Katsushika Hokusai 葛飾 北斎,  From Bird and Flower Paintings, 1816

There are lots of fantastic free options for lens flares, light leaks, and film grain out there. I created a few of my own that I am making available here:

NATUMS 35MM FILM GRAINS - Four 1080p variants and a 4K

NATUMS LENS FLARES AND LIGHT LEAKS

NATUMS DIGITAL EFFECTS - These are digital effects shot on an LCD screen so you see defined RGB pixels. They can create interesting effects.

NATUMS VHS EFFECTS (ADDED Aug. 1, 2012)

There is no perfect grain or flare for every project though, so I consolidated a list of the best free ones I’ve found.

I have a SAMPLE REEL that was a project using various burns/flares & digital textures
