Another standout feature in the CS4 version is the improved Post-Crop Vignetting. In previous versions, cropping an image would distort a vignette applied before the crop. CS4 solved this by applying the vignette effect after the crop was determined, allowing for artistic framing that looks natural and intentional.
Perhaps the most significant feature introduced in the Camera Raw version accompanying CS4 was the localized adjustment tools. Prior to this, Raw editing was largely global—you adjusted the whole image at once. The Adjustment Brush allowed users to "paint" exposure, brightness, or clarity onto specific areas of the image, such as brightening a subject's face or darkening a sky. The Graduated Filter mimicked the effect of physical glass filters, allowing for seamless transitions in skies. These tools meant that many images could be finished entirely within the Raw dialog, bypassing the need for complex layer masks in the main Photoshop interface. camera raw for cs4
