Exporting to RAW/DNG with color corrections?
Hello,
I like to export my pics to DNG-format with color corrections.
I read that this is not working in version 5.0 (13 years ago):
".... All changes made to the image will be discarded when creating the DNG file."
Ok, is this also in the current version the status of this issue?
THX a lot.

Hi Wilfried,
I could find the information on the Capture One site (user manual) for the version 14:
When exporting RAW files as variants using the DNG file format option, the settings files (e.g., any image adjustments made) and metadata such as descriptions, keywords, ratings, and color tags are not retained. You can, however, archive or share your RAW files complete with all adjustments and metadata intact by packing them together as EIP files instead.

See this guidance on the Capture One website.
https://support.captureone.com/hc/en-us/articles/360002629937-Exporting-to-DNG
When exporting RAW files as variants using the DNG file format option, the settings files (e.g., any image adjustments made) and metadata such as descriptions, keywords, ratings, and color tags are not retained.
DNG is effectively just another raw format.
Why do you like to export as DNG? What purpose are you trying to achieve? I wonder whether there is another way of doing what you need.

Hello to all,
thank you for confirmation of my suspicions ....
My idea was, to "feed" a sequence of raw-files (ready-edited) into the "LRTimelapse"-software.
This software uses a "all-raw-file-based workflow" , mhm ....
But I will now use a software for timelapse, with which I can use my beautiful finished jpeg files from C1 (e.g. "GlueMotion", ... ) .
Best Regards, Wilfried

What is the difference between a DNG and EIP file?

> Jill Kuchar: What is the difference between a DNG and EIP file?
EIP is a zip file archive containing multiple files, the original image file and files with C1's metadata/settings/processing instructions. Create an EIP file in Capture One, open it in your favorite zip tool and see for yourself. Depending on your zip tool you may have to change the filename extension from .EIP to .ZIP.
A DNG is an image file and can be packed in an EIP file along with files holding C1's metadata/settings/processing instructions for that image. If a raw file is an image file where the main image block is raw sensor data, some DNGs are not raw files.

A DNG file is a particular format of RAW file developed by Adobe. Some cameras use DNG as their raw format. The name DNG derives from "digital negative".
An EIP file is a type of file specific to Capture One. EIP stands for Enhanced Image Package. In Capture One your edits are stored in .cos files (and sometimes some other files depending on what you have done to the image, for instance .comask files if you have done any masking) and these are stored in subfolders of the image folder (sessions) or inside the Capture One catalog database (catalogs). The purpose of an EIP is to bundle up the image file with its .cos and other edit files into a package that can then be sent to another Capture One user. A typical use would be to send edits to and from a retoucher, but you could also use them to transfer images from one computer to another. Once the EIP file has been received by someone else, they can get Capture One to unpack it and they end up with the raw file plus the .cos and other edit files, the same as you had before you packaged it.
Software other than Capture One can't make use of EIP files. Capture One sessions can pack images as EIPs. Catalogs can't but they can still export images as EIPs. (This is because of the different ways that sessions and catalogs store edit information.)

> Ian Wilson: A DNG file is a particular format of RAW file...
Like I said, it depends on your definition of a raw file. If a raw file is a file where the main image block is raw sensor data, then there are quite a few DNG files around that are not raw files. They are commonly referred to as linearized, the main image block is RGB data. Adobe defined the DNG format, but I am not sure they have the power to define what a raw image file is or isn't. Take your pick.
As for EIP, you can follow my description and investigate EIP content yourself.

Yes, I know what's inside an EIP file, thanks. I was trying to describe the use of it.

I'd be surprised if you didn't :-)
Just a short followup on the DNG raw thing, I managed to dig up a 10+ year old interview Nat Coalson (photographyessentials) did with Eric Chan (Adobe). The title is "My Adobe DNG chat with Eric Chan" in case you want to search for it. To avoid having this post blocked while waiting 3-4 days for approval, I do not include a link here. It may appear to be a long read for some, so I will just cite a small part relevant to the question about absolutely all DNGs being raw files (or not). Here goes:
"NC: Thanks. So with all this in mind, is it still accurate to say that the image data in _all_ DNG files is _raw_ data?
EC: No, not necessarily. The reason is that the DNG file format can also store non-raw data. For example, you can feed a JPEG to the DNG Converter and have it spit out a DNG. However, that DNG isn’t raw, of course (you can’t take a rendered file like a JPEG and go “backwards” to make it raw again … it would be as miraculous as uncooking a steak!)."0 -
Thanks, I'll have a look at that.
