A 138mm Light Yellow #6 Filter from Tiffen is used for a slight increase in contrast with black and white films. Although not as strong as a traditional Yellow #8, it can still be used to make a difference in your photography. You'll find it boosts your contrast just enough to make the difference between a black and white print flat appears "flat" and one that displays the proper correction.

Tiffen's ColorCore glass is produced through a process that entails permanently laminating the filter material in between two pieces of optical glass that are ground flat to tolerances of a ten-thousandth of an inch, then mounting them in precision aluminum rings.

For Black & White Film    Not Quite As Strong As a Yellow #8    Black Aluminum Filter Ring    ColorCore Glass    Made in the USA    10-Year Warranty

Especially useful for added contrast between blue sky with clouds and foreground

Tiffen's ColorCore glass is sealed between two optical glass sheets. In this way, Tiffen can better control the various densities of their filters and thereby create more exact degrees of filtration. This process makes for greater accuracy of color as opposed to glass that is simply dyed and become subject to deviation during the dye process

Tiffen, a leader in the filter industry, proudly makes its filters in the USA and backs up its products with a solid 10-year warranty

Related Questions and Answers

Q: 1. Does it have a multi coating?

A: No, this filter is not multi coated.

Q: 2. Tiffen ND 0.9 filter dark enough for taking water fall ?

A: The best ND filter for photographing Waterfalls will vary based on the shooting conditions and the effect you are looking to achieve. By experimenting you will discover what works best for you. A 3-Stop ND filter is a good place to start. I would suggest getting a Circular Polarizer as well. A Circular Polarizer will reduce reflections off the water, and block some light as well. Here is a link where you can find Circular Polarizers on our site. https://bhpho.to/3xMEALl

Q: 3. Why is the filter so inexpensive? Is it just the small size?

A: Price is based upon the size of the filter. 52mm is one of the smaller sizes and is thus priced less than filters for larger thread sizes.

Q: 4. Hi, I own a Canon 60D with the Canon EOS 18-135mm kit lens. I am wondering if this Tiffen ND filter fits my lens or not. If not, can you provide me a link of the right filter I am looking for? I need a 3x and a 6x (maybe even a 9x).Thanks-Gianluca

A: The Canon 18-135mm lens uses 67mm sized filters. This one in question is too large as it is a 77mm size. Below is a link to all of the 67mm sized ND filters we offer on our website. On the left hand side are search result filters you may select to result only ones which suit your criteria, which they do have a section to narrow down based on density.http://bhpho.to/1pBCrIB

Q: 5. does this fit the p series cokin holder which is 52 mm? Is there a higher stop nd filter up to 10 stops {like the lee big stop nd filter) in cokin, lee or tiffen that will fit my p series filter holder from cokin?

A: The Tiffen Cokin P Neutral Density (ND) 0.9 Glass Filter will fit in the Cokin P filter holder. All of the Cokin P filter holders are the same size, and accommodate any filter designed for the Cokin P system. We carry several 10-stop ND filters for the Cokin P filter holder.

Q: 8. What's the exact weight of this filter in grams? Not the package weight, but the weight of just the filter.

A: The Tiffen 37mm ND 0.9 Filter, weighs in at 40 grams.

Q: 9. Can this filter be combined with the Tiffin 77MM variable ND filter to become a super stopper like lens?

A: I suppose it's possible if you put this on the lens first and the variND after but I can't imagine why you would want to. The coatings on this filter aren't very good and there'd be some loss in sharpness, not to mention weird color shifts.

Q: 10. Is this filter multi-coated?

A: The answer is a qualified - NO. Tiffen filters are not solid glass likemost other filters. They are created by a special lamination process.The dyes are mixed with thinners and solvents and they applied to aglass substrate. The laminate forms an ultra thin coating that isless than 1 mil thick. A second clear glass plate is placed on top ofthe coated glass forming a sandwich. The laminate filter is thensubjected to high heat and pressure to fuse it together. Since thecoating is between the two layers of glass it is protected indfinitelyfrom any wear. The outer surfaces of the filter are not coated to myknowledge. You can scratch tho outer glass but not the coating inbetween.
