RSA Color Correction

RSA Corrections
The RSA corrections provide a brand new way of automatically color correcting your photographs. They are intelligent color correction tools that use a proprietary Pixel Genius 'Rule Seeking Algorithm' to analyze the image, and based on this, apply a precise curves color correction. RSA corrections strive to preserve the tonal  balance of  the original image.  If your original image has a nice soft contrast, the RSA corrections won't try to make it more contrasty by reassigning  the endpoints. RSA corrections intelligently remove a color cast from most photographs, without being fooled into correcting colors that don't need correcting. That being said, there are some images, such as sunsets, which have color casts you definitely don't want to neutralize!

RSA and the Pixel Genius Toolbox (Macintosh)
If you select any of the RSA effects from the menu options in the Toolbox, Macintosh users will notice that the Toolbox will disappear temporarily while the RSA preview is being created.

The reason for this happening is due to certain limitations of the Adobe Dialog Manager, and as such, this is the only way we are able to generate a preview and maintain consistency of generating previews for all the effects within the Pixel Genius Toolbox.

RSA Neutralize
RSA Neutralize is a drastic effect designed to correct images with strong color casts such as the one above, where you wish to make the colors as neutral as possible. RSA Neutralize is the most powerful of all the RSA effects, but is generally too strong an effect to use as a general gray balance tool. Use it for removing the heaviest casts-if it you run it on an image with only a slight color cast, the results may be disappointing.

RSA Gray Balance: Standard and Fine
RSA Gray Balance is designed to handle color casts ranging from slight to extreme. It comes in two flavors: Standard and Fine. The Standard setting works well on most types of images. RSA Gray Balance Fine takes a longer time to process and produces a more accurate gray balance (though not necessarily a 'better' image) than the standard RSA Gray Balance. For those situations where you find the Standard Gray Balance correction is lacking, use the Fine Gray Balance. RSA Gray Balance Fine first executes the RSA Gray Balance Standard algorithm, and returns that result on a layer, then it makes a second, more detailed pass on the corrected image and returns a second correction layer for fine-tuning.

The intelligence built into RSA Gray Balance makes it ideal for batch processing, because the degree of correction is calculated for each image. Images with little or no cast receive a very gentle correction, while a stronger correction will be applied to those images with heavier casts.

RSA Gray Balance Fine: layers
For unattended batch operation, RSA Gray Balance Fine is the best choice if you're willing to save the images with the layers intact, since it incorporates RSA Gray Balance Standard. For those images where RSA Gray Balance Fine produces too strong a correction, you can reduce the opacity of the RSA Gray Balance Fine layer, or even delete it entirely, once the batch has executed. If you need to save flattened files, we recommend that you use RSA Gray Balance Standard instead, and as with all batch corrections that produce flattened files, we recommend that you don't overwrite the original images.

RSA Gray Balance Error
While unlikely, there is a chance that the RSA Gray Balance may cause the following error:


The reason for this error message appearing may be because the image already contains all neutral tones (and therefore does not need to be auto-corrected). For more information on this subject, please go to the section on PhotoKit Color Errors.
