It’s really really really surprisingly easy. Like, it only generally takes three steps. As usual, you will need Photoshop.
I hope you find this little tutorial helpful (the way I find colon cleanse products helpful hrhrhrhr)!

Step Three: Choose the color you want for your “light leak” (lol). I particularly like hot pink/red or purple, but it’s up to you. Set it as your foreground color.
Click the create new fill or adjustment layer button on your layers palette and choose ‘Gradient’.
Adjust the angle to your liking. I like the color on the upper right corner but again: it’s up to you.
Set the gradient layer’s blend mode to ‘lighten’.
Adjust the layer opacity according to your preference. You can also use more than one gradient layer/one color:
