exposure
Multiply the child's brightness, like opening a camera's aperture.
exposure(gain: ArgSpec): PointwiseEffect
Import effects from shaders/std and use effects.color.exposure.
gain of 1 leaves the color unchanged, 0.5 halves it, 2 doubles it. Blacks stay black. Values pushed above 1 are not clamped, so a glow or bloom filter placed after this one can pick them up.
