P: Reduce magnification in Enhance Preview window

Adobe rarely comments on product-development plans.  Any authorized information would most likely appear in this thread.

That was over nine months ago.  Any recent evidence anyone at Adobe is still "listening" or thinking about this?

but there's been no indication that anyone at Adobe is even listening.

There's evidence right here in this thread. @TheDigitalDog said he talked to Adobe and "They are aware that other zoom ratios are desired".

Adobe does read all the posts in the Ideas section, and they do influence future product development.  The more upvotes on an Idea, the more likely they'll pay attention (though votes are far from the only factor in their decision making).  This idea currently has 19 votes, but a fair number (probably at least 5 - 10) are from marauding bots that are flooding this forum with bogus votes.  So 10 - 15 real votes is more than most posts here get, but it isn't a huge number, compared to other ideas here (which have or have not been implemented).

I see there have been many requests for a 100% magnification level in the Denoise preview window.  Has Adobe ever addressed this?   Like many others, I find that the artifacts created at the (apparent) 250%-300% default "choice" make the preview almost useless.  Is there some technical issue that actually prevents this from being implemented?

Lightroom 13 now out and disappointed to see that the enhance preview window is still at the completely unusable 250% magnification. It's absolutely impossible to assess what either the denoise or the super resolution are doing to image sharpness at that magnification. I don't even bother waiting for the preview to load before clicking the Enhance button. I realise that there's time and effort involved in developing a user scaleable preview but surely switching it to a useful 100% from the ridiculous 250% would be a matter of seconds to implement?

> Another issue that adds to the confusion is that the Before preview does not include manual color noise reduction, which is set to 25 by default. So the Before preview should include manual color noise settings.

Any noise (Luminance or Colour) settings that you may have previously applied via the sliders are ignored. Therefore, it doesn't make any difference whether they're set to 0, 25 or  even 100, Denoise just treats them as 0.

I use a 24" 1920 x 1200 monitor, and always view at 100%  to assess sharpness, noise and other image detail.

The 250% preview is just confusing, and tells me very little. So I have to use trial and error to find the best amount setting, which is annoying, and time consuming when the process takes 3 minutes.

Another issue that adds to the confusion is that the Before preview does not include manual color noise reduction, which is set to 25 by default. So the Before preview should include manual color noise settings.

But it makes you wonder if Denoise is even aware of the manual color noise setting when doing the processing.

For my monitor, 100% is perfect for examining image detail, but for high resolution monitors, 200% is needed.

So maybe options for 100, 150, 200, and 250%. 100 and 200 at the very least.

I silently wish for variable zoom levels.

I can find no mention of the magnification amount Adobe are using in the preview detail panel when using Denoise AI but I do know it is well over 100%. It's more like 250% or 300%! This makes it hard for me to estimate how much to move the percentage slider as I have no interest in removing noise that can only be seen when viewing at this very high magnification. I want to be able to analyse the noise when viewing at 100%. As far as I can make out this is impossible. The zoom symbol on the window goes from fitting the whole image within the constraints of the preview window to 250/300% zoom and nothing in between. This is far from satisfactory for how I (and I would imagine most other people) judge image quality, noise etc. Of course, I can understand if some people feel it is necessary assess noise at higher magnifications than 100% but let's please have the option of the starting point in the detail window being at 100%. This is normal for all other denoising software I have used. As it stands the preview window is pretty much useless to me.
