— (Min/Max) Range: Defines the level of image tonality at which that zone’s adjustment starts. This value is expressed in stops.
— Falloff: Adjusts how softly the adjustment in that zone will blend into the image. A value of 0 results in an immediate transition to the adjustment created in the current zone, with the color adjustment being a sharper effect. Higher values will blend the current zone’s adjustment into the image more softly, resulting in a more gentle and seamless transition into the effect.
Customizing and Saving Presets
If you’ve customized the Zone graph in a way that’s potentially useful for other grading situations, you can save a preset of the Zone settings for future use. Saving, recalling, and managing these presets is simple.
— To save a preset: Customize the Zone graph to suit your needs, then choose Save As New Preset from the HDR palette Option menu.
— To load a preset: Choose Presets > Name of Preset > Load Preset from the HDR palette Option menu. A new preset will be saved.
— To update a preset: Load a preset, make any changes you need to from the Zone graph, and then choose Presets > Name of Preset > Update Preset from the HDR palette Option menu.
— To delete a preset: Choose Presets > Name of Preset > Delete Preset from the HDR palette Option menu.
— To select the default preset: Choose Default Preset > Name of Preset from the HDR palette Option menu. This preset will now be the one loaded initially into the HDR palette on startup.
Resetting Color and Zone Adjustments
In the HDR palette’s Option menu, there’s a Reset submenu with three commands, Reset All, Reset Color Adjustments, and Reset Zone Definitions, which are self-explanatory. These are important because, during the course of developing a grade, there will be many times when you’ll want to reset your color adjustments without changing how you’ve customized the Zone graph, or vice versa.
Additionally, each of the visible reset buttons in the GUI can be used with keyboard modifiers to specifically target what to reset. The master reset button in the HDR palette’s title bar resets the entire palette when clicked (similar to the Reset All command). However, using keyboard modifiers while clicking this button changes what’s reset.
— Hold down Command+Shift while clicking the master reset button to reset only the Zone graph’s Range and Falloff controls, without resetting your color adjustments.
— Hold down Command+Option while clicking the master reset button to reset only the color adjustments, while leaving the zones alone.
Both of these modifiers also work with the zone-specific reset controls found in the Wheels panel, letting you reset only the Zone controls or only the Color controls of each specific zone.
