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

We had no idea how well-received our beloved CineBloom diffusion filter would be during our initial launch in September 2020. Our gear team perfected every inch of the filters’ surface to supply creatives — both photographers and filmmakers alike — with a product that could easily achieve dreamy-looking imagery. They are the perfect testament to film-like photos without breaking the bank with film stock while producing a beautiful hazy glow around lit subjects. They aim to create a unique style of visual appeal that you wouldn’t otherwise be able to manipulate in Photoshop easily.

We love these little guys and are so happy you do too.

After a couple of years with these babies in the hands of thousands of creators, we wanted to apply further our knowledge on how to use a diffusion filter properly and further discuss key differences between our various available densities: the 5%, the 10%, and the 20%.

37mm CineBloom Diffusion Filters Review

We’ve shot with a lot of filters, and nothing caught our attention quite like diffusion filters. But they weren’t meeting all of our needs... so we decided to make our own.

Available in densities of 10% and 20%, Moment CineBloom Diffusion Filters are the secret sauce to capturing dreamy, film-like footage. Escape the clinical, ultrasharp look of digital with this specialty glass. It not only catches and blooms light, but has a smoothing effect on skin tones, making wrinkles less noticeable. The ring of the filter is precision machined from aerospace grade metal, delivering the durability we expect for all of our shoots. It’s also specially designed to be thin enough to stack underneath another filter without compromising field of view. This means you can use an ND or VND on top of it for shooting cinematic frame rates and capturing motion blur. The glass itself is made by fusing a micro layer of black particulates between two layers of top grade Japanese filter glass, allowing us to maintain full image quality. We are able to precisely control the density of these particulates to offer 2 different strengths of diffusion filters. Take your footage to timeless, cinematic heights with CineBloom from Moment.

The Purpose of a Diffusion Filter

A diffusion filter is made to serve several purposes, for exmaple…

  • Blooming any light source
  • Lessening your camera's clinical sharpness
  • Softening skin tones
  • Cutaway wrinkles, clarities, or visual imparities
  • Achieving a more vintage illusion
  • Creatively adds a dreamy or hazy vibe to your scene

Lens filters are a wonderful protection layer against scrapes, hits, or drops — but, more importantly, they serve a variety of use cases. Diffusion filters are endless in possibilities and versatility, making them the more popular choice for creatives wanting to purchase their first camera filter. A fantastic option for both photographers and filmmakers, creators find the CineBloom to serve many creative needs.

The 5% vs. 10% vs. 20%

These numerical percentages next to the filter’s name are confusing to some, so let’s discuss what these mean and how to choose which one is right for you.

Each percentage refers to the density of the filter's diffusion, with 5% being the least noticeable, 10% being a perfect middle, and 20% offering a more stylistic glow. These varying solidity offer creatives more control over how much diffusion effect will occur in your image. Our three percentage options are available in all the current filter sizes on the site, giving you the ultimate freedom to choose.

The 5%: This is everyone's favorite filter, never to leave the lens. Subtle enough for every scene or image but soft enough to remove that harsh digital clarity.

The 10% is our more popular filter density because of its perfect middle ground. While more of a noticeability than the 5%, our 10% CineBloom filters offer an angelic glaze in all the right places.

The 20%: More ideal for stylistic shoots, offering a more extreme haze than the other two. Take your image to the next level with its ultra-diffused light sources and creamy skin tones.
