PGY 2401C PHOTOGRAPHY I

Black and White Contrast Control filters

You can use filters to lighten or darken various colors in a scene selectively. Using a filter similar in color to colors you wish to render lighter , or using a filter complementary in color to subject colors you wish to darken.

The number in brackets () shows the corresponding Kodak Wratten filters.
The number in brackets [] shows the corresponding B+W filters.

UV- Colorless (0) [UV 010]

The colorless UV filter prevents the lack of sharpness caused by UV radiation and reduces distant haze. Since there is no change in color or exposure , the filter is well suited for protection of each lens. Filter Factor: 1x

Pale Pink. (1A) [KR 1.5]

Due to its light pink color, reduses the blue cast of daylight, resulting a warmer picture tone. At the same time absorb ultraviolet radiation and reduces haze in the scene. It is also known as a skylight filter. Filter Factor: 1,1x

Yellows
Pale Yellow (2A)

Absorbs ultraviolet radiation below 405 nm. Used with B&W film to reduce haze. Filter Factor: Filter Factor:1x

Light Yellow (2E) [021]

Reduce the blue components in shadow, which enhances detail. Clouds are accentuated. In landscapes, produce a better separation of green tones, and at long distances once reduce haze. For portraits, this filter reduces freckles and red spots on skin and darkens blue eyes. Filter Factor: 1.5

Medium Yellow (8) [022]

Widely used for correct rendition of sky, cloud, and foliage in Black and White Photography . Filter Factor: 2x

Dark Yellow [023]

In landscape photography, this filter renders blue skies darker, clouds lighter and diminishes distant haze. Increases tonal separation in fine details. Useful for copying documents on yellowed paper. Filter Factor: 3x

Yellowish Green (11) [060]

This filter is ideal for scenes where it is important to differentiate the green tonal values. The application is especially suited to landscape photography in the springtime because it enhances the light green color of the lives, and reduces distant haze. Ideal for portraits in nature. Filter Factor: 2x

Oranges
Yellow-Orange (16) [040]

This bright orange filter darkens blue and violet as well as green and yellow-green. It is indispensable for all landscape and architectural photography which require vivid and clear contour. The sky id distinctly toned with the clouds clearly contrasted against it. Also is popular for nude photography under natural light. Filter Factor: 4x

Orange(21)
Contrast filter used for blue and blue-green absorption.

Deep Orange(22) [041]

Contrast filter with greater green absorption than Orange . Dramatic 3-dimentional effects in landscape photography. Creates a strong darkening of the sky, dramatic storm-like cloud reproduction, and strongly enhanced shadows due to its enhanced contrast. It also achieves good tonal differentiations in still-life photography by brightening yellow, orange, and red. Not suited for portrait photography. Filter Factor: 4x

Reds
Light Red(23A)

Contrast filter with greater green absorption than Orange. Brighten red, orange, yellow-orange and yellow. They suppress purple, blue, green.

Red(25) [090]

Contrast effect in commercial and outdoor Black and White photography. In landscape photography increases contrast in cloud formation dramatically. Haze is reduced and white surfaces appear brilliant . In portraiture skin appears porcelain white. It is also used for tonal separation in still-life photography. Filter Factor: 5x

Deep Red(29) [091]

For better separation of tonal values from red to blue in object photography. Can produce moonlight effects in daylight due to the extreme darkening of sky. Gives a surrealistic effect in landscape and architectural photography, producing a storm-like 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: 8x

Blues
Light Blue(38) [080]

Contrast filter with some ultraviolet and some red absorption. Useful for correcting tendency of reds to reproduce too lightly in tungsten illumination. It is also used to darken skin tones for portrait or nude photography under natural light. When photographing objects , there is better separation between red and blue tones. Filter Factor: 1.5x

Blue [081]

Stronger effect of the Light Blue. Enhances the tonal rendition of the sky by emphasizing mist in valley and transmitting light rays over water, fog, and haze. Also, this filter is used for the tonal separation in still-life photography and the correction of the light spectrum from artificial light source. Filter Factor: 2x

Deep Blue(48A)
Provides some green absorption and strong absorption in the yellow, red, and ultraviolet.

Greens
Light Green

Absorbs some blue and red. Lightens up yellow-green tones. It is the standard filter for landscape photography. Filter Factor: 2x

Green [061]

Stronger effect of the Light Green filter. This filter 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 correction of red tones in portraits with high-speed film. Filter Factor: 3x

PART 2 - Light balancing filters

These filters used to increase the color temperature slightly for a warmer (redder) or decrease the color temperature slightly for a cooler (bluer) tone. They are intended for use over the camera lens. If the color temperature is already known, using the Mired Nomograph, you can obtain the required Light Balancing filters.

The number in brackets () shows the corresponding Kodak Wratten filters.
The number in brackets [] shows the corresponding B+W filters.

(81A) [81A]


This filter balances color temperature from artificial light sources to the color tungsten film standard of 3200 degrees and balances the difference up to 3400 degrees. Due to this characteristic, a noticeable warmer color reproduction is produced. 3400K -> 3200K Filter Factor: 1,2x

(81B) [81B]

This filter makes possible a stronger color temperature balance from artificial light sources to 3500 degrees which also results in a slightly warmer color reproduction. 3500K -> 3200K Filter Factor: 1,2x

(81C) [KR3]


This filter recommended for daylight photography, especially in spring and summer with cloudless skies and clear air. It helps eliminate the strong blue tone and haziness, which is produced by this level of ultraviolet radiation. It will reduce the unwanted blue tone in shadow areas with an overcast sky. 3600K -> 3200K Filter Factor: 1,2x

(81EF) [KR6]


This filter recommended for daylight photography, with high percentage of blue (as midday in the mountains during the summer). It block ultraviolet radiation and reduce blue tones in the shade. Also penetrates light fog. 3900K -> 3200K Filter Factor: 1,4x

(82A) [KB1.5]

This light blue filter absorbs the excess yellow-red light from daylight in the morning and evening hours. 3000K -> 3200K Filter Factor: 1,1x

(82C) [KB 3]

This filter corrects red tones when using 500Watt flood lights with tungten film. 2800K -> 3200K Filter Factor: 1,2x
