Disclaimer: I'm no photography pro and I far from have a deep technical understanding of it but ...
Surely you want your exposure to remain in the stack at a bare minimum. Just like if taking a photo but plan on editing it in raw, you still expose the photo first and that's your starting point right?
It's something that always confuses me haha. Especially that AcesOT +1 stop of exposure thing.
I'd love someone to point me in the direction of a tutorial where someone takes a linear render and tonemaps it in Fusion/Resolve (ideally Fusion) and gets it back looking similar to how it did in the Frame Buffer before disabling the stack.
The way I see it, if editing the linear untonemapped image is akin to editing a raw photo, then the frame buffer is akin to the screen on the back of your camera. Its giving you a preview of the tonemapped raw render/photo. You then take that render/photo into your editor of choice (fusion/lightroom etc) and tonemap it using the flexibility of the tools in that editor. But my point is - your raw photo still relies on the exposure you set when taking the photo right? I appreciate the idea of RAW is that you can alter whatever you want after the fact, but you still want as close to a correctly exposed starting point as possible right?
What am I missing? I want to be educated .... hit me with it
Basics of HDR?There's really no 'consumer' digital camera with HDRI sensor available. Last I checked, 14bpc was max. (?)
RAW is just standardized industry image capturing format but still 'lossy' (minimally processed) in this regard.
To create HDRI with consumer camera, multiple exposed shots need to be combined into single image.
Virtually, Corona engine processes light transporting simulation in parallel universes, either w/ Adobe RGB or ACES color space and depth of 32bpc. (Results highly depend on 'Creators' input).
So, to express intent, display 'vision' or just tele-vise idea, adapting all gathered information/data that is considered influential to another being's experience, using certain medium to best of abilities is must (
Know thy tech/industry). Then, depending on capital/budget, results are cut, clamped and filtered down for 'big, lovely eyes' attention and consumption, to 8-12 bpc :)
Here's where
"Tone Mapping Operators" (docs) come to help.
Personally I use many different ones, depending on style I'm after and mood I'm in. Keeping it linear as much as possible and 'till the end is my preferred way. As for some shit and giggles comparison, IMhO, human vision's dynamic range surpasses 160bpc. Depending on food, mood, age, skill, tear and ware... But note that ALL OF THIS HERE is just discrete 'digital-shit' measure, excerpt from 'vision of reality' in an infinite analog spectrum. Avoid distractions. Fix ADHD w/ OCD. :P
