Differential D6544
Compositor: Exposure Node Authored by Aaron Carlisle (Blendify) on Jan 7 2020, 9:41 PM.
Details This new node increases the radiance of an image by a scalar value. This can optionally affect the alpha channel which makes the node work This is in hopes of removing the brightness node which additive which causes colors to get washed out:   Both images have the same white value.

Comment Actions The idea of D6546 and D6544 is to replace the current bright/contrast node. Before I get into fixing these patches how would this work as far as compatibility? The compatibility will likely be broken, the old node should be removed, it is broken and unfunctional and leaving it in the UI will confuse users. Comment Actions As mentioned in D6546: Compositing: New Contrast Node, don't add a new node for this. Also leave out the use_alpha option, multiplying alpha with exposure makes no sense. Comment Actions I don't mind renaming this node to e.g. Exposure - Contrast if that helps discoverability. Please add an enum to switch between the new and legacy algorithm, with default to new. Mixing old and new logic makes little sense to me. Comment Actions This patch does not need an enum as it only adds a new parameter at its default value this node matches the old node. Its my other patch that would require an enum. Comment Actions Great stuff, was looking for an exposure node today. Hope this gets added soon! Solved it like this which I think is correct?  Comment Actions I decided to make a new node rather than add to the bright/contrast node see D9677 for an updated patch. | ||||||||||||
