ELinBC Description

[ Main Manual Page ]


ELinBC_v1_86 Download

A Color-correction tool that works best when used on linear float images (its contrast slider is especially geared towards them) and removes the regular BC tool's limitation of not being able to adjust red, green or blue separately. Requires Fusion 6.31 or later. You can download version 1.65 without full DoD support which still works with older releases.

The Fuse is similar to the Brightness/Contrast tool, but does the operations in a different order (which is the one found in Nuke's CC node making it possible to transfer grades between applications). It lacks highlights/shadows controls, these can easily be implemented using a Ranges mask.

Gamma, gain and offset (brightness) can either be a single slider or split into red, green and blue, which basically gives you the power of a CC or ColorGain tool on demand. The single slider acts as luminance slider for the RGB values so you can combine RGB, reset the single slider to 1.0 and then turn it into three separate sliders again. This allows for tinting that doesn't alter the perceived brightness.



Main Inputs

The following inputs appear on the tool's tile in the Flow Editor:

Input Image:Node_Input_Gold.gif
Source image to be color corrected. Required.
Effect Mask Image:Node_Input_Lavender.gif‎
Defines the areas where the grade is applied. Optional.





Controls Tab


Saturation

Slider control. Reduce or increase the saturation (scaling of UV channels in YUV color space).

Contrast

Slider control. The contrast slider doesn't modify white and black points but applies a gamma curve that "rotates" around 0.18 instead of 1.0. If you have ever tried to increase contrast by playing around with gamma and gain at the same time, this is for you. This slider only makes sense for linear images (gamma removed using the Gamut tool or CGI rendered with a gamma of 1.0).

Gamma

Slider controls. Applies a power function (gamma correction).

Gain

Slider controls. Scales (multiplies) the color channels by the given factor(s).

Offset

Slider controls. Adds a constant value to the RGB channels (also called "Brightness" in Fusion's BC tool).

Gamma RGB / Gain RGB / Offset RGB

Checkbox controls. Toggles between a single slider or three separate color sliders for each of the three operations. Note: If you use this Fuse on a mono image (i.e. a mask tool), the output will be a four-channel RGBA image if one of these checkboxes is enabled. This allows you to tint a roto mask.

Pre-Divide/Post-Multiply

Checkbox control. As with all color correction tools, this is needed for images that have an alpha channel.

Affect Canvas

Checkbox control. Defines whether the canvas color should be affected by the color correction or whether it should be kept the same as in the input image.
