Is there a way to animate the Simple Exposure Value in the Corona camera?
-
Doesn't look like the keyframe button for Simple Exposure works. I did just test that the Photographic Exposure camera settings DOES indeed animate. As I was reminded recently by TomG, you need to add Photographic Exposure to the Tone Mapping stack and you must disable the Simple Exposure option. Now when you select the Corona Camera tag, you can adjust the ISO, Shutter and F-stop like a real camera. I was able to keyframe the f-stop from light (f/2.8) to dark (f/22) with ease. Hope this helps.

I found the same thing, you can animate photographic exposure (ty for adding the info on how to do that BigAl3D!), but not simple exposure.
-
basically no "Tone Mapping" on Camera Tag can be animated

Thank you all for your responses.
That's quite a pity, isn't it?
Will that ever change?

It is and I'm sure it will. I have reported it. ;)

This is the only way to animate exposure indeed but why it is not enough I don't understand?
It can be done by this way.

Any update on this at all?

Hi, not updates at this time but we do have it on our short list :)

I am not sure about C4D, but in 3ds Max you can create a Corona Camera, go to its Tone Mapping rollout, enable "Override", and then animate the values in the floating Tone Mapping window under "Edit".

Hey Maru,
Just tried this, but it doesn't seem to keyframe the Simple Exposure parameter. Unless I'm doing something wrong?
Cheers,

I'll PM you so that we don't spam the C4D forum. :)

Any news regarding this, it has been a while ? Really troublesome for archviz when you need to shoot many frames of different exposure levels overnight. Should we be expecting this any time soon? Using photographic exposure is the only alternative but it takes so much time to properly set it up cause it is not changing realtime. Feels like back to film days. :)
Hope that someone might reply,
Best regards

"Photographic exposure" renders fine in RT/IV (CRN v10.1).
PS. I use "ISO" alone as substitute for "simple exposure".

Good idea! but still not a real time change but yes a good substitute till then.
cheers

Could you open a new thread for RT/IV issue and post a simple scene, video, describing steps to reproduce, full specs... showing, exposing the bug.
IIRC, there was such a bug some time ago, but for now (v10.1) runs well...
Although during more intensive, complex workflow, C4D can and occasionally IR/IV does stall (can't keep up and doesn't refresh) as it seems it's still highly sensitive to hierarchical order when generative processing and procedural/ key-framed animations are involved. But then, on 2nd action IR/IV responds again. (?)
-
I am not referring to IR rendering. This can actually work with the photographic exposure just fine even in IR.
It is just a minor inconvenience that if you are using this workflow then if you want to adjust the exposure in a normal rendering you need to disable photographic enable regular and change it. Anyway there is not need of any bug to be reproduced, keyframing simple exposure cannot happen the program does not let you do that.
Ultimately, the problem for me with using iso is that when I want some of my images to include DOF I need to adjust the aperture and then compensate with shutter speed, you can do it of course it is just not so easy as a simple exposure value regardless of the aperture value.
Anyway, I hope it will be addressed in the future. I see no reason to continue this thread tbh.
It is honestly a very simple functionality.

Hi, not updates at this time but we do have it on our short list :)
Its more than 2 years and 2 full versions later since I reported this.
Will you ever get to this point your "short list"?
-
Since this is a feature request (really should have been moved on the forums, sorry!), I added it to the Ideas Portal where it can be tracked and conversation can be centralized: https://chaos.aha.io/ideas/ideas/CMAX-I-38
"Will you ever get to this point your "short list"?" is something we can't answer, everything gets re-evaluated every release and we don't know 100% in advance of planning a release what makes it into that release and what does not. The status of the Idea will update if and when it makes it into the plans for a release, so be sure to follow that :) Thanks!

Can hardly wait for it to be transferred from the feature list to the bug list in 2 years' time.
Just kidding ... :-)
