Light Leak Effect in Pixelmator
Open photo you want to make light leak effect. I’m using girl picture.
Add a new layer, and in Gradient Toll choose Linear Type and fill this layer with soft yellow, mild pink and soft purple, like in picture below.
After that change Blending to Overlay, and Opacity to 30%. Now our making picture is more brighter.
Add a new empty layer and take Rectangular Marquee Tool, then make two rectangular – one bigger and another smaller. The colors you can choose, I’m making with yellow and orange.
Go to Filter > Blur > Gaussian and use 20.0px for the Radius.
Now just change Blending to Screen and Opacity to 60%. After that add a new layer and make one more thin yellow rectangular on the orange rectangular.
Go to Filter > Blur > Gaussian Blur and use 8.0px for the Radius.
Now just change Blending to Overlay and Opacity to 40%.
