The other day I got a "bad allocation" error when trying to apply the filter on a 16bit AdobeRGB1998 image. Converted it to 16bit sRGB, same thing (bad allocation). Converted it to 8bit sRGB and it crashed Photoshop CS4.

After I restarted Photoshop it seemed to then have no issues applying GREYCstoration to 16bit AdobeRGB1998 image.

On that note, should your GREYCstoration plug-in have no issues filtering in color spaces other then sRGB?
