The CameraXXL controls can be seen within the red frames on the Camera Raw dialog in Photoshop Elements.
The HSL / Grayscale tab sheet offers sliders for adjusting the hue, saturation and luminance of 8 different color areas. Alternatively you can also create a black & white verson of the image and selectively brighten or darken certain image areas.
The Split Toning tab sheet allows colorizing highlights and shadows with different colors thus creating a split or duo tone look.
The Lens Correction tab sheet contains controls for correcting lens distortions. You can do that automatically via a lens profile or manually remove distortions, fringes and vignetting.
The Effects tab sheet lets you (de)haze the image, add grain and an artistic vignette effect.
On the Camera Calibration tab sheet seven new sliders are added by CameraXXL. They let you adjust the hue and saturation of the red, green and blue channel as well as tint the shadows magenta or green.
The Presets tab sheet lets you save and apply presets of your favorite Camera Raw and CameraXXL settings.
