Prefix file name underscore versus 8

I use Adobe color space for my 5D Mark 4 which uses a file name with an initial underscore. However I am finding that on some of my folders the majority of my files will be correctly labeled with an underscore but then a lesser number of them will randomly instead have an 8 starting off the name of the file. I contacted Canon technical support and they have never heard of this issue.

Re: Prefix file name underscore versus 8

Does the same issue occur on more than one memory card? Have the memory cards been formatted in the camera? Does the EXIF info for the affected images in fact show them being saved in the Adobe color space, or do you see any other strange changes in the EXIF data between the different file naming structures?

The underscore in the filename indicates you are using a different colorspace. i.e. AdobeRBG

 

Did you set a different colorspace that got saved in one of your Custom Settings (C1, C2, C3)

Thank you for your reply!!!

 

Yes - it has happened with 2 separate CF cards - the most recent with a 128GB card.

 

Yes - the cards were formatted in the camera.

 

IF by EXIF you mean Details under Properties, under those .jpgs correctly listed with an initial underscore, the Image Color Representations states "Uncalibrated" .................whereas the images that start with an initial 8 in the file name, the Image Color Representations state sRGB.

Re: Prefix file name underscore versus 8

Are you saying that there might be something wrong with this camera as this has happened on and off during at least the past year - as shown in pictures May 2018 also.  And if htere was something defective with the camera, will I be charged for it?  You will see there is no damage to the caera whatsoever.

Hello Zbadger, 

It's hard to say at this point, there very well could be.  We would need staff on hand at the FSC to evaluate your unit.  If you are within the initial one year period since purchase, we recommend sending a copy of the receipt so we can process the warranty.

Re: Prefix file name underscore versus 8

Are any of the misnamed files HDR captures?

If one of your Custom settings (C1, C2, C3) has sRGB colorspace saved in it this would explain it.

 

Also as metioned by Waddizzle any factory preset modes like HDR are likely to use the default sRGB colorspace.

Re: Prefix file name underscore versus 8

My HDR images are Adobe RGB images, but I just checked my first C1 setting and sure enough, a photo I took had an sRGB image taken.  However, I have not been using C1 when these occasional images with an 8 prefix have showed up.
