Importing a Raw file of a multiple exposure image done in camera into Affinity 2

[Geoff2250]

Please see attached PNGs - the final image is a multiple exposure of 5 images. I have also opened the file in Affinity 1, with the same result. The jpeg opens as it should look.

Hi @Geoff2250,

Welcome to the Affinity Forums & sorry to see you're having trouble!

How are you merging these multiple exposures and saving in the .CR3 format please?

I'd like to request a copy of this image in order to investigate further - can you please upload a copy of this .CR3 file here for me? If you'd like a private upload link for this file, please don't hesitate to let me know

According to its documentation, the Canon EOS R6 can natively create multiple-exposure RAW files.

That's nothing new with the EOS R models. My old, Canon 70D has that feature also.

I thought I'd replied to this thread already but it seems I put my comment in the wrong place. An added delay was because I had had to retrieve the e-mails from Spam.

The camera is an R6. Did you mean you wanted me to send the CR3 file itself ?

I might be able to as it's about a 20mb file,  but anything bigger and I don't think my internet could cope. As this was my very first attempt at processing this (and one of only a few tries at this type of photography) I didn't know if this was a "one off", but since my first attempt last week I thought I would try and process another and have had a similar reaction but this time purple was affected as well as red.

If you want me to send the comparisons for this one please let me know.

No problem at all Geoff, thanks for letting me know!

A copy of the .CR3 file which shows this issue would be best please, as I have tried to find a sample online for testing purposes but have thus far been unable.

You should be able to upload a copy of this CR3 directly to your reply here, but if you're having any trouble with this please let me know and I can provide an external Dropbox link for upload instead

I'm having exactly the same issue with a double exposure captured on the canon rp.

I'm sorry to hear this @joco - as above I'd like to request a copy of your .CR3 file for further testing here & so I can report this to our developers.

Are you able to attach a sample .CR3 file here which shows this issue please?

[joco]

@Dan C here's one

Many thanks for providing that for me! I can confirm I have been able to replicate this issue and will be logging this with our development team now.

I understand this thread is a bug report for Windows, but any Affinity users on macOS can change their RAW engine (Affinity Photo 2 > Preferences > Assistant > Develop Assistant > RAW Engine) to Apple Core and the RAW file will then load as expected.

I hope this helps

In further testing, it appears though this issue is already resolved in the latest beta version 2.1.0.1769 -

You can find out how to sign up for the latest beta here if you wish - 

I hope this helps

@Dan C brilliant, thank you
