Alien Skin has announced Exposure 4, a new version of its photography effects plug-in for Photoshop and Photoshop Lightroom on Mac and Windows. The company claims Exposure provides accurate film simulation and a wide range of creative effects in a simple interface.

Exposure simulates efffectis such as discontinued films, dark room tricks, and lo-fi camera quirks. Popular classic films are accurately simulated, like Kodachrome, Polaroid, and Panatomic-X, claims Alien Skin, as is the ethereal glow of black & white infrared film, and now colour infrared.

New texture overlay effects are built from high resolution photos of light leaks, dust and scratches, and borders. This helps add detail to new presets for alternative photographic processes like cyanotype, lith printing, and wet plate photography.

Exposure 4 has a completely redesigned user interface and new controls. Black & White and Color Film are now combined into one filter so everything is in one place.

Here are some sample effects.

Exposure 4 will be available in February 2012 for US$249 (around £160). Owners of any version of Exposure may upgrade for $99 (£65). Exposure 4 supports Adobe Photoshop CS4 or later, Adobe Photoshop Elements 9 or later, and Adobe Photoshop Lightroom 2 or later.
