R5 Mk II - Multiple Exposure saved as RAW files via Firmware update.

[C-Cella]

I have yesterday bought a Canon Eos R5 Mark II.

This high end premium camera does NOT allow to save "Multiple Exposure" as RAW files like its predecessors (e.g Eos 5D series, and even the R5 Mark I)

The "feature request" I make is to add via a Firmware update the option to save Multiple Exposures as RAW files not only for the R5 Mark II but also for other Canon cameras.

I'm also very upset that the manufacturer removed this feature. They could have added a menu option to choose the format in which to save. I like RAW. I would prefer to save in this format. JPEG doesn't have any value for me, so why does the manufacturer choose the format for me? I don't need JPEG at all. I don't like the multi-exposure feature at home on my computer; I like it in the fields, outdoors, and I want to have this feature and the ability to save in RAW right outside. IN A SINGLE FILE, NOT TWO!!!! PLEASE! EMIT A NEW FIRMWARE WHERE THIS ISSUE WILL BE CORRECTED!

PLEASE !!!!!!

Canon got it wrong for years.  If the camera saves a RAW file, then what data should it write to the EXIF metadata?

You can create a double exposure using any image on the memory card, even ones captured using a different lens and exposure settings compared to the photo you captured today to create the double exposure.

What exposure, lens, WB, IS and Flash status, etc, should it write to the EXIF metadata?

I'm taking photos, not creating EXIFs. If you need a camera for EXIFs, that's your problem. Don't decide for everyone. Other people might be taking photos with cameras.

Let me put it this way.  The camera MUST write out metadata. It should not write invalid data, because that would mean that the camera is not conforming to its own specs.

https://en.wikipedia.org/wiki/Exif 

The camera can’t leave undefined fields empty because a RAW file editor wouldn’t be able to do anything with it. The editor needs an initial set of parameters. 

 So, I ask again. What data should the camera write to the EXIF?

I don’t think anyone can answer that question.  Like I pointed out earlier, by combining imaged the camera is creating a digital print, which means a JPG file.

Read the earlier comments about EXIF

Canon could write in their proprietary RAW the relevant metadata for each single shot in the Multiple Exposure.

In the end it would be the role of the RAW editor to choose which to use BUT as of today as a convience only the last shot metadata is saved for the combined exposure.

Calming that metadata correctness is a good reason to not allow multiple exposure it is hardly sustainable.

JPEGs also have metadata (creation date, shutter speed, aperture) and yet we can create multiple exposure in that format.

Multiple Exposure for RAWs was the norm for years and years in Canon Cameras, there is even a Canon offcial blog about how great it is.

I has been removed from the latest cameras and it is our loss as photographers that relied on it for our work for all those years.

Canon has broken continuity by removing the ability to do it for RAWs but can easily reinstate it... it's purely a software thing and they have the know how.

JPG files do contain mtetadata, but there’s no requirement for all the fields to contain data.

As far as what Canon DSLRs did in the past goes, those cameras got it wrong.  Their metadata would contain empty fields.  For example, the WB field is undefined.  You cannot adjust it!

Again, a composite image is technically a digital print, not RAW data. I am not aware of any photo editing software that creates composite images and saves them as RAW data files. Do you?

“ Canon could write in their proprietary RAW the relevant metadata for each single shot in the Multiple Exposure. “

Like I pointed out previously, doing so would mean that the camera is not conforming to its specifications.

What you say Waddizzle is false at all levels.

Canon can write whatever they want in their own property files.

They could add more metadata indicating the settings of each shot in the combined multiple exposure done by the camera.

Panasonic cameras allow to create multiple exposures in RAW format and no institution, nobody has said that that is incorrect or is violating rules or not in line with specifications or IPTC rules rules NOR panasonic was aksed the to stop doing it.

You claims are false, you fabricated the to support your argument.

As long as the RAW contains the necessary metadata (which would be the case).it will be perfectly fine for Canon to save ONCE AGAIN  RAW multiple exposures.

So don't like the idea, you ahve this right, but your arguments agaist it are non factual.

I suggest that you make use of the product feedback process.  You have some great ideas. 

As for my claims being false goes, try opening up one of the composite RAW files from your older camera.  Can you adjust the WB? Or, is it fixed like a JPG? It’s fixed.

 I can change WB of my MultipleExposure Canon files taken with EOS 5D mrk.3 and 5DsR

. R5 allowed to.do MultiExposure RAW and I sure the WB is editable
