Questions about HDR Wheel Use

Hello!
I've done a quick search, but did not find the exact information I was looking for,
but I apologize in advance if this has been covered previously!

I have just started diving in to the HDR wheels, but I've got a few questions about them.

1 - What would be the difference functionally between using the HDR zones as opposed to just using bezier curves with anchor points in similar tonal ranges?

2 - It's my understanding that the HDR wheels expect to see the Davinci wide gamut color space?
If you are working with log footage in the standard Yrgb color space, would it be advisable to use HDR wheels after a normalizing curve?

3 - Just generally speaking, how are some of you incorporating these HDR wheels into non HDR delivery material? Where have you found them to be most useful? I'm very intrigues by the idea of using the HDR wheels for controlling the tonal saturation ranges, but again, not quite sure how these are different than using the previously available curves such as lum v sat.


Thanks!

Jim,
Thanks for your reply.
I did not feel that was the appropriate sub for my question as mine is workflow related and the sub you link seems to be specifically geared toward bug reports -
"To help keep the v17 beta items separate from the regular forum topics, please use v17 beta sub forum for all your reports on v17 beta items."

Mine isn't a report, but rather a question on how different tools work. If a mod feels I posted in the wrong area, by all means, please move it to the correct one. But my question still remains
.
Anyone else who can input on this??
Thanks!

i prefer them to curves - mapping to a color surface is a huge advantage, as is the ablity to toggle highlight mode to show the region you are working within

maybe try playing with a grey scale useing both curves and zones, then try again with an image with awide dynamic range and a range of skintones

I think it's for all questions when you're using version 17. As those wheels only exist in 17...

i think Daniel has a point as the "beta" sub foums are deleted after the release, and this is not beta related, more about workflow and may well live on past v.1x

and more thoughts about zones -vs- curves
- haveing exposure and sat inside in one ui is far faster than togeling between the related curves ui's
- being able to adjust regions/zones with my eyes on the hero mon is preferable to mess'n with the UI then looking up to vaidate the choices, back down to mess with the ui, on and on....

but i rarely use curves anyway
and rarely use anything but a color surface adjust color

Dermot,
Thanks so much for inputting on this!
That makes total sense to me to work in one UI window.
Very much a good point on that! I tend to separate my nodes when they use different UI pages so that
I don't confuse myself with adjustments that have been made on a node that are not readily apparent, but this does help keep the confusion to a minimum in that regard.

Thanks again for chiming in!
