Leaking light into your images might sound like something bad, or a technical mistake, but it can actually really give your images style and impact.

When used properly, light leaks add a new dimension to photographs. Done wrong, however, and you could end up with your main subject obscured by a big blob of light! For this reason, many now chose to insert lighting effect artificially in post-production rather than chancing it in-camera.

Here, we look at five actions from Envato Market to help you add light leaks to your images in Adobe Photoshop, and tutorials to help you make your own.

Hot to Use Light Leak Actions

Let's take a look at Lomo Leaks Photoshop Action, to see how it runs and what exactly it does to your images.

Once you've installed your action, hit play and a box will appear asking you to make a selection. Go to the Light Leaks folder that came with the action download and choose which light leak you’d like to try. This is Light Leak 1:

After running the action, you'll see it’s produced a set of layers.

There’s a Colour Fill layer which adds a matte cast to your image. The Black and White layer puts a little more contrast and punchiness back into your shadows and the darker areas of your image. Layer 1 is a duplicate of the background image, with the Blending Mode set to Screen, which lightens it. You can mask out some of these changes if they don’t look right with your image.

Here's another example of how light leaks can brighten up a shot. This is the original image:
