Getting Started with Moment CineBloom Diffusion Filters (10% & 20%)

Everything you need to know about Moment's best-selling CineBloom Diffusion filters in both 10% and 20% strengths. How to mount, best use cases, tips, and more.

What's a CineBloom Diffusion Filter?

If you want that buttery, film-like glow without switching cameras, Moment’s CineBloom diffusion filters soften harsh digital sharpness, bloom highlights, and smooth transitions — so skin looks kinder, practicals look dreamy, and your footage feels more “cinema,” less “clinical.”

Modern sensors are crazy sharp. CineBloom adds a controlled micro-haze that:

  • Softens hard edges and transitions
  • Blooms bright sources (lamps, windows, streetlights)
  • Smooths skin without turning to mush
  • Keeps contrast and color intact thanks to premium Japanese glass

Below is a quick, friendly guide to picking a strength, finding the right size, and getting your filter mounted; plus real-world tips from set.

Cases Uses for CineBloom

CineBloom filters are made to live on your lenses, not in a drawer. Moment's rugged aluminum frame and premium Japanese glass can handle dust, dirt, bags, car consoles — pretty much the chaos of real shoots. I’ve tossed mine into rough weather, set them on rocks between takes, and they’ve come out unbothered. You should still pop them back into the included hard case when you’re moving locations or wrapping for the day, but you don’t have to baby them.

10% vs 20%

On a recent music video in Lyttelton, New Zealand, we lit the scene with a softbox key, an overhead lantern, a rear fresnel, and a flagged spotlight. That mix of sources made it easy to see how each strength behaves.

The 10% gave us a clean, natural image with just a hint of glow, which is great when the director asked for something more polished yet natural. It adds pleasing bloom and smoothing skin while keeping detail intact; it quickly became the default for most setups.

When we wanted a stylized, dreamy moment, the 20% delivered a strong vintage vibe, softening skin and letting highlights bloom in a big, cinematic way.

Pro Tips for Best Results

Think of CineBloom as a lighting enhancer. Place practicals — lamps, windows, neons — inside or near the frame to give the filter something to bloom, and favor backlight or edge light for that “wrap” around faces.

Midday, front-lit scenes will look flatter, so try shifting angles or adding shade for shape. If you’re shooting wide open, consider stopping down a fraction to keep faces crisp while highlights glow.

VND + CineBloom

If you plan to stack a CineBloom with a Variable ND Filter, put CineBloom closest to the lens for easier cleaning and fewer reflections.

Or, better yet, if you don't yet have a CineBloom filter, try out our latest combined CineBloom VND filter that gives you a 2-in-1 look without the need to stacking.

How to Find the Right Size

Ø = your friend

  1. Check your lens barrel for the Ø symbol followed by a number (e.g., Ø67).
  2. That number is your filter thread diameter in millimeters.
  3. Match your CineBloom to that number (e.g., Ø67 lens → 67mm filter).
If you're shooting multiple lenses with different threads, try step-up rings so one larger filter fits them all.

How To Mount the Filter

  1. Open the hard case, remove the filter by its rim (avoid touching glass).
  2. Line up the threads on the filter and lens.
  3. Pro trick: Start by gently turning counter-clockwise a couple of rotations until you feel a tiny “drop” as the threads seat—then turn clockwise to tighten.
  4. Snug, not gorilla-tight. Over-tightening can make removal tough.
