Tonal Contrast (Color Efex Pro)

A filter in Color Efex Pro, part of the Nik Collection, to adjust the contrast with specific brightness ranges. For example, if the shadow areas of a photo are looking rather flat, you can boost them with the Shadows slider and leave the rest of the picture unaffected.

Old Photo (Color Efex Pro)

A filter in Color Efex Pro which offers a varity of vintage photo effects, from sepia-tinted black and white to faded colour. In some ways it’s been superseded by newer and more elaborate ‘analog’ film effects, but it still produces a range of attractive vintage photo effects.

Midnight filter

A filter in Color Efex Pro that takes a regular daytime shot and simulates the look of moonlight using a combination of darkening, colour shifts, desaturation and glow effects.

Glamour Glow

A filter in Color Efex Pro, part of the Nik Collection, which applies a soft focus ‘glow’ to an image with additional controls for colour saturation and ‘warmth’. This can be used to give portraits a soft, romantic look, but it’s also very effective for landscapes, still lifes and other kinds of photography where you want to create dreamy, evocative mood.

Duplex

A filter in Color Efex Pro, part of the Nik Collection, which combines a soft-focus ‘glow’ effect with a colour tone. It can prove useful for some effects, but it’s not a filter you’d use every day.

Detail Extractor

A tool in some Nik plug-ins which simultaneously brightens shadow detail, brings out detail in highlights and increases local contrast to produce a more intense and dramatic image.

Contrast Color Range

A filter in Color Efex Pro which intensifies the difference in intensity and contrast between colours. It’s effective in landscape photography, for example, for intensifying blue skies without increasing the saturation of the image as a whole.

Bi-Color filter

A filter in Color Efex Pro which applies one colour to the top half of the picture and another to the bottom half. You can adjust the vertical position (where the colour changes) and choose colour sets from a menu. There is another filter which lets you choose the colours yourself.
