For a while now I've been trying to find a raw workflow in Linux using open source software and some work around like wine and Adobe dng converter and while I've managed to get images I found most to be lacking punch, were flat dull and washed out and other stuff, I've mentioned on this thread.

I've also seen other mentions of flat images coming out of the dng conversion throughout my searching on the net.

I've noticed when using my windows box, DPP produces better looking previews and so on, meaning I was never really satisfied with my workflow on Linux.

There could be a number of reasons for this I suppose, Canon actually supports windows, Mac and Adobe and their own DPP and works with them...

Adobe could say, no free lunch with the dng converter, slightly mute the conversion and if you want better color accuracy, pay up!

For the most part Linux software is open source and some standards are reverse engineered, or Linux just don't support the profiles or what not.

Anyway, I thought this was interesting when I pulled up the straight out of the camera processed jpg (top left-hand image) and the dng converted raw file in rawtherapee bottom. I took a screenshot of things. Didn't pull up the edited dng file because it wasn't much better then the dng.

The jpg looks much better. Not sure what is going on. Maybe white balance, maybe in camera sharpness and saturation and other in camera settings.

Maybe the dng is supposed to look like that and I've been used to seeing the metadata pulled into and applied to the raw images in DPP on a windows PC and maybe my usual editing style I've been using for years with DPP / Lightroom and older windows version (7) and an older 5dmkii has left me out of touch with editing. I do understand that raw and dng files need developed, but the development I've done with them using Foss has left me underwhelmed.

Makes me wonder if trying to use Linux for this is more of a hindrance and I'm really shortchanging my self, images and gear... Or I can just shoot jpgs

If you look around on POTN, you may find a number of posts where people find that Canon's own DPP handles Canon RAW files far better than LightRoom or anything else out there. It really shouldn't be too surprising. With any third party software they are trying to be able to interpret every RAW file out there from every manufacturer. Canon is building it's files, it's software and the sensors all under one umbrella and knows a thing or two about all of above. With DNG maybe it's taking it all even further, further introducing the ways that a RAW file might be misinterpreted.

DPP is free with your camera!

Might be a while before I get around to that unfortunately. I don't even think I know where to host them. BTW what distro are you using?

Also found an interesting little tidbit on the R and that is if you happen to transfer files via the Canon connect app to your phone or something then disconnect, power off the camera for a bit, sit it in the bag and forget about it for a while, seems "off" don't turn the wifi and Bluetooth connection off and thus sucks down the battery... One would think it wouldn't be necessary to disable the wireless functions when turning the camera off.

IIRC WiFi and Bluetooth are left on so your phone can wake the camera. It would be nice if it were optional to auto-disable them.

I set it to "on". It had been set to "off" by default I think. It did not cause problems except on the long lenses with teleconverters. It's sort of the oppposite of what the manual that John excerpted above says. But it seems to work now. It is raining like crazy and dark so it was only quick test so I will spend some more time at it tomorrow outdoors and make sure it works better now. It did in the fast test I did a little while ago.

Thanks everyone!

I just tried again in the daytime with the R and the 300 2.8 and 2x and it is working much better now! You guys are great!!!!

As an aside I wrote to Canon Tech services and the reply was most unhelpful. Supposedly they are referring it to a tech group to try to replicate the problem and they will get back to me. We will see what they say.

As far as DPP previews go. Not sure if you are are about Quick Check. DPP's downsizing algorithm for 'fit to screen' display is very good - contrasty which creates the illusion of sharpness. It is like viewing them on the cameras LCD. Around 2007 give or take a year I spent months trying to figure out how to get final Jpegs using multiple developers to look as good as they did in Quick Check - Full Screen. For a real comparison don't use Quick Check and view both at 100%. Make sure capture sharpening is applied to whatever you are comparing DPP to.

That being said DPP is excellent and developed for Canon by Canon. I got LR in 2011 and since then I have always culled my files using DPP Quick Check -Full Screen to delete unusable and unwanted files before importing to LR.

IMO DPP lacks export sharpening. If I use "convert and save" LR's export screen LR blows DPP out of the water. This is not to praise LR. It applies to any developer that offers export sharing. Before I got LR I used DDP as my main developer but I always sent files to PS for final sharpening and resizing. Today if I was not using Adobe products I have something like Affinity or some other editor for the final steps.

DPP and LR at 100% before export. DPP with DLO and LR with Texture and Clarity adjustments. I could have added more sharpening in DPP. Default is 3 but I think it is 4 now. This is at 3.

@wxjef:

I use Ubuntu 18.04, I've been with Ubuntu since 2009 (9.04).

To transfer large files go to

We Transfer (https://wetransfer.com​/). You don't have to be a member, or subscribe. All you need to know is my e-mail address so I get a notification. I will send my e-mail address in a PM.

Nice to see someone else use Linux around here! What distro?

I use Linux also (debian). I use adobe converter under wine to move from cr3 to dng, then I use rawtherapee to develop my dng files.

I get results that are much better than those that I get under windows with DPP. The trick is to let rawtherapee use the dcp color profiles for canon eos r (file "canon eos r camera faithful v2.dcp" in particular) that are provided with the adobe converter, together with the lens profiles also provided by canon (lcp files).

Now I am on a trip without my PC, but I plan to make a detailed tutorial on my setup ASAP, for those interested.

Notice that I also make good use of rawtherapee "dynamic processing profiles" which make my workflow quite fast and efficient. As soon as the image is imported in the rawtherapee editor, based on the lens used, the iso, and other parameters, the appropriate settings are applied (e.g. lens profile, sharpening level, noise removal, etc.) such that I have a good basis to start.

Again, more details later but I hope those of you that are familiar with rawtherapee may "interpret" my suggestions above. In particular those about the dcp and lcp profiles are fundamental to get the correct colors and avoid the "dullness" that sometimes affects rawtherapee conversion.

I use Manjaro 18 I believe, probably a bit bad since it's a rolling release, ended up on it due to my ryzen 2200g wasn't really supported by most other distros. The system is basically a test bed to see if I could make the move to Linux. It's been manageable but very frustrating and circular arguing for me a lot of the time.

Thought about trying Debian stable. Almost ready to scrap the idea and just stay on Windows, at least stuff should just work. Will keep mulling it over and testing but I don't know.

Hope the Linux chat is not too of topic

I also find it interesting some find Adobe a better raw processor, some DPP, some Linux users etc. I wonder why? User tastes? Different camera settings? Different hardware and drivers and software settings?

But I suppose even with film there was slight variations in each stock.

Gave it another go on the test image, this is a new edit on the "flat, dull, lifeless" dng file that Adobe dng converter spat out at me a while ago, that I complained about. Top one is the fresh edit, bottom square crop original. I am starting to think "user error" and not knowing the software.

In working with the images I think I forgot to change the while balance, and also tinker with the contrast and saturation, and, you know, in general not actually knowing how to use this pretty new to me software and cameras. So, yeah. More learning and testing then. The out of camera jpg still looks a bit better.

Wonderful set of animal photos with the EOS R.
Excellent

Here's my first published photo with my new EOS R. The eye focus actually works!
