I would name this effect a sort of lens flare, but the lens flare tutorials I have seen on YouTube are not what I am looking for... Such as this tutorial
Anyway, this is the effect I am trying to replicate, as displayed in the Galantis - No Money Music Video
at the following times: 0:17-0:21, 0:27-0:31, 0:35-0:40 and many other places through out the video...Thank you for any responses I may get :)
Kind Regards
Joshua Lochner
