Size – Specifies the size of the filter as percentage of the image's diagonal. See the Size example below.
Bloom – Controls the blend between bloom and glare. A value of 1 forces bloom to be applied to full extent and without any glare. A value of 0 removes the bloom completely and applies only glare. Values in-between blend the two effects proportionally. See the Bloom/Glare example below.
Intensity – Multiplier for the bloom/glare source bright pixels. Increasing the value can boost the effect by simulating up to 20 times brighter source. Values lower than 1 can be used to produce subtle bloom/glare from overbright sources.See the Intensity example below.
Threshold – Sets a minimum value for the rendered pixels to be considered as lens effects source. The Bloom/Glare effect will be generated only regarding pixels with larger value than the specified threshold.
Effect Rotation – Rotates the final result effect, regardless of this is a filter image or a procedurally created one.
Cold/Warm – When enabled, the Bloom/Glare effect will be toned to cold hues. When disabled, the effects will receive warm hue. The hue shift requires Saturation values larger than 0. See the Cold/Warm & Saturation examples below.
Saturation – When the value is set 0, the effects use the original hue of the bright pixels to create bloom and glare. Larger values intensify the hue set with the Cold/Warm option. See the Cold/Warm & Saturation examples below.
Hardware Accelerated – Enable to calculate lens effects on the GPU. When multiple devices are present, V-Ray will prioritize the best one available.
Effect only– When enabled, only the effect is passed downstream allowing you to use the effect on other footage.
Verbosity– Specifies what type of messages will be printed in the log.
Clip to format– When enabled, if the bounding box is at or inside the format, don't enlarge the effect past the format. This avoids creating oversized images that aren’t used.

The Aperture Preview panel is loaded by default, but can be minimized like the other Aperture groups. The aperture shape shows the result of the applied lens effects.
