OM System Tough TG-7 - Raw preview on PhotoLab 7 looks grainy when compared to OM Workspace

I occasionally use an OM System Tough TG-7. I know it’s a point-and-shoot camera, but it does shoot in raw mode. I expect DXO PhotoLab to process raw images of this camera with at least the same results as the free software provided by OM System, which is OM Workspace. Please see the screenshots of unedited photos. When opened in PhotoLab, the auto-applied preset for the raw image is “DxO Optical Corrections only”. There’s no difference in quality if I apply the “No correction” preset. The raw image in PhotoLab looks grainy - more noise than when opened in OM Workspace. When opened in PhotoLab, the unedited JPG version looks less grainy (less noise) than the raw image.



Did you apply any DeepPRIME noise reduction ?

The screenshots are of the unedited photo, I did not apply any noise reduction.

Unlike the OM software, PL only does what you tell it to.

Do you know that OM Workspace makes changes upon opening an image? I tried opening my image in ON1 Photo RAW 2024 and it looked better that it does in DxO PhotoLab 7.

What you see is not what you can get at best.
Try to process your raw with Deep Prime, as Joanna said, and compare the resulting JPG with what you get with the other softwares.
Unless you zoom at > 75%, PL doesn’t display the effect of noise reduction. And for Deep Prime, you can’t see the effect on the whole image without processing it.

Does OM Workspace automatically apply all the in-camera jpeg settings to raw files similarly to Canon’s Digital Photo Professional and Nikon’s NX Studio? If so that would account for why the raw files initially opened in OM Workspace might look better than unfinished raw files in PhotoLab.

Let’s look at this a slightly different way.

I opened the raw file and applied Deep Prime XD. Then I exported it to Photoshop. Compare the screenshots (both screenshots are views of the image at 100%, the green doors are a handy area to compare). Though still noisy, the image in PhotoLab looks better when Deep Prime XD is applied than when no edits are applied. The image in Photoshop has very little noise - surely Photoshop does nothing to an image that’s simply opened.


Basically, why does an image exported from PhotoLab to Photoshop look better in Photoshop (little or no noise) than in PhotoLab (noise)?


Because PhotoLab’s denoising isn’t fully applied until export.

Joanna, thank you for that piece of information. It seems to me that every edit one makes in an editing tool should be visible within the tool.

It does seem ridiculous to me that this is the case: there are four types of denoising, how on earth are you to know when you’ve selected a type that is too much?

DeepPRIME is “intelligent”. Just use that all the time, no matter what the ISO. Only on rare occasions resort to XD for very high (20,000 ISO)

DeepPRIME and DeepPRIME XD are applied to images when they are demosaiced during export.

You can use the small preview window to see the different NR types and you can also preview different areas of the image. DeepPrime is very CPU/GPU intensive and is only applied to the full image when you export. DeepPrime is applied during the demosaic process and it would take too long to apply each time an adjustment is made to the image.

If you have a computer with a powerful graphics card, you can use Deep Prime by default (any ISO) and DP XD when more details are needed at very high ISO.
Prime is still in the list, but it uses only the processor and it’s quite slow, with a result that is not as good as DP.

because deep prime takes a lot of processing it would slow the whole program down having to preview all changes - that is what the preview window in the denoising menu is for.
