How to Use a Moment CineBloom Diffusion Filter: See the 10% vs. 20%

Why Use a Diffusion Filter?

They take the edge off overly sharp digital footage, soften highlights, smooth out skin, and give everything that hazy, cinematic glow you usually only get from vintage lenses or old film stock. Bright lights bloom in a soft halo, skin tones look more natural, and that overly crisp, clinical look most modern cameras seem to really over do.

Diffusion filters are particularly useful in portraits, moody landscapes, street photography — really anything where you want a little extra atmosphere without over-editing later. I know forwards do a decent job of mimicking this look (or a smudge on your lens, lol), but they don't offer the dynamic range needed to get a truly good shot; one that's easy to edit or color correct.

Aside from the creative perks, they double as a layer of protection for your lens too. If you tip over a rock and your camera falls face-first, the filter cracks first and your lens is saved. Speaking from personal experience here...

The 10% vs. 20%

The percentage listed on each filter tells you how strong the diffusion is. 10% gives you a softer, more natural bloom, while 20% brings a stronger, more stylized glow. It’s an easy way to control the vibe of your image. Every strength is available in all our current filter sizes, so you can pick the look you want without worrying about compatibility.

The 10% is our most popular filter density because of its subtle yet complimentary bloom around light sources, which gives an angelic glaze in all the right places. Personally, this density is great for never having to take the filter off; it could easily live there and give your portfolio a more refined signature look.

The 20% is ideal for stylistic shoots, offering a more extreme haze than the other. Its ultra-diffused light sources and creamy skin tones will take your image to the next level. It's way easier to use a glass filter than Photoshop AI tools.

Stack It With Our VND Filters

The stacking capability with our Variable ND filters is a super convenient feature that extends beyond its evident diffusion qualities. You get the sick cinematic visual experience with our time-tested VND filters producing a buttery shutter speed and a nice bloomed effect. Mix the various ND stops and diffusion densities to your taste and let it rip.
