While I'm still arguing with myself whether or not I should switch my entire #photo workflow from #DigiKam editor to #Darktable / #Gimp for the 32bit float reasons… (there are also good reasons not to do so)

… I find myself liking the JPEG previews that #AdobeDNGconverter renders. (I use it in #Wine.)

I often use these JPEG previews alone. They can be extracted on the command line with dcraw -e.

The #RAW files of my #PanasonicGH6 are still not supported by the tools on my system, and since this is #Ubuntu #Linux and its beliefs, it is hard to get new major versions of your tools without getting a new OS entirely.

ORF-RAW from #Olympus camera looks exactly the same in Darktable or in Digicam as it does with #DNG in between. #Adobe does have a point here.

I really love #DigiKam. However, since #Gimp has learned 32bit float colors, I miss that in the DigiKam photo editor. I am tempted to open #RAW / #DNG in Gimp, which is then automatically stuffed into #Darktable for conversion.

The magic of floating point pixels isn't the huge color dynamics, it is that if you should happen to edit parts of the picture into over-exposure, you can easily get it back without damage in later steps.

#Lightworks, the #NLE / video editor I use, has set 32bit float to default for video.

McCarthy’s: the pink garage

The derelict McCarthy’s Garage as it was in 2021 in Schull, Co Cork. The building today is very different, but it’s still pink! I have a few photos of the old petrol pumps that stood outside the building somewhere on this site, going further back in time.

The slate roof visible on the McCarthy’s building is typical of traditional Irish architecture. Irish slate was quarried extensively in counties like Valentia Island in Kerry and was prized for its durability and weather resistance, often lasting well over 100 years when properly maintained, which explains why so many original slate roofs still grace Irish buildings today.

[Перевод] Почему в индустрии фотокамер такой беспорядок с форматами RAW, и что говорят производители?

Когда вы настраиваете новую камеру или даже делаете фото с некоторых смартфонов, перед вами возникает выбор: JPG или RAW? Фото в JPG изначально готово к публикации практически везде, в то время как RAW — это сырой файл с дополнительными данными, дающими широкие возможности для пост-обработки. Такая опция сохранения в RAW (и даже само обобщённое название RAW) в индустрии вроде как стандартизирована, но несмотря на это, в мире фотосъёмки единый формат RAW так и не утвердился.

Yay. So earlier I got my #photography import script to actually import the stuff from cloud. A few hours of coding later, it now does SD cards too, and will also convert raw files to #DNG (with help from dnglab).

I'm not going to call this release quality until I add a bunch of documentation for myself, and add all of the actual error handling. And bunch of logging and stuff. And THEN I'll add a bunch of new stuff I never got around to doing in the PowerShell version.

I'm currently YOLOing the final test (i.e. importing 13 gigabytes of photos I shot over the christmas trip. It's fine! The thing creates backups afterall!)

@hp Also, an die Verschlagwortung unter digiKam werde ich mich wohl nie gewöhnen, auch wenn ich damit umzugehen weiß. 🙄😁 Aber ansonsten ist es vollgepackt mit nützlichen Funktionen, die sehr angenehm zu nutzen sind.

Das einfache Konvertieren nach #dng nehme ich auch gerne zur Hand. Aber auch sonst kann man mit #digiKam schnell und einfach mit Rohbildern umgehen. Habs mir auf meinem Laptop auch installiert, obwohl der bei mir sonst eher nichts mit Bildbearbeitung/Verwaltung zu tun hat. Aber wenn ich längere Zeit mal nicht zuhause bin, kann ich dennoch schön bequem in meinen neuen Rohdaten rumfummeln. :smile:

I’ve been using the Process Zero feature in Halide for a while now, but I’ve just realised that I misunderstood how it actually works. I had thought that when I selected Process Zero and exported the DNG (RAW) file, I was still getting the benefits of the Process Zero feature. But it turns out that’s not the case at all.

Process Zero applies only to JPEG/HEIC files. When I export the DNG (RAW) file and edit it in Lightroom or Darkroom, it’s not a Process Zero shot. The DNG (RAW) file is just that—a (mostly) unprocessed RAW image. I never made the connection that Process Zero is entirely automatic and doesn’t involve any post-processing and the JPEG/HEIF was the finalised Process Zero image.

It makes sense now why some people are confused, just like I was. You select Process Zero in the app, take a photo, and then export either the DNG (RAW) or the JPEG. I just assumed the label applied to both, but it only works for JPEGs or HEICs.

What I didn’t understand is that Process Zero is supposed to give you a final image with no extra editing needed. I’ve seen posts labelled “Process Zero” that I thought looked incredible, but now I realise many of those shots were likely edited DNG (RAW) images, not true Process Zero outputs. It’s kind of a humbling realisation, knowing that I’ve been misinterpreting this feature the whole time.

To compare the two, I decided to head over to the Billie Johnson Mountain Lakes Nature Preserve to capture images in the DNG and HEIC formats. The air was crisp and cool, and the sky was overcast, casting a soft light over the autumn foliage. The temperature was just right for a peaceful walk—around 12°C—and the air smelled fresh like it had rained overnight. It was 9:38 AM when I arrived, and the trees were full of colour: vibrant reds, golds, and deep oranges, making for a perfect backdrop to capture the differences between the two formats.

I made sure to shoot three sets of images, saving both the DNG (RAW) and HEIC versions. I kept the ISO low to avoid unnecessary noise and allowed Halide to automatically handle the white balance and focus. While the HEIC would benefit from Process Zero’s automatic adjustments, the DNG (RAW) was left unprocessed, awaiting post-production in Lightroom Classic.

With the shots taken, I packed up, feeling eager to dive into the files later at home and truly see the differences between the detailed DNG (RAW) files and the more compressed HEIC versions. I took a closer look at the metadata of two photos I captured: one in DNG (RAW) format and the other in HEIC.

The DNG file, which is a DNG (RAW) format, is designed for detailed, uncompressed images. This means I have much more flexibility when it comes to post-processing. However, this advantage comes with a trade-off: the file is a hefty 14 MB, making it significantly larger than the 2 MB HEIC file. The HEIC format, on the other hand, is compressed, which allows for smaller file sizes, making it easier to store and share but I lose some detail and editing flexibility.

While examining the metadata, I noticed that the DNG file contains intricate details about colour matrices. This information is invaluable for DNG (RAW) editing software like Adobe Lightroom, allowing for precise adjustments. In contrast, the HEIC file doesn’t include such details since it's meant to be more of a finished product

Moreover, the DNG (RAW) file includes additional metadata about its format, such as the DNG version and details for backward compatibility, along with a more extensive Exif data block. The HEIC file, being optimized for efficient storage, has fewer technical details, focusing more on user convenience.

Here’s a comparison of the key differences between the two files:

For comparison, I exported the untouched DNG file to a JPEG and exported the untouched Process Zero HEIC to a JPEG. By untouched I mean that I did not make any changes to these DNG or HEIC images before conversion to JPEG.

For the processed DNG (RAW) image I then applied my edits in Lightroom: adjusting exposure, contrast, highlights, shadows, blacks, texture, and vibrance. I then used the AI-powered Enhance Details feature of Adobe Lightroom Classic before exporting the image to a JPEG. Here is the result:

As for the Process Zero HEIC, I intentionally left it unedited because that’s the point of Process Zero—you're supposed to get a final image straight out of the camera (SOOC). The reality? It’s unpredictable. The image preview on your iPhone will never resemble the final HEIC that Process Zero produces. Shots are either blown out or underexposed with no reliable way to ensure a great result.

I’d advise not using Process Zero if the photo is important to you. For instance, I wouldn’t rely on it for vacation shots. Stick to the DNG (RAW) format for the most control and detail. While Process Zero is convenient, it pales in comparison to Apple’s ProRAW format, which provides significantly more flexibility for those looking to capture and edit with the finest detail.

This experience has solidified for me that DNG (RAW) is the way to go for detail and post-processing flexibility. Process Zero may sound like a hassle-free option, but its inconsistency makes it unreliable. For crucial shots, nothing beats editing your DNG (RAW) files yourself.

But I may be titling at windmills here. Maybe I can heed the words of fstoppers writer Alex Coleman.

When it comes to interchangeable lens cameras, raw is a clear benefit over JPEG. In phones, however, the files have little additional latitude when saved as a raw file. Sure, you have less discretion over HDR and white balance by sticking with the default camera app, but are you really micromanaging those settings when shooting with a phone?

There is a Good Reason For Why Ricoh’s Theta X Now Shoots DNG RAWs https://petapixel.com/2024/09/20/there-is-a-good-reason-for-why-ricohs-theta-x-now-shoots-dng-raws/ #360degreecamera #ricohthetax #360°camera #Equipment #firmware #ricoh #News #dng #hdr

Lossy DNG isn’t so bad

Have you ever converted a RAW file to lossy DNG and noticed how much smaller it was? You can make the RAW file 80-90% smaller! I always thought of lossy DNG files as JPEG files saved at a compression level of 10 or 100%. In other words, with barely anything stripped, but it’s more interesting than that.

I discovered that a panorama I made in Lightroom was a lossy DNG. After I made it, I tried converting it to lossy DNG, and the new file was the same size as the old one. So, panoramas are lossy DNG. They used to be huge files, but, in Lightroom 13.0 that changed. Adobe started using Jpeg XL instead of Jpeg to store data in lossy DNG files. Even though the files are smaller, they are higher quality than older panoramas! It’s the same with HDR and Denoise. Remember when Denoise was introduced and the files it made were gigantic?

HDR images created by Lightroom are also now saved using the same lossy DNG format. An HDR image I created in 2017 on my 24MP Sony A7III is 77MB, but using Lightroom 13.3.1 that file is only 11.9MB. When I convert the image manually to lossy DNG with an embedded medium Jpeg and fastload data, the file reduces further to 8.1MB and looks practically the same at 100%.

I haven’t noticed any major problems fixing highlights or shadows in panoramas, so lossy DNGs are pretty good, but not without their own drawbacks, which I’ll get to later.

On the Adobe forums someone noticed this last year, and received a few interesting replies:

The compression method for derived DNGs has been changed from JPEG to JPEG-XL, which provides a smaller data footprint without loss of quality.

Creating a merged DNG such as a panorama is already a “lossy” process because the merged pixel data has been demosaiced, aligned, and blended from the original photos. Using JPEG XL compression makes a much smaller visual change.

Do not look at the words ‘lossy’ and ‘lossless’, look at your image and see if there is any visible effect of this new compression method. Recreate an older panorama and compare the old massive DNG with the new, much smaller DNG. Do you have any reason to be concerned?

Before you convert all your RAW files to lossy DNG, be aware that it will affect how Lightroom treats your file in ways you mightn’t think of. Years ago, I noticed that the Transform tool worked differently on lossy DNG files. It straightened walls slightly differently, not that it looked wrong, just different. You also can’t feed DNG files to Topaz Photo AI (Files->Plugins Extra->Process with Topaz Photo AI) or Lightroom Denoise, so use those before making your panorama or making the file a lossy DNG.

This is an example of a simple image that transforms differently when it was converted to a lossy DNG file. Lens correction has been applied to both images, and they are identical then. However, when “auto” transform is applied, the lossy DNG is modified differently. This bug has been there for years. If you want to compare yourself, here is the before image, and here’s the after image.

Greg Benz has published a post on the subject too and came up with the idea of exporting images to lossy DNG “to the same folder” and adding them back to the catalogue, making it easier to compare before and after images before you delete files. He points out some other problems I never noticed with lossy DNGs, such as haloing and colour tones, and other unspecified issues with older RAW images imported before 2012.

Is it worth converting your RAW files to lossy DNG? You’ll make savings of up to 90% and that’s very tempting. A 66MB RAW file may become a 9MB lossy DNG file. If you don’t like deleting, but you’re sure you’re not going to use an image, then it may be an option for you. On the other hand, use with caution on photos you want to edit and publish.

A comment on this video suggests loading the original photo and the lossy version into Photoshop as layers and use the “difference” blend more on the top layer. You’ll notice tiny changes between the images. Since I have deleted the original RAW file of the photo above, here’s one of the lighthouse at Ballycotton.

Here’s what the difference looks like in Photoshop.

There are obvious differences when you look at it like this, but I still think it’s worth considering. Today’s photo on my photoblog, The Rocks of Ballycotton, is a lossy DNG file for example.

And finally, one thing to consider is that third-party software support for lossy DNG files might not be what you expect. I haven’t tested any of the open-source software out there, so I’m not sure how good it is. A comment on that video I linked to above says RawTherapee handled them, and that was 6 years ago, so I’m sure the situation has improved since then.

While in the process of researching this, it has been so nice to find actual open, public, online forums and blogs talking about this, and not just on Reddit either. I bet there must be plenty of conversation about it hidden in Facebook groups too. Hidden from prying eyes.

Oh good
Bad news: something somewhere somehow has broken my janky Power Automate thing for converting raw photos to DNGs with the Adobe software.
Good news: there is an actual open source command line #DNG converter now. Maybe I don't need the janky thing soon.

@ashley @Thorsted Thought you'd both find this post interesting: https://blog.brixit.nl/megapixels-2-0-dng-exporting/ (Adobe's got a cross-platform library that can validate #DNG files?) #digipres

Really enjoying shooting with the #GRIIIx but it's a shame the AI denoise in Lightroom Classic doesn't support the #dng files from the #griii series. Hope a patch is coming soon.
