Imager Exposure - Arnold User Guide

Use the exposure imager to specify additional exposure compensation.

Input

Input points to the previous imager operation in the chain (so that you can stack them and apply multiple operations serially).

Enable

Enables this imager.

Layer Selection

Selects layers processed by this imager with a glob or operator expression. An imager can use a selection to determine whhich AOVs will be selected to be processed by the imager at render time. The selection is an expression that can consist of multiple selections concatenated by:

• or (union)
• and (intersection)
• not (negation)
• and not (exclusion)
• () for nested scoping

Each selection uses glob patterns and regular expressions and a node will be processed by the imager if the expression matches the node name. By default, glob matching is used unless the selection is in a regex quote, i.e. r'<my_regex>'. For example:

specular or diffuse

not r'sss_(direct|indirect)'

r'color_(mask1|mask2)' or r'mask[34]'
