B+W 060 yellow-green (11)

This filler is ideal for scenes where it is important to differentiate the green tonal values. The application is especially suited to landscape photography in the spring and summer as it enhances the light green colour of the leaves. Due to its favourable effect on red tones, this filter is also suitable for portraits or group pictures taken in natural light.  Filter factor is approx. 2.

B+W 061 green (13)

A dark green filter that creates distinct differentiations of green tones in late spring and summer. It is also recommended for floral pictures that are used graphically, for tonal separations in still-life photography, and for the correction of red tones in portraits with high-speed film.  Filter factor is approx. 3.0.

B+W 090 light red (25)

This filter is ideal for enhancing contrast. In landscape and architectural photography, it enhances white areas, for example, letting clouds stand out clearly against a darkened sky and drastically reducing distant haze. It is also used for tonal separation in still-life photography.  Filter factor is approx. 5.

B+W 091 red (29)

The use of this filter gives a surrealistic effect in landscape and architectural photography by producing a "storm-like" cloud effect, "moonlight" effect, and "wood" effect. It is indispensable for tonal separation in still-life photography and for the reproduction of documents which have become illegible.  Filter factor is approx. 8.

B+W 092 (89B)

This dark red filter is for black and white infrared films and filters out light below approximately 650 nm. It allows pictures of a pure red image while making good use of the relatively low sensitivity of infrared films. Filter factor is approx. 20 - 40.

B+W 099                                                                       (for black and white IR or colour IR photography)

This orange coloured filter blocks the blue and blue-green portion of the visible spectrum up to approximately 520 nm. It reduces the excessive sensitivity of colour infrared films for this spectral range, helps avoid a blue tint and differentiates colours more evenly. Filter factor depends upon the film sensitivity.

B+W Circular Polarizer   Nikon Circular Polarizing Filter          (for black and white or colour photography)

This filter is specially designed to be used with auto-exposure and auto-focus SLR and video cameras. It does not influence the metering systems of these cameras.  B+W:  Filter factor is 2.3 to 2.8.  Nikon:  Filter factor 2 to 4.

Hoya R72 Infrared – Dark Red

The R72 filter looks almost opaque. The filter only passes light from the very high red edge of the visible spectrum and infrared light. Due to the nature of infrared light, filter factor and exposure compensation vary widely from visible light and depends largely on lighting conditions.

1. •Works well with digital cameras, especially with no IR blocking filter in front of the sensor. (Please check your camera's owners manual.
   

1. •Only passes light at 720nm (high-red) and above. Gives more predictable results than a filter that only pass Infrared light above 850 or 900nm.
   

1. •Can be paired with coloured black and white contrast filters such as the R25 (red), K2 (yellow), O (orange) or other colour filters to change the colour rendition or contrast effects.
