Highlight Compression Macros for Eyeon Fusion + Foundry Nuke

(1/8) > >>

racoonart:
Ondra was so kind to give me the function for coronas highlight compression and I made a little fusion macro from that. So you can render your stuff without tone-mapping and apply it later in the post.

Just copy the code to your flow window or save it as a .setting in your usermacro folder.
Btw, all macros should be used with linear (gamma 1.0) input!


[EDIT]
Captain Obvious added a macro for Nuke!
For download and more details see Post #6

[Another EDIT]
Added the Filmic Curve tonemapping as a separate Tool. Big thanks to Captain Obvious for the idea and the guideline ;)

Juraj:
I am more and more inclined to have a look at Fusion. The guys at Uniform shown it and it did seemed simplier than maybe I feared/expected (I have a nightmare even from opening Nuke).

I had a brief look at the script but still have hard time envisioning how it works exactly. I have very mixed feelings about the look it produces. Not that I liked Reinhard (quite opposite..) but there's something about it I can't put my finger at, and prefer to do the tonemapping through curves in post.

Captain Obvious:
Great, thanks! I implemented it in my Nuke tone mapper gizmo as well. I can post it if anyone's interested.


Corona's tonemapper produces exactly the same results as Reinhard tonemapping. It's just that the settings work differently.

Is that really so ? I thought the result with Reinhard became somehow more saturated instead.

racoonart:
Fusion is pretty easy to learn, imho way more intuitive than nuke. It's btw relatively easy to use nuke if you know fusion - the concepts are mostly the same - but the overall usage is a lot easier to learn by trying things out in fusion. Nuke has some pitfalls here and there which are simply not existing in fusion (or you don't notice at first ;) ) and scare new users. I love fusion and it's such a pleasure to work with it. I can't imagine to do my work in any layer based compositing program like AE (totally pain in the ass)

The tone-mapping stuff is something I use very rarely, never in max directly (just in corona while rendering and playing with the values). I always save my images linear and do curves in the post. For me it's just a very useful thing to be able to achieve the exact same highlight compression in fusion than the way it is in corona - in case I liked what I saw when playing with the values at render time (or my boss or client etc).
The problem with this kind of compression is (imho) the reduced contrast in the midtones. I tend to reduce the compression just to the highlights with little influence into the midtones (for the soft transition).

Why not, I'd appreciate if we could complete this thread for all different kind of compositing packages :) I'd modify the topic name then :)
