[46 mm] Tiffen Filters are always the best when it comes to build quality, reliability and options they provide. I am super happy with my 2 Set of Glimmerglass!!:) They make the image naturally gloomy without washing out the entire scene.

Also B&H did a perfect job on shipping and customer contact! I live in Germany and my package arrived only 4 days after my order was placed. Thanks, you guts are the best!

[Glass] Great diffusion filter that adds soft contrast to take off the digital edge while retaining sharpness. Would highly recommend over other diffusion filters.

[Aluminum] Any time I decide on diffusion filters, the biggest considerations for me are the strength of halation and the amount of contrast I'm looking for. I usually default to Hollywood Black Magic as my standard diffusion filter. When I want something stronger and a big more vintage feeling I'll reach for Black Pro Mist. When I want something much more subtle, I'll go for Glimmerglass because the halation is under much better control than the other two. I usually aim for a 1 strength when I want to see the effect. Even then, it doesn't feel too strong.

[Glass] Works well so far, and is less obscene than even 1/4 black pro mist can be. And price is fair. Now why do these filters cost 500% more in rectangular shape?

[0.095 lb] Lots of reviews suggest the 1/8 for a more 'filmic look but I found that I needed the 1/4 strength to get that effect.

Note that focal length and the quality of the light itself will impact the outcome.

A note regarding the GG1: This provides a very noticeable effect in most cases. Maybe a tad too much for everyday use.

Tiffen needs a magical filter that works on the jpeg but leaves the raw alone !

[Aluminum] These are great little filters to add to your kit.

[0.095 lb] The Glimmerglass 1/2 is nice. The sharp edges are reduced but I still have detail. And being able to quickly pop off the filter for certain shots is awesome!

[46 mm] So I have used the GlimmerGlass series a lot as a large matte-box filter on the cinema cameras. But sometimes I go and shoot inserts on a lighter setup with my FX6 and a Zoom lens. For that purpose this filter is absolutely perfect. If the 1/2, 3/4 and 1/4 become available as 82mm filters I will purchase them.

[46 mm] I was looking for a filter that would bloom the highlights and practical light sources without decreasing the overall contrast of the image, and I think this was just the filter I wanted. Compared to Black Pro Mist and especially Cinebloom, the shadow levels and sharpness are maintained with this filter. The diffusion is just enough for me. To me, it seems it blooms the highlights and light sources just enough to look like my image was shot on film, but without being too dramatic or noticeable. I think if I were going for a more dreamy look, I'd go with a higher Glimmerglass strength or use something like Cinebloom.

[Aluminum] I love Tiffen's Glimmerglass 1. A very beautiful filter! Thoroughly pleased with my purchase.
