Allow the upload of Canon CR3 raws to the forum


sometimes it can be handy to upload RAWs to the forum.

Most RAW files are supported, such as Nikon NEF, Sony ARW and Canon CR2 but I’m unable to upload Canon CR3.

Is it possible to allow CR3 too?

Hmmm. have you tried zipping them to disguise the extension?

That’s a question only @DxO_Support-Team can answer. Whether or not they will answer I have no idea but we can all live in hope.

Meanwhile Joanna’s suggestion is a practical workaround.

Didn’t think of that…

Sometimes the solution can be so easy, if you think of it :smiley:

Its not reasonable or realistic for this forum to host an unlimited number of RAW uploads. Especially larger ones. Someone has to pay for the storage. Use a file sharing app, DropBox, GoogleDrive, Box etc and post a link. Its just not realistic to do so, and I’m not sure if Discourse even supports it.

Correct but that’s not what’s being requested by the OP. They simply want to be able to upload .CR3 format files, which will be no larger than already permitted .NEF files.

That’s a cr2 :wink:

The newer cr3 isn’t supported

after cleaning my glasses and paying more attention to details, I saw what you did :joy:

Then don’t allow uploading at all. Now Nikon, Sony and Canon CR2 files are allowed. Zip is allowed, even MS Word .doc is allowed but the already a couple of years available CR3 isn’t.

Many forums cap uploads at 5MB. But its not my forum and I’m not footing the bill. I understand there is significant hardship having to spend 2 minutes and click a mouse 3 more times. Many forums, except file sharing websites don’t support anything except .jpg, .png. anyway. Guess we will see if Discourse supports it. If they decide to add it, great.

Ah good, I was just about to come round with a bucket of cleaning solution :rofl:

It’s just a case of renaming the final extension and @platypus simply added another, acceptable, extension instead of zipping it. Now, what were we saying about computers being intelligent? :laughing:

They are not “intelligent” but only “artificially” intelligent :grinning:

I never said that. I guess you missed the post where I tried to upload a CR3 file to the forum and found out I can’t. You’re solution is exactly what I did: I uploaded it to my own cloud storage and shared a public link.

But that is beyond the point of this forum management suggestion. If you support all major RAW files including CR2, NEF, ARW and DNG plus various other, potentially very big, file extensions such as zip you can also support CR3.

It has nothing to do with Discourse supporting it. All forum software I used you can simply set a list of allowed extensions. The forum software doesn’t have to render it, just offer it as a download as it does with the other RAW extensions as well.

What other forums support isn’t relevant.
