RSA Color Correction
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 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 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 image. 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 those with strong casts receive a stronger one.
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.
