ND64 + CPL Polarizing Filter Plus+

Let the quality of your lens guide your choice. Or simply go for the best – our professional Plus+ range.

Urth has two different ranges of filters: Urth (our premium range) and Urth Plus+ (our professional range). Let the quality of your lens guide your decision. If you’ve invested in a professional-quality lens, we recommend you match its quality with our Plus+ range. Our Urth range is the perfect option for all other standards of lens.

Use the 90-degree rule, then back it off a bit.

To achieve the strongest polarization possible, the reflected light source needs to be at 90-degrees to your CPL. To check this, make an L-shape using your thumb and index finger. Point your thumb at the lens and wherever your index finger is pointed, that is the angle that will achieve maximum polarisation. Sometimes at full polarization, the effect can look unrealistic so we suggest you back it off a bit for a slightly softer polarization.

Yes, we recommend our Plus+ range for telephoto lenses.

Make sure you have the right size filter and you’re all set. All our filters are designed with a super slim rim to minimise any vignetting that can occur with wide-angle lenses. Because of the amount of glass in a telephoto lens, Ous Plus+ range will provide the best image quality.

A circular polarizer blocks reflected light from any angle while a linear polarizer only blocks reflected light from one direction.

A CPL offers more versatility and works better with digital cameras. Both linear and circular polarizers look the same, and they both do the same thing – reduce reflections on non-metallic surfaces such as water, glass and wet surfaces, and they increase colour saturation too. A CPL filter is essentially a linear polariser with an extra glass element that allows you to adjust your lens filter to block polarised light from different directions.

Yes but only a little – 1.33 f-stops.

A CPL filter will reduce the amount of light reaching your sensor by about 2 f-stops.

The best ND filter for your photography will depend on the effects you want to achieve.

The first choice you need to make it whether to go for a Fixed ND Filter or a Variable ND Filter. A variable ND filter offers more options, which is great if you’re shooting in changing light conditions, or just starting out with ND filters. A fixed ND provides a specific light reduction and works better with telephoto and wide-angle lenses. The next choice you need to make is the level of light reduction you want. The higher the ND number, the more light it blocks from reaching your camera sensor.

It depends on how, where and what you’ll be shooting.

Fixed ND filters block a fixed f-stop of light from entering your camera. Variable ND filters provide more flexibility and have a range of f-stops you can block by rotating the outer element. If you’re starting out with ND filters, we recommend a Variable ND so you have more flexibility while you’re learning how to shoot with an ND. If the light is likely to change often, a Variable ND saves you changing between fixed NDs each time.

Yes, if you want more than a 2 f-stop reduction of light.

While CPL filters polarize light to remove reflections and increase colour saturation, ND filters reduce the amount of light that makes it through to your camera’s sensor, which opens up opportunities to experiment with depth of field and motion blur effects even in bright light.

Our whole range of Fixed ND Filters work with wide-angle and telephoto lenses.

Our ND filters have ultra-slim rims to avoid any vignetting issues. Our Fixed ND Filters are all in our professional Plus+ range and use the world’s best glass, making them perfect for wide-angle and telephoto lenses.

The higher the number, the more light it blocks from entering your camera.

The 4 of our ND4 Filter Plus+ refers to the amount of light blocked. An ND2 reduces light transmittance to a quarter. An ND8 reduces it to an eighth, an ND1000 reduces it to 1/1000th.
