Title: PureRAW
Post by: David Eckels on May 09, 2021, 09:01:12 am
Purchased PureRAW after seeing a couple demos online. Set it up to use DeepPrime and gave it a whirl. First, LR converted, unmodified DNG images cannot be used as a source file; Strike One! Second, SOOC NEF files sometimes result in black frames. If I select a group of 10, for example, the first four DeepPrime frames are empty and black. This also produces a graphics card access error; Strike Two! When I asked DxO if I could have my money back, they said NO even though I had used PureRAW less than a week and it seems to be an obviously defective product; Strike Three!

I then tried the same files using the Prime setting, and everything worked fine. Even unmodified dng files were processed although DxO Support said it could not be done. I think it is irresponsible for DxO to release a clearly defective product and not stand behind it.

Below, Argentine cactus blossoms rendered with the Prime setting and exported as DNG to LR unmodified. Jpeg at 65% to get under the file size restriction.

Out of curiosity, why didn't you use the 30 day free-trial? You could have sorted all the issues and make a decision about the product before paying for it.

It does mention this in their support files for the product.

This is why they offer 30 day free trials.

Given that there's been criticism of DXO support and PL4 here in the past, it seems rather reckless to rush out and pay for a brand new (v1) product without testing it first when you have that opportunity.
You'll just have to hope they will fix some of your issues in future updates.

Thanks for the replies, folks. Yes, in retrospect, I should have used the 30 day trial. But, I assumed, given the reviews I'd seen, that it would be straightforward. Worst case, I'm out $90.
I didn't see anything about DNG in their support files. Caveat emptor!

Indeed.
Anyhoo, the Prime setting seems quite good, even on DNG files, as seen in the OP image.
Thanks again for the replies. Lesson learned. ???

It might be worth trying a demo for PL4 Elite and seeing if the problem with Deep Prime is there too on your system. If not you may be able to get DXO to offer you a licence swap/upgrade to PL4.

Deep Prime is pretty good and really the main(only?) reason to use it with LR.
From what I've read the workflow of PL4 -> dng -> LR ought to bring DeepPrime to LR with only slightly more complication than using Pure Raw, but with a lot more control over the settings.

PL4 states the DeepPrime can only be enabled on native RAW files. Same goes for Prime.
In my WF I run my (RAW) files first through  PL4 (Denoise and Optical Corrections only) and from there export them to LR as .dng for further processing.
I have no problem with that since I was told that denoising should be done as soon as possible and I only shoot RAW.

Sounds a good way of using DeepPrime. My trial has expired now, so I can't check, but can you run that workflow without optical correction, then do that in LR ?

Unreliable lens identification was the bug that killed PL for me, but I never bothered to consider just using it for NR only and outputting as a DNG to LR.

I never tried it but one of the standard presets is "No Correction". From there I would apply Deep Prime and then create my own preset.
In "Preferences" you can choose which preset will be automatically applied to new images.
You can define an automatic preset for RAW and another for RGB files (no deep prime)
So you should load the images, select those you want and export them. The preset should have been applied automatically.
AFAIK...

Thanks.
I'll probably wait for PL5 with a whooping big discount. They might even speed it up and fix some of the bugs by then ;-)

I've had no problems with Pure RAW and have incorporated it into my Lightroom work flow. Instead of importing in LR with my normal custom Sony A7RIII preset, I skip that step. I do my culling and deleting, select all and drag and drop them onto the DXO PureRAW icon in my dock, (I'm on a Mac), which opens PureRAW with the images. I then process everything in Deep Prime irregardless of their ISO, testing showed it to be the best option. It takes a while depending upon the number of images. I just go and do something else.

It does a great job! Perhaps a bit too sharpened but that's easily corrected.

I've experimented with high ISO images, like 25,600 and it is amazing. Almost no noise with excellent detail.

David, I haven't tried PureRAW, but from what I understand it is basically a stripped down version of PL4, which I use fairly frequently. And for what it's worth, on two different Windows 10 computers, I get PL4 to open and run DeepPrime on DNG files generated by LR all the time. I save out a new DNG file from PL4, and back in LR it acts just like any other RAW file, except that it now has the noise removed. The DeepPrime noise removal is generally supurb, though sometimes I get better results from Topaz Denoise AI if I play with its controls; it depends on the image. Either one is leaps and bounds ahead of LR for noise reduction.

My workflow is to convert RAW files to DNG upon import into LR. Then if I decide to use DeepPrime, that is the very first thing I do, by selecting File>Plug-in Extras>Transfer to DxO Photolab 4. Any changes you make in LR (including default settings, like sharpening & NR) will be ignored when it goes to PL4 (and, I assume, PureRAW). After running DeepPrime, I export to LR as a DNG file, which has the suffix _DxO added to the file name.

DeepPrime does use a lot of CPU or graphics card resources though, and I find it will occasionally fail if I have other programs running that compete for those resources. Try it with other programs closed, which sometimes cures a problem with DeepPrime failing. You mentioned that with PureRAW you are getting a graphics card error. Assuming PureRaw has similar settings as PL4, under Preferences>Performance>DeepPrime Acceleration, try changing the settings between Auto, CPU, and  your graphics card, and see if it makes a difference.

Why do you convert the raw file to dng before transferring to PL4? Seems to be an additional step
Is it not the same as transferring the RAW file to PL4 and getting back the DNG from there after denoising?

I convert all my RAW files to DNG upon import, whether or not they are going into PL4. The original raw files are saved for a couple of months in a separate folder in case they are needed. There are arguments for and against converting original raw files to DNG for long term storage, which you can read if you search around on the web. I decided a long time ago that on balance, the pros of converting to DNG outweigh the cons for me.

There are many advantages to the DNG format, a few disadvantages.

I see. Should have been clear to me without asking  :-\

Thanks

Thank you Andrew.
Very interesting and instructive articles (as usual)
