Within HDR MAX adjustments are divided into correlated groups which can be turned on or off while editing an image. This feature increases performance while also allowing the effects of an adjustment to be previewed in either state to better guage the effectiveness of the adjustment in the image.
Tonal reproduction is the process of compressing the high dynamic range of a scene to a range that can be displayed on an output device or other medium, such as a computer monitor or paper. In HDR MAX, tonal compression is achieved through the manipulation of a set of adjustment parameters. This section describes each of those adjustments in detail.
The Intensity adjustment affects the level of tonal compression performed on an HDR image, and ultimately, the amount of contrast and tonal output.
The following adjustments affect the level of concentration of the Intensity adjustment for the highlights and shadows of an image. This provides greater control in situations where the Intensity adjustment may appear to be over-compensating in particularly light or dark areas of an image.
Note: Either adjustments maximum output is determined by the Intensity adjustments value.
The Highlights adjustment determines the level of tonal compression within the light areas of an image.
The Shadows adjustment determines the level of tonal compression within the dark areas of an image.
Magnitude simultaneously adjusts the detail and luminance enhancements of an image in relation to the level of tonal compression. Higher values generally produce more vibrant colors with greater detail.
Smoothing determines the distribution of detail and luminance enhancements of an image in relation to the level of tonal compression.
Micro Detail adjusts the small details of an image in relation to the level of tonal compression. Higher values will generally enhance the image by bringing out the small details, while lower values will soften the image and help avoid noise.
The Luminance adjustment adjusts the luminance of the HDR image.
The Saturation adjustment adjusts the overall saturation of the HDR image.
The Exposure adjustment adjusts the overall exposure of the HDR image.
The Offset adjustment adjusts the overall offset of the HDR image.
The Gamma adjustment adjusts the overall gamma correction of the HDR image.
The Lighten adjustment restores highlights affected by tonal compression. This adjustment has the most effectiveness when the Intensity level is set to high.
The Darken adjustment restores shadows affected by tonal compression. This adjustment has the most effectiveness when the Intensity level is set to high.
The White Point adjustment affects the percentage of light pixels that are clamped.
The Black Point adjustment affects the percentage of dark pixels that are clamped.
The Temperature adjustment affects the overall temperature of the image.
The Tint adjustment affects the overall tint of the image.
The Brightness adjustment affects the overall brightness of the image.
The Contrast adjustment affects the overall contrast of the image.
The Hue adjustment affects the overall hue of the image.
The Lightness adjustment affects the overall lightness of the image.
The Filter adjustments provide an extra level of control for fine-tuning an image. For better performance, it is generally best to use these only after the desired adjustments have been made in the Adjustments palette.
The Distortion adjustment helps correct images affected by barrel and pincushion distortion.
The Vignette adjustment helps correct images affected by vignetting.
The Midpoint adjustment determines the midpoint of the Vignette adjustment.
The Scale adjustment determines the scale of the image.
The Strength adjustment determines the overall amount of noise reduction applied to the image.
The Preserve adjustment determines the amount of detail to preserve in an image.
The Sharpen adjustment determines the amount of sharpness of an image.
Note: The Unsharp Mask adjustments can be used in place of this adjustment for finer tuning.
The Amount adjustment determines the overall contrast of edge detail in an image.
The Radius adjustment determines the size of the edges to be sharpened.
The Threshold adjustment determines the minimum brightness level which should be sharpened in the image.
