Photoshop: Better Noise Reduction

Can we have pro grade NR in PS - at least as good as ACR?

I don't want to have to resort to third party plugins for noise reduction, as they get blamed for so many of PS's bugs (many of which ail me). But being honest here, what's in PS now is truly competitively weak.

Can't the premier pixel editing software include NR at least as good as it's brethren products, Lr & ACR?

(Really, I think PS should include ACR within it, like a filter/plugin, where users can easily choose presets that affect multiple parameters; but that's another thread/request, which I've already made.)

I’m not sure how easily ACR’s noise reduction could be transferred into Photoshop as a Filter, but the request sounds reasonable.

One reason is they are controlling the rendering of the raw data into pixels.

Once you render data, there's a lot of toothpaste you can't put back into that tube. You've baked that cake so to speak. This is WHY you want to handle this kind of editing at the raw stage, in LR or ACR.

No, even on Tiffs ACR's NR is superior to PS's. Try it.

If that’s true, then use ACR keeping in mind, the processing path in ACR is quite different than Photoshop (linear encoded processing versus gamma encoded).

Andrew, I try to integrate ACR into my PS workflow, but it's very challenging. For instance, I begin with TIFFs with paths, but ACR strips the paths.

I work in a production environment (speed, quality and volume) and having to switch the ACR TIFFs prefs on and off all day long, usually discovering they are wrong when needed, is tedious and confusing.

But what I love about ACR are the presets: the ability to rapidly engage a series of effects at once to create a given look. Engaging sharpening and NR together is very beneficial, as is fill with blacks and contrast, etc. While it's possible to do similar with PS actions, it's less dynamic, holistic, and WYSIWYG. Ideally, ACR and actions wold work hand-in-hand, such that PS actions could call upon ACR presets.

And other than a mild intellectual curiosity, which you're welcome to indulge, I really don't care about the encoding under the hood, the truth is on screen and in print.

The issue is the workflow. NR should be applied almost first in image processing, long before a path comes into play. Before even capture sharpening. Ideally, NR would be applied to the raw data! Long before pixels are rendered.

I hear what you're saying, but I'm working with files that are developed with Leaf software, because ACR's sharpening isn't up to snuff for our needs. So truly ideal scenarios often don't exist, and we move on to "next best" alternatives.

Unfortunately, what I consider "next best" is tedious, and because of time/volume/workflow constraints, often unproductive. Tighter integration of ACR and PS would help a lot.

But barring that, PS image quality enhancements, like improved NR, would be an step in the right direction.

FWIW, here's a former topic about integrating ACR into PS. That would be the biggest boon. Would love to see it get some more votes:

This is true.
As far as I can see it, ACR / Lightrrom doesn't apply the NR on the RAW data, hence it could easily ported into PS as a filter.
