Glare Node
The Glare node is used to add lens flares, fog, glows around exposed parts of an image and much more.
Входы
- Image
Standard color input.
Свойства
- Glare Type
- Ghosts:
Creates a haze over the image.
- Streaks:
Creates bright streaks used to simulate lens flares.
- Streaks
Total number of streaks.
- Angle Offset
The rotation offset factor of the streaks.
- Fade
Fade out factor for the streaks.
- Fog Glow:
Looks similar to Ghost. However, it is much smaller in size and gives more of an atmospheric haze or «glow» around the image.
Примечание
Viewport compositing results will vary from CPU compositing due to different algorithms.
- Size (размер)
Scale of the glow relative to the size of the original bright pixels.
- Simple Star:
Works similar to Streaks but gives a simpler shape looking like a star.
- Fade
Fade out factor for the streaks.
- Rotate 45
Rotate the streaks by 45°.
- Quality
If not set to something other the High, then the glare effect will only be applied to a low resolution copy of the image. This can be helpful to save render times while only doing preview renders.
- Iterations
The number of times to run through the filter algorithm. Higher values will give more accurate results but will take longer to compute. Note that, this is not available for Fog Glow as it does not use an iterative-based algorithm.
- Color Modulation
Used for Streaks and Ghosts to create a special dispersion effect.
Johannes Itten describes this effect, Color Modulation, as subtle variations in tones and chroma.
- Mix (смесь)
Value to control how much of the effect is added on to the image. A value of -1 would give just the original image, 0 gives a 50/50 mix, and 1 gives just the effect.
- Threshold
Pixels brighter than this value will be affected by the glare filter.
