Image>Adjustments>Match Color
7. Change the source to the original Background layer you started with, and choose the Background copy as the Layer option.
8. Now you can adjust the settings of Luminance, Color Intensity and Fade to achieve the look you want. (I mainly adjusted the Fade option.)
9. Now you're done! Save your work and have fun doing these effects to other images you'd like.
