Exponential Blur

Brief Description

The Bloom filter sums multiple blur filters of different size, resulting in a larger but sharper glare than a simple blur. It is similar to applying \"Count\" separate Blur modifieers to the same input image with sizes 'Size', 'Size''Ratio', 'Size''Ratio'^2, etc., and averaging the results.

Controls

Parameter / Script Name	Type	Default	Function
`Enabled / enabled`	Boolean	On
`Red / process_red`	Boolean	On	Enable the red channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
`Green / process_green`	Boolean	On	Enable the green channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
`Blue / process_blue`	Boolean	On	Enable the blue channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
`Alpha / process_alpha`	Boolean	On	Enable the alpha channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0
`Size / size`	Float 2D	0, 0	Maximum blur size applied. Higher values extend the edges of thhe mask further.
`Count / Count`	Float	5	Number of blur kernels of the bloom filter. Higher values give a wider tail. A count of 1 is just the original blur.
`Ratio / ratio`	Float	2	Ratio between successive kernel sizes of the bloom filter. A ratio of 1 gives no Bloom effect, just the original blur.
`Bounding Box / rod_mode`	Choice	Expand	- *Expand* - *Crop to format* - *Same as input*
`Filter / filter`	Choice	Gaussian	- *Gaussian* - *Box* - *Triangle* - *Quadratic*
`Border / border`	Choice	Repeat RGB Black Alpha	- *Repeat* - *Black* - *Repeat RGB Black Alpha*
`Crop To Composition Format / crop_source_to_comp`	Boolean	On	Useful to increase performances when doing large blurs of the size of the composition if you don't care that the intensities outside the comp get properly blurred.
`Downscale Threshold / downscale_threshold`	Float	15	When the size of the blur exceeds this threshold, the image is downscaled before blurring and upscale in output, which approximates what the blur would do a much faster speed. Increasing this value increases quality at the cost of processing speed.
`Mask / mask`	Image	-
`Mix / mix_with_source`	Float	1	Dissolves between the original image at 0 and the image with the effect applied at 1
