Colour plays a huge role in how we perceive and describe the world we see, so its hardly surprising that one of the first things we want to do to a photograph when we bring it into Photoshop is to adjust accurately or play creatively with the colour in the image. Photographers in particular have long desired to reproduce traditional photographic processes digitally using Photoshop. PhotoKit colour provides a comprehensive suite of effects that let you recreate creative effects like black and white split toning and cross processing. All these effects are applied as separate layers so the user can make further variations, adapting each effect to suit their own tastes. But thats not all! With PhotoKit colour, you can enhance specific colours in your photographs. You can make skin tones less red or lighter. With the Blue Enhance effect you can darken a blue sky and enhance the cloud contrast. And with the RSA Gray Balance set, you can automatically remove colour-casts from almost any type of image.
PhotoKit colour provides the following effect modules:
Cross Processing provides 14 types of cross processing effects in varying strengths that match the conventional film techniques for processing negative film in transparency chemistry and processing transparency film in negative chemistry. Included are 6 Lab colour-based effects, which can produce vivid colour results, and also inverted Lab colour effects that simulate shooting with infrared colour film.
Colour Overlay offers a set of 9 different colour overlays that apply rich colour filters to any image and add a subtle split colour effect between the shadow and highlight colours.
Split Toning can be applied to colour or black and white images in RGB mode. The 12 split toning effects loosely match the conventional photographic processes used in the black and white darkroom. But the effects apply just as effectively to full colour images as well.
Tone Enhance is a set of effects which first appeared in the original PhotoKit plug-in and have now been updated and incorporated into PhotoKit colour. The 12 Tone Enhance effects allow you to increase or decrease the exposure and modify the image contrast in precise increments.
Colour Enhance lets you modify colours selectively in an image. For example, the Blue Enhance effect returns two layers that let you selectively darken the blues in an image and adjust the blue saturation. The Green Enhance effect lets you lighten the green colours selectively in a dark forest scene and boost the green contrast. Colour Enhance contains a total of 18 effects that include: Blue/Amber grads, Warm/Cool filters, plus grainy pastel and grainy contrast effects, which simulate shooting with high speed colour film.
CC Correction offers a set of 18 effects that match the conventional colour compensating filters that photographers have traditionally used to make small, precision colour corrections. These CC effects are optimized for the main RGB colour workspaces commonly used in Photoshop and they provide exact, reproducible colour adjustments, no matter which common colour space you prefer to use as your default workspace. The colour working spaces directly supported are: Adobe RGB, ColourMatch RGB, Pro Photo RGB and sRGB.
CT Correction produces larger colour shifts using 5 orange/warming and 5 blue/cooling filters. These are also optimized for the main RGB colour workspaces used in Photoshop, to provide exact, reproducible colour temperature shift adjustments.
RSA Gray Balance provides a revolutionary new type of automatic colour correction. RSA Gray Balance Standard is a fast general purpose gray balancing tool which will colour correct most photographs. RSA Gray Balance Fine offers a more accurate, but slower, method of colour correction for trickier images. And finally, there is a RSA Neutralize that can effectively zap any deep colourcast.
Like all PhotoKit effects, PhotoKit colour effects are non-destructive layer-based edits that never touch your original image data. Because they are layer-based, you can increase or decrease the strength by changing layer opacity, or make local adjustments using layer masks, so you always remain in control. PhotoKit colour will never modify the original pixels in your image so you are free to experiment and be more creative.
