Smart Refinement Filter is a Photoshop compatible plug-in filter for photographic images enhancement. This plug-in allows: sharpness and depth-of-field (DOF) enhancement, and noise (dust) reduction. Basic features are: Both: sharpness enhancement and noise reduction are associated together into the single plug-in. That simplifies an optimal result achievement, since usually a sharpness addition cause to noise boosting and vice versa - a noise reduction may cause to burring. The sharpness control is a multi-band. It allows separate adjustment of: - almost invisible elements, - weak visible elements, - low contrast elements, - normal contrast elements. The noise reduction is adaptive, that means it’s automatically fitting to each local image region. I.e. the noise reduction of Smart Refinement Filter is a content-dependant. User is only required to tune the average influence levels for: - sharpness softening - shady areas noise suppression. Automatic adjustment. As an alternative to manual tuning a user may simply define the source image quality and the desired output image sharpness, then whole parameters will be tuned automatically.
