Whether they are solid (ND) or graduated (GND), neutral density filters reduce the amount of light that reaches the sensor, on the whole image or partially depending on the filter. They emphasize the flow of movement, reduce the depth of field, and avoid overexposure. They are also useful in video to maintain constant shutter speed and optimize bokeh capabilities with bright lenses.

Some colored filters are still widely used by photographers working in Black & White. In both film and digital, they have a strong effect on tone, saturation and contrast, depending on how you capture black & white images. This category also includes infrared filter and its unique possibilities.

Conversion filters help rectify strong color temperature variations. Lighter density versions of these blue or orange filters apply subtile color temperature corrections that reduce or eliminate dominant tones.

When the sky is not as blue as you wish, when the sunset is not vibrant enough or if you would like to add a personal color touch, the graduated colors are the ideal choice. They darken a part of the image (generally the top part) by adding a color: blue, tobacco, emerald, sunset, etc.

Color correction filters compensate dominant monochromatic colors. Working on the principle of subtractive syntheses of colors, these filters – each available in 6 different intensities that can be combined as necessary – allow for correction of any chromatic discrepancy.

With these filters you enter right into a romantic atmosphere. They add a soft, unique touch to portraits; hair flows like silk, skin is warm and expressions languid. As for still lives, they come close to the appearance of a painting, attaining an incomparable atmosphere that is delicate and fresh. These filters give superb outdoor results, in cloudy weather, and indoors when light is coming sideways from a window.

Several optical effect filters are available to stimulate your creativity.
