Power Retouche Photoshop Plugins - an Introduction

By Sarah Hansson


Power Retouche markets 27 Photoshop plugins for photo retouching. The flagships are the sharpener and the Black & White Studio. The sharpness plugin is the first and only sharpening tool on the market that does not create the negative fringes regular unsharp mask creates. It lets you sharpen surfaces and edges separately. The BW Studio converts color to black and white with a full set of professional films to select from, as well as traditional multigrade. It also includes exposure correction and contrast editing. The BW conversion can be controlled with seven sliders representing how the colors of the spectrum are converted to grayscale.

Other popular Photoshop plugins include the Golden Section filter that draws the golden sections, golden spiral and other harmonic divisions on an empty layer for editing and composing your image. The white balance corrector uses unique ways to automatically calculate the color of the light in the image and correct for it. It also offers options for the most popular gray-cards and color checkers like WhiBal, Gretag, etc. The plugin: Ansel Adams Zone System for Digital divides the image into ten zones that can be edited for exposure, contrast and color.

The Toned Photos plugin lets you tone your photo like a traditional toned print. There are presets for Sepia, Van Dyck, Kalitype, Silver Gelatin, Palladium, Platinum, Cyanotype and Silver. The plugin copies the pigment distribution of the traditional prints. You can adjust the preset tone or create your own tone. The conversion from color to grayscale includes traditional colored lens filters (yellow, orange, etc.). Another set of plugins deal with problem solving: Chromatic Aberration and Color Fringes. The Chromatic Aberration plugin deals with transverse CA and longitudinal CA. The Color Fringe plugin deals with all other types of color fringes, in particular the dreaded purple fringe, but all color fringes can be removed. The purple fringe is a special fringe that appears at high contrast edges, where the light overlaps the dark as a purple fringe.

The Lens Corrector plugin corrects barreling, pincushion and panorama photos. The plugin can correct both symmetric as well as asymmetric distortions. Asymmetric distortion come if you crop a distorted image. Symmetric distortion can be corrected in the later versions of Photoshop, but not asymmetric or panorama. The plugin differs from other similar distortion correction tools in that it does not explode the corners. Another plugin worth mentioning is the Soft Filter. It is a digital equivalent of a traditional lens soft filter. You can adjust the strength and the spread of the softening effect.

There is a Photoshop plugin for creating realistic film grain. It uses fractal technology to create film grain. Other film grain emulators either generate noise or overlay an image of film grain onto the image. Neither is realistic nor fit all images. Power Retouche lets you edit the size and hardness of the grain. Both black white grain and color grain are available.

There is a plugin to remove vignetting in photos. Vignetting is caused by camera lenses, or the sensor, and can easily be corrected. The plugin not only fixes the dark corners, but also lets you adjust radial exposure and brightness. In addition you can control the hot spot and its contrast. Finally the Black Definition plugin should be mentioned. It lets you control and edit black content of colors as if it were a color channel (like R, G and B). The suite contains more plugins than can be mentioned here.
