Ok, i did both comparisons, with fixed amount of passes (40) and time (1 min).

The adaptivity by itself does a pretty good job here. I assume that rays casted into black background in first couple of passes are somehow assigned to sample more important parts of the image later. I wonder how well it will behave in interior shots...

Sorry for spamming in your thread Romullus, but there is no official adaptivity thread yet (I am sure once it's out it will EXPLODE with tests and examples), so:

Great results...!

Quick question, more related to the denoising feature really - can Corona output a version with and without denoising at the same time? I think it would be ideal if we could blend between them for final renders in post, as some areas become warped during denoising.

Heh I asked exactly about this to Ondra when we talked recently, basically controls for aggressivness of filter, and blending of filtered and non-filtered in framebuffer. He said it's doable, but said it didn't yield positive results from his tests. But that's no definite no :- )

How I planned to use this, was to do this manually, output both filtered and un-filtered results, and mask them with mat-ID  pass for mats with little high-frequency details, like flat painted surfaces. There is no detail that I can loose in white ceiling, but I always have shit-ton of noise there.

Cool. I mean for us it's probably not that important at all to have the blending controls within Corona. I would just like to be able to paint between the normal and denoised versions in photoshop/AE etc like we do now - if a render is a little noisy we'll denoise it in LR then matte between the two in PS manually. Having a sophisticated method for masking might be beneficial too. For now it would be great if there was a simple checkbox "Save Denoised Version Separately" or similar, so we get two files to work with each time.

While i find adaptivity absolutely awesome, i have mixed feelings about denoising. On one hand, in animations like posted earlier, it could be godsend, OTOH i doubt that i will use it often on stills. I'm not a big fan of clinically clean images in a first place, besides i don't quite like those jpeg compression like artifacts after Corona's denoising. While those usually can be seen only in high zoom, it still leaves "dirty" image impression for me.

I think it could be awesome for high res product shots... When the image is almost clean, but needs to be completely clean... Especially when featuring glass..

I agree. But I think if we can simply paint mask between normal and denoised we could control this. The "dirty", "wobbly" areas are visible in some areas of that animation but not in others, so as long as you can easily control this it should still be super useful. I can see myself using it to remove speckles in certain areas, smoothing out noisy large glossy surfaces, spotlight reflections in floors etc.

I fully support this idea, would make batch rendering a breeze too.
Vray who?

Just a reminder, someone should fill request in appropriate board, if you want that feature to appear in Corona. I doubt that devs will surf through my wips topic ;]

but there is no official adaptivity thread yet

Can you make it? A thread for adaptivity on/off images?
