I don't think that's true. Capture One introduced HDR merging in one of their recent releases [0].

It does raw in "raw" out. You get a DNG out which is demosaiced. I have not yet looked to see what it's doing under the hood, and how the result compares to EXR. (But in my experience, it seems to struggle with large exposure differences, even when on a tripod).

I mean, sure, producing another raw is one way to do it, but I wouldn't really call that an image format.

I have no idea why you wouldn’t call it an imagine format.

But either way that’s changing the goal posts. Here is a consumer software doing what that iPhone does.

If that’s not to your liking, there is other software which produces 32bit float tiff images, those will support an even higher dynamic without the pain of EXR.

You are all over this thread trying to prove that iPhones somehow have a unique setup in the industry that no other camera can match, and people keep telling you how wrong you are. DNG is 100% and image format, and can be “raw” or completely processed depending on the layers internally. Educate yourself before making such blanket statements.

I know what a DNG is. It's not a final delivery format; it's not compressed and I don't think eg gaming content pipelines are going to accept it for ingest either.

(Also, macOS won't display them in HDR, but will display EXR files in HDR. Some trivia for you.)

-> It's not a final delivery format

linear DNG?

-> it's not compressed

"Lossless and lossy compression (optional): DNG support optional lossless and (since version 1.4) also lossy compression.[36] The lossy compression losses are practically imperceptible in real world images"

-> I don't think eg gaming content pipelines

Why is this a goalpost even??? In what context? Photogrammetry? DNG works just fine.... Or the actual engine itself? found one in 30 seconds of searching: https://github.com/EQMG/Acid

-> macOS won't display them in HDR

Well, that seems like a macOS problem

This is ridiculous at this point.

After this comment I get where you’re coming from.

Do you consider the heic files from an iPhone hdr files rather than sdr, even though the extra brightness channel is stored as a separate channel rather than extending the range of rgb values?
