AI Denoise

[DBSilverfox]

Either I am doing something wrong or there may be a bug. I have turned on the function in Camera Raw that enables AI denoise to be applied non-destructively without creating a DNG. Brilliant.  If I open a raw file with photoshop, it opens with camera raw first, as expected - and there is the feature.  However if I open in Lightroom Classic > Edit in Photoshop2025, the raw file opens directly in Photoshop (it used to open in Camera Raw first). Then Filter >Camera Raw Filter then the feature is not there.

This cannot be right can it?

This is how it's supposed to work.

Edit in Photoshop does not open the Camera Raw dialog. The ACR plugin does open the file into Photoshop, but the settings from Lightroom are automatically applied and the rendered RGB result opens directly without a dialog. You've already made your settings in Lightroom, so there's no need.

The only time you see the ACR dialog is if you open as smart object, and reopen the smart object from Photoshop.

The ACR filter in Photoshop is something else entirely. Do not confuse that with the full ACR raw processor! The ACR filter is just a small subset and does not process raw files. It can only be used on alread rendered RGB data. It works just like any other filter in Photoshop.

As for the new "technology preview" version of Denoise, I have activated it but haven't really had time for any extensive testing. Lightroom Classic doesn't seem to accesss that new algorithm and seems to work as it has previously (creating a separate DNG).

Thanks for the response. My memory must be deceiving me regarding the Edit in Photoshop - I was sure it did before. But regardless.

This seems to be such a useful feature, negating the need for a huge dng file in addition to the raw file, that it seems absolutely ridiculous to confine the benefits to one specific workflow. Without trying to generalise, I am sure many photographers are able to do most of the processing in Lightroom and switch over to PS when specific tasks are required. Restricting this benefit exclusively to users who run the Bridge >Camera Raw>Photoshop workflow does not make any sense at all. I hope this gets incorporated in an imminent Lightroom update

At least I know it is not something I have not set, or am doing wrong

Not disagreeing there. But keep in mind that this is a technology preview, in effect, a beta feature, under development.

My guess is that they restrict it to ACR at this time because that's mostly used on a single image basis. Lightroom is more of a "power tool" for high volume processing - so if there are any glitches, the consequences can be potentially devastating.

Once this is ready for production, they will probably enable it for Lightroom as well.

I'm currently testing this as I use the Bridge/ACR workflow at my day job, and batching is going well so far. Eliminating the extra DNG is a good thing for me. Rikk already posted that this is coming to Lightroom in time.
