[0.225 lb] V3 has improved approach to reading white balance. The adapter ring can be helpful, but also needs getting used to... but isn't necessary to use the ExpoDisc... User manual could be more inclusive; but targeted videos were made.

[3" / 77 mm] From the time of their introduction to the market, panchromatic emulsions have been know to retain some of the sensitivity to blue light than the human eye does. Modern emulsions are better, but still benefit visually with the use of a Wratten #8, a.k.a. K2 yellow filter. Being a throwback stubbornly devoted to film, my lenses always have a #8 aboard, whenever I’m making black and white images, unless other contrast control filters are needed for specific circumstances.

I can’t say I have done any technical comparisons between the actual bandwidth of filters manufacturers, but have used Tiffen filters for years, with no problems. My only minor gripe is they use aluminum instead of brass rims, which can lead to more frequent jamming, unless extra care is used when installing them. In a perfect world, they would use brass for their rims, and maintain their price point. And my car would start reliably at temperatures below freezing...

Users should always keep a filter wrench in their kit when using these. I also treat my filter’s threads with a VERY LIGHT film of synthetic lubricant like SuperLube or Syl-Glide.

Avoid lithium grease for all photographic equipment! It’s reactive with most of the alloys used in our precious gear, and degrades into a hard cheesy mess over time.

Anyway, Tiffen filters have never disappointed, and are a fine choice, compared to the pricier brands. Of course, ULF users probably could care less, but still—

[3" / 77 mm] Upon buying the DV3 and receiving it, I immediately tried it at my favorite place to photograph. I used it to obtain a good white balance and then on to photograph a few eagles. When I returned home, I downloaded all of the images and the good white balance. The results were excellent & totally calibrated with the ExpoDisc. This saved me some time in post just attempting to obtain a good white balance.

[0.225 lb] I purchased this when I traveled to shoot a friend's wedding and realized I forgot to bring the Expodisc I've had for years.
It's not that often that I find myself in a situation where using it is required, but when that does happen, it makes things a lot easier.

[0.225 lb] I recently upgraded my camera to a Canon R3 and wanted to incorporate a solid start to white balance before I start a photo session. This has proven to be a worthwhile investment and will be part of my kit from now on.

[0.225 lb] Its been perfect as an all-around filter for shooting black and white film.

[3" / 77 mm] I used in muy black and white photos, the results are great, highly recomended for the price!!!

[0.225 lb] High quality filter gives fantastic results. Highly recommend.

[0.225 lb] The NiSi Allure Soft White filter is great for creating a soft and diffused glowing effect, and it also reduce contrast. Great for creating a soft Cinematic Look!

[0.225 lb] I've decided to standardize on 77mm filters going forward. That way I need to buy only one of each color/type. I have no plans to buy or use any lens using filters larger than 77mm. I'll use step-up rings to adapt the filters to those lenses I use that use smaller diameter filters. this filter is a quality item and I've rated it at '5' for that reason.
