[0.1 lb] 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.

[0.1 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 !

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

[0.1 lb] 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.

[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?

[Glass] 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.

[Aluminum] I was worried that a 1 strength would be really glow-y the way a promist would, but you only really see an obvious glow in very strong back-lit or high contrast conditions. Otherwise it's a very a very gentle touch on highlights and overall contrast.

Also the idea that a sparkly filter inspires confidence in a model is the silliest selling point I've ever heard, and my models laughed at the idea of it ... which got me some genuine smiles, so I guess there's that.

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

[0.1 lb] Adds a subtle glow and sheen to the image, really helps breath some organic life into even the most sterile digital cameras.

[0.1 lb] 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!
