Simulates the effect of extremely overexposed highlights on film. Highlights above a specific threshold are blurred, brightened, and recomposited with the original. Unaffected regions of the image interact with the glow effect, but otherwise retain their detail.
Adjust this filter using the parameter controls in the Filters Inspector:
Amount: Sets the amount of the bloom.
Brightness: Sets the brightness of the bloom.
Threshold: Sets the luminance threshold at which the bloom starts.
Horizontal: Sets the distance of horizontal bloom.
Vertical: Sets the distance of vertical bloom.
Clip to White: Any color channel exceeding the maximum value of 1 is clipped to 1.
Crop: Sets whether the filtered image is sharply cropped at its original boundaries. When this checkbox is deselected, the filter affects the edges of the image.
Mix: Sets the percentage of the original image to be blended with the filtered image.
