Everybody loves Instagram and its effects, and one of the most used effect is the Classic Light leak effect, i frequently like to use them on my Pictures and many people do, sometimes when i look at a picture, i am totally unsure if it is good Photography or just Instagram...(Just Joking, i know good Photography is necessary if you want to apply filters later.)
When you are not having Instagram with you or just can't use it for any of the Gazillion reasons, and are left with only your good old Photoshop, then you might have wondered, how to do that in Photoshop ?

Answer is here, i have written a detailed and quick tutorial on how to do it, and will include a Photoshop Action too in case you want that effect in a Flash.

So here, Let's start with the tutorial :-

1. First open up the Picture you want to enhance with the light leak effect.

2. Then go to Layer > New Adjustment layer > Curves, and try to modify the Output and Input levels to the below screenshot, it may be different too, as may seem fit to you.
