Hoya pl-cir filter how to use it

Taking pictures with Cir-PL filter

A polarization filter can give your recordings more contrast and radiance. There are a few small things to consider when using it.

In addition to ND and gray graduated filters, polarizing filters and circular polarizing filters are among the most important filters for landscape photographers. Polarizing filters enable an image look that is difficult or impossible to achieve with subsequent image processing.

In particular, circular pole filters like the HOYA Fusion ONE Cir-PL, for which the strength of the effect can be varied by rotating the front element, are particularly useful here. By turning the filter wheel, the desired effect can be adapted to the currently prevailing lighting conditions by increasing or decreasing the filter strength.

No matter how good you are in terms of image processing, the result will not be the same as if you used a polarizing filter to help you take photos from the outset. Because while colors and contrasts can certainly also be improved with software, mirroring and reflections on non-metallic surfaces such as water, glass, but also on leaves in nature, can hardly be removed afterwards.

Especially in landscape photography, when a bright blue sky with vividly protruding white clouds or a lush green in nature are required, polarizing filters belong in the photo bag, or better, in front of the lens.

Polarizing filters work by reducing the polarizing light that is reflected from the sky, water, and other surfaces. You will achieve the best results when you take photos at a 90-degree angle to the sun.

The use of the polarizing filter makes little sense if you have the sun directly behind you or if you are taking photos under a cloudy sky.

Remove reflections

Cir-PL filters are also used when it comes to avoiding reflections on non-metallic objects such as glass or water surfaces. These can hardly be removed even in the best image editing program. Unless you want to use this as a stylistic device. The use of a polarizing filter makes life as a photographer much easier.

Probably the most popular application of a CIR-PL filter is to accentuate clouds against the deepest blue sky possible and to intensify the rich colors of nature by removing the reflections on leaves, grass, etc. CIR-PL filters are therefore considered by many photographers to be denotes the most important filters of all.

Reflections on vehicle paints can also be reduced with a Cir-PL filter. Because the paint itself is non-metallic. However, there are a few restrictions here. Polarizing filters can only give anti-reflective properties to a narrow "angle range" of a car, especially if it is at an angle to the camera. The reason for this are rounded shapes compared to the sky, window panes or water surfaces.


How to use the polarizing filter correctly

Choose the right diameter

The polarizing filter is screwed onto the front of the lens, so the correct diameter is crucial. Leading filter manufacturers such as Hoya have the right filter for almost every lens. By the way, you can read the correct diameter for the filter on your lens.

The preview of the filter effect

To get a preview of the expected effect, simply look through the unscrewed filter towards the sky.

If you use a circular polarizing filter (CIR-PL) you can watch the intensity of the effect by turning the outer ring. Light incidence from the side

In bright sunlight and clear skies, you will achieve the best results with polarizing filters if you take photos from the side of the sun.

It is important to know that polarizing filters reduce the light by approx. 1-2 f-stops. You should therefore increase the ISO value accordingly if you are taking photos without a tripod.

The correct direction of exposure

When the sun is at a 90-degree angle to the camera when taking the picture, the effect of the polarizing filter is greatest.

5 ideas for using the CIR-PL filter

Contrasting clouds

Cir-PL filters increase the saturation and the sky is displayed in a more intense blue and clouds emerge vividly.

By removing reflections on leaves, the green of nature is also shown more richly.

Clear water surfaces

Reflections on the surface of the water are removed and allow a view to the bottom if the depth is appropriate.

For this, the surface of the water should be smooth and the sun should be around 40-70 degrees above the horizon

Less reflections

If you don't want to use reflections as a stylistic device, they can largely be removed from window glass or other surfaces with polarizing filters and - photographed at the right angle - ensure a clear view into the interior.

Less gloss on surfaces

Shine and reflections on surfaces can be greatly reduced. This is especially interesting when you are photographing cars. Also important here: take pictures at an angle of approximately 90 degrees to the sun or light source.

Dramatic black and white images

Cir-PL filters not only emphasize the colors. The subsequent conversion to black and white creates incredible contrasts. This is how a deep blue sky becomes almost black.
