Denoise and Exif data tests

[Kerro]

I have been having a play today with PureRaw 2 and 3 and numerous editing programs. My conclusions are mixed and what I expected. The image attached shows original CR3 raw file, Pure Raw 2 file and the Pure Raw 3 file. All 3 images kept their respective Exif data.
When put into PS Beta and did a crop on the images, all 3 came back with no exif data no matter which format I saved them in. PS Beta has 3 ways to save. I also ran the files through Affinity, Luminar 4 and On 1 Raw 2018 and did the same crop. All retained the exif data in all of the respective save modes. Maybe I am missing something in PS coz I cant get the Exif to stay put after editing the files.
The denoise from the Pure Raw software is pretty amazing as can be seen by the image.
Just thought I'd run these tests for you all, to give you a bit info you may not have known.

Image 1 is CR3, image2 is PureRaw 2 and image 3 is Pure Raw 3

Hi Kerro,

I use DxO PhotoLab Elite (same NR tech as PureRAW - basically), Adobe Lightroom/ Photoshop and the Topaz Photo apps - along with a bunch of other stuff.

Files are passed around between these (various workflows apply depending on what I'm doing) I'm not aware of any problems retaining the exif data.

A typical workflow would be - import raw file into LrC -> DxO PL (raw file sent via plug-in) -> LrC (processed DNG) -> Photoshop (TIFF) -> LrC (TIFF).

What file format(s) are you using?

Phil

(DxO NR is amazing and - IMHO - the best, though I still use Adobe Denoise and Topaz Photo AI in some instances).

Phil, I'm using DNG, Tiff, png and jpg, depending on which stage of processing I'm at.

Hi Kerro,

I've just sent a DxO based DNG from LrC to Photoshop (it goes over as a TIFF), then saved it back to LrC as a png and jpg. The exif data was retained.

In conclusion, I have no idea what's going awry in your case - but there should be a solution (I just don't know what it is)...

Phil , it appears the missing link is LRC. Although the purpose of the exercise was to put the PR2 and 3 files into PS, edit with a crop then save back out with PS. As soon as I edit a file with PS the save does not retain the exif data. Strangely, Affinity, On 1 Raw and Luminar 4 save every time.

Hi Kerro,

I've just imported one of our DxO DNG's direct into PS (via Camera Raw - not LrC) and saved this as a png and as a jpg. The exif was retained.

As far I'm aware the import/ export settings I'm using in PS are the defaults. (I'm using the standard Photoshop 2024, not the Beta).

(All very odd - if I can think of anything else for you to try I'll let you know, but in the meantime I refer you to my previous conclusions... ).

I am using PS Beta. I'll try my tests on the normal PS and see how I go. Thanks for your efforts and thoughts Phil, they're greatly appreciated.

Phil, after doing extensive testing in Photoshop, (not Beta), as soon as I save I still get no Exif data. The only info I do get is image size, how many MBs, 300dpi and 24bit. Even a straight import to PS and do nothing to it, and save it still shows no exif data. I even reinstalled and reset all preferences back to default. I did the same as you in your first line of your quote here but to no avail.

Hi Kerro,

How odd. I've just sent a *.CR3 file across to PS from LrC and then exported/ imported it straight back as a TIFF (no edits). The exif is there.

I also imported the same file direct into PS and then exported it as a TIFF. Opening the TIFF in LrC the exif was as shown in the first example.

I've also imported a *.DNG file (exported from PhotoLab Elite) into PS, exported that as a TIFF and imported that into LrC - exif data still there.

I can't explain why the exif data is getting stripped out in your workflow.

(My system: MacBook Pro M1 Max, macOS Sonoma 14.0, LrC 13.0, Camera Raw 16.0, PS 25.0.0).

Phil, I am using Windows 11 on a fairly high spec machine. The only thing I can think of is, I am a Windows Insider user so there maybe something in there that affecting my version of PS as the insider copies of Windows are not necessarily stable. However, I do have a MacBook Pro and a fairly recent iMac 27, so I may install PS on them, (if I can get the wife off it for a while), and see how I go with that.

Hi Kerro,

It's going to be interesting to find out what is causing the problem.

At the moment the only obvious difference is the OS (and it wouldn't be the first time that's been the issue).


The thing you've got to worry about is keeping your wife happy...
