Filters & Adjustments =============================================================================== These group includes nodes to improve image quality and color grade, as well as tools for image analysis and value manipulation. Vibrance -------------------------------------------------------------------------------- .. image:: _static/filters/vibrance.jpg Works like in the filter in Darkroom and many other 2D editors. Adds more saturation in the less saturated areas, and less in the more saturated ones. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Intensity Strength of the effect Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Vibrance by Luminance -------------------------------------------------------------------------------- .. image:: _static/filters/vibrance_by_luminance.jpg Works like Vibrance, but also takes into account brightness. Lighter areas will get less saturation (or even get desaturated) while darker areas get more saturation. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Intensity Strength of the effect Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Channel Transform ------------------------------------------------------------------------------- .. image:: _static/filters/channel_transform.jpg Apply different transforms to each image channel. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image X Horizontal position Y Vertical position Angle Rotation Width Channel Width Height Channel Height Opacity Opacity Mask Mask out areas of the effect ========================= ======================================================== (these settings are repeated for each channel) ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== High Pass Filter ------------------------------------------------------------------------------- .. image:: _static/filters/highpass.jpg This node can be used for many things, just like in 2D editors. Google "High Pass Filter" to find more ideas and tutorials. ========================= ======================================================== Inputs Description ========================= ======================================================== Intensity How much of the effect is applied Radius How much blur to use in the effect Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== High Pass Sharpening ------------------------------------------------------------------------------- .. image:: _static/filters/highpass_sharpening.jpg Sharpens the image using the High Pass filter. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Intensity How much of the effect is applied Radius How much blur to use in the effect Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image Edges Edges from the image ======================= ======================================================== Clamp -------------------------------------------------------------------------------- .. image:: _static/filters/clamp.jpg Clamps brightness to be between the maximum and minimum. You can use this node to get animations/video in legal range for broadcast, or to clamp an input value for a node group. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Maximum Clamp high values to this number Minimum Clamp low values to this number Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Highlight out of Range -------------------------------------------------------------------------------- .. image:: _static/filters/out_of_range.jpg Colors pixels that are above the maximum or below the minimum brightness. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Maximum Values above this number will be colored Minimum Values below this number will be colored Above Max Color Color for values above maximum value Below Min Color Color for values above minimum value ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image Above Max Mask Mask of values above maximum Below Min Mask Mask of values above minimum ======================= ======================================================== Shadow gain -------------------------------------------------------------------------------- .. image:: _static/filters/shadow_gain.jpg Pump the shadows. They can also add a little extra to each of the RGB channels (it can be used to make shadows colder for instance). ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Intensity Strength of the effect Tweak Blue/Green/Red Increase or decrease the effect on each channel Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Light gain -------------------------------------------------------------------------------- .. image:: _static/filters/light_gain.jpg Pump the highlights.

Each setting includes a "Mask Tweak" value to modify the mask. ========================= ======================================================== Inputs Description ========================= ======================================================== Image Original image Highlights Threshold to consider a value a highlight Highlights Mask Tweak Tweak mask by changing contrast Mid-tones High Threshold to consider a value a mid-tone (maximum) Mid-tones High Mask Tweak Tweak mask by changing contrast Mid-tones Low Threshold to consider a value a mid-tone (minimum) Mid-tones Low Mask Tweak Tweak mask by changing contrast Shadows Threshold to consider a value a shadow Shadows Mask Tweak Tweak mask by changing contrast Mask Mask out areas of the effect ========================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Highlight Mask Greyscale image for highlights Mid-tones Mask Greyscale image for mid-tones Shadows Mask Greyscale image for shadows ======================= ======================================================== Color by Luminance -------------------------------------------------------------------------------- .. image:: _static/filters/color_by_luminance.jpg Colorizes the image based on the base hue, and shifts it according to brightness. Hue goes from 0.0 to 1.0. Both ends are red. Shifting is done by adding to the base hue. For instance: A base hue of 0.5 with a Max hue shift of 0.25, would yield hues in the range 0.5-0.75. This node is specially useful for coloring greyscale images with a more realistic approach than just using a single color. ======================= ======================================================== Inputs Description ======================= ======================================================== Image Original image Base Hue Hue to use when coloring Maximum Hue Shift How much to add to the hue from brightness changes Soften Soften hue changes Saturate Saturation of colorization Luminance Influence How much luminance influences hue Saturate by Luminance Saturate or desaturate using luminance Mask Mask out areas of the effect ======================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ======================================================== Two-Tone Mixer -------------------------------------------------------------------------------- .. image:: _static/filters/two_tone.jpg Changes the tones of both lights and shadows without changing their brightness. ======================= ======================================================== Inputs Description ======================= ======================================================== Image Original image First Tone Color(s) to mix with shadows Second Tone Color(s) to mix with medium tones and highlights First Tone Influence Mix factor for first tone Second Tone Influence Mix factor for second tone Mask Mask out areas of the effect ======================= ======================================================== ======================= ======================================================== Outputs Description ======================= ======================================================== Image The resulting image ======================= ========================================================
