Alien Skin Software has released Exposure 4, the new version of its photography effects plug-in for Adobe Photoshop, Photoshop Elements, and Photoshop Lightroom. Exposure is designed for accurate film simulation and a wide range of creative effects in a simple interface.

Exposure brings all the creative tools of film photography to the world of digital, such as discontinued films, dark room tricks, and lo-fi camera quirks, according to Tom Welsh, the designer of Exposure. Popular classic films are accurately simulated, like Kodachrome, Polaroid, and Panatomic-X. Exposure reproduces the ethereal glow of black & white infrared film, and now color 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, says Welsh.

Exposure 4 has a redesigned user interface and new controls that help you explore its range of effects or develop your own custom looks. Black & white and color film are now combined into one filter so everything is in one place. The new text search lets you instantly explore hundreds of presets. Simply mouse over one to see a thumbnail preview. To help you get started and for advanced techniques, the web site has a library of tutorial videos and example images.

Exposure 4 is available at for US$249. Owners of any version of Exposure may upgrade for $99. Free upgrades were automatically sent to everyone who purchased Exposure 3 directly from Alien Skin Software in November 2011 or later.
