This 6.6 x 6.6" Tiffen ND Filter 6.6" 1.3-Stopis a solid neutral density filter providing a 1.3-stop exposure reduction. This 0.4 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By increasing your aperture or slowing your exposure time, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 6.6 x 6.6" / 167.6 x 167.6mm.

Q: 1. I want take water falls is this ND 0.9 (3 stop) capable ? for water fall? Or I need more darker ND filter what do you suggest?

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: 4. Would a 25-30 second exposure of a waterfall be possible on a partly sunny day at f/22?

A: You almost certainly need a denser filter, or double up on some NDs, unless you have an extremely low ISO. I doubt an ISO of 50 would be enough.

Q: 8. Other than having a vignette problem can I stack three of these 3-stop ND filters to achieve 9 stops down? The Big Stopper system is $200, I don't want to pay that, which gives 10 stop reduction. Or do you carry a ND 10 stop filter for $50 or so? Thanks

A: That is correct. While it would certainly create some vignetting, stacking 3 of the 0.9 filters will give you 9 stops of light reduction. If you wanted to use just one filter, you might consider a variable ND:http://bhpho.to/1cCfMcVThis will allow you to adjust the ND effect, while maintaining a relatively slim profile.

Q: 9. Any discoloration with the filter?

A: It depends on your camera. If you can white balance with the filter applied to the lens then you should be fine. I've had no issues and in general I don't worry about IR pollution.

Q: 10. Will this work on the Panasonic 20mm 1.7 lens? (lens retracts, so I'm not sure it will)
