<constant name="TONE_MAPPER_LINEAR" value="0" enum="ToneMapper">
Linear tonemapper operator. Reads the linear data and passes it on unmodified.
Linear tonemapper operator. Reads the linear data and passes it on unmodified. This can cause bright lighting to look blown out, with noticeable clipping in the output colors.
</constant>
<constant name="TONE_MAPPER_REINHARDT" value="1" enum="ToneMapper">
Reinhardt tonemapper operator. Performs a variation on rendered pixels' colors by this formula: [code]color = color / (1 + color)[/code].
Reinhardt tonemapper operator. Performs a variation on rendered pixels' colors by this formula: [code]color = color / (1 + color)[/code]. This avoids clipping bright highlights, but the resulting image can look a bit dull.
</constant>
<constant name="TONE_MAPPER_FILMIC" value="2" enum="ToneMapper">
Filmic tonemapper operator.
Filmic tonemapper operator. This avoids clipping bright highlights, with a resulting image that usually looks more vivid than [constant TONE_MAPPER_REINHARDT].
</constant>
<constant name="TONE_MAPPER_ACES" value="3" enum="ToneMapper">
Academy Color Encoding System tonemapper operator.
Use the Academy Color Encoding System tonemapper. ACES is slightly more expensive than other options, but it handles bright lighting in a more realistic fashion by desaturating it as it becomes brighter. ACES typically has a more contrasted output compared to [constant TONE_MAPPER_REINHARDT] and [constant TONE_MAPPER_FILMIC].
[b]Note:[/b] This tonemapping operator is called "ACES Fitted" in Godot 3.x.

<constant name="GLOW_BLEND_MODE_ADDITIVE" value="0" enum="GlowBlendMode">
