Bridge is corrupting my RAW files (all SD cards)

Since a few months I started having some corruption issues with my RAW files. In the begining the issue  seemed appear randomly. When viewing in Bridge the photos in my SD, a few of them would look funcky and the problem would persist when opening them in Camera RAW. When trying to open those files in my computer (macBook Pro M1), the files would keep looking funcky. So I had to delete them and I started thinking that there was soemthing wrong with my camera or SD card. After trying it with other SD cards and even buying a new one, the problem persited: Some of the images would look funcky. I started fearing that my camera was damaged (canon 6D Mark II, firmware: 1.1.1). Nevertheless, after spending several hours doing multiple tests, I am confident to say that trying to view my RAW files in Bridge before transfering them to my computer is corrupting them. However, it does not seem to systematically corrupt every file, but some of them. The onlt way to avoid them being corrupted is to transfer them thorugh the Finder before opening Bridge and view them.

 

1) Insert SD card with newly taken photos in RAW file

2) Copy all RAW files in a local folder

3) Open one by one to check that they are Ok

-----> The files seem to be Ok (Apple Preview)

4) Open Bridge to view the photos in the SD card

-----> The files show to be corrupted (Brdige / PS)

5) Naviagte to the new folder where the RAW files were copied

------> The files seem to be OK (Brdige / PS)

6) Copy RAW files from SD card to a second local folder

------> The files show to be corrupted (Brdige / PS / Apple)

Bridge does not change files. However, you should never work directly on the SD card. ALWAYS copy files off the card first.

That's what I thought as well. I thought that Bridge does nto do anything to the RAW files. That is why my first intuition was to blame it on the SD card or the camera. However, as I just showed in the images that I described, in my case I have been able to replicate the problem every time I follow the steps I mentioned.

 

If it was true that Bridge is not doing anything to the files, then viewing the RAW files in my SD cards in Bridge should not result in their corruption. However, as demostrated in my case, it turns out that viewing RAW files in Bridge does do something to them. In my case, they are getting corrupted when I view them directly form the SD card.

Since this isn't possible, something else is going on.

Hi Santinemike,

 

What Lumigraphics is saying is completely true. "Looking" at a raw image, by itself" cannot change or alter a raw image (or any image for that matter). It's like looking at a picture on the wall and having that image be distorted by looking at it. (Any references to someone's glaze causing milk to curdle is not a valid point here! :D)

 

HOWEVER, the nature of the image's alteration does make me wonder about something else: can you please go into your ACR's Preferences and turn off your Graphic Processor?

First go to ACR's prefs

Then go to Performance and turn off the Graphic Processor.

Why this should happen and make a difference since you can properly see the images in your first screenshot I do not have a clue but I'm trying to come up with a reason for seeing what you are obviously seeing. 

 

To quote Sherlock Holmes from "A Scandal in Bohemia": "It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts."

 

My data says that this MIGHT have a greater chance to cause the issue than your suggestion. Let's see where this goes.

Hello gary_sc,

 

Thank you for your message and your interest in the probelm I am experiencing with Bridge. I followed the steps that you mentioned and restarted Bridge but the images that looked fuzzy still look fuzzy. Switching off the Graphics Processor made no difference. I turned it off, close Bridge, took some random photos with my camera and followed the steps I mentioned above. The result: Some of the images still get corrupted. The images that I imported through the finder BEFORE viewing them in Bridge look fine accross all software (Apple Preview, Bridge, PS, Topaz Labs Apps etc.), the images that were imported through the finder AFTER viewing them in Bridge look fuzzy accross all the mentioned software.

Obviously, Bridge is not systematically messing the RAW files of all people using it. I used it myself and had not problems for years. I have only been having trouble since a few months ago. And now that I am thinking aobut it, the issue more or less started when I got a new Macbook Pro M1.Maybe the new M1 architecture has something to do with this problem. I do not think all MacBook Pro M1 users are experiencing the same issue as me, but at least in my case I do believe Bridge is not merely "viewing painting on the wall".

 

As Bridge does create preview images of RAW files to speed up the process of viewing them as thumbnails, it is safe to assume that at least Bridge is opening the package in which painintgs arrive for printing a sticker of the paining and pasting it on the box. Something is happenign during that process that is damaging my files ONLY when they are found by Bridge as being delivered through an SD.

 

Best,

Miguel

Hi Miguel,

 

Quick question: are you doing anything in Bridge on the images while the images are still on the camera card?

 

Thanks,

Hello Gary,

 

I am not doing anything to the photos. I only open bridge, navigate to the folder my camera saves images in the SD and wait a for a few seconds till Bridge parse preview of them. Before the previews are processed, the images look fine (but with low quality). Once the previews are processed the images (and their previews) start looking fuzzy.

 

After testing several things, I think I was able to the detect that problem arises when the SD card is connected thorugh a HUB to one of the USB-C ports of the computer. When I put the card directly in the SD card slot integrated in the computer the problem doesn't seem to show up. I only did a few tests using the SD card slot. I will do some more.

 

As an interim conclusion, something weird is happening when Bridge reads and opens RAW files through my port hub, which is corrupting the files. However, this problem does not seem to happen when the images are read and opened by Apple Preview or other software.

 

Best,

Miguel

Miguel,

 

Hi Miguel,

 

I think we're getting close. HOWEVER, one of the biggest causes of issues that I've seen occurs when people try and do things to their images while the images are on the card. Why this happens, I'm not at all sure of but it's something that is often seen here in these forums. 

 

From a philosophical point of view, the people who open up their images on the card in Photoshop and make permanent changes to the image on the card WITH NO BACKUP, always stagers my brain, but that's another story. 

 

Anyhow, please try this: take a new batch of non-important images, open up Photo Downloader, and bring those onto your hard drive. And, for an experiment, please do this twice, once via your card reader, and once through the SD port on your computer. When you do this, do not look at your images on the card via Bridge or any other application. Just simply download the images. Now open the folder of images in Bridge — do any of them show any issues?

 

Oh, that makes me wonder, if you have any cards with the bad images, download those to your computer, again, do not look at them with any application, just download them. Do any of these show the issue?

 

One last comment/warning: One "feature" in Photo Downloader is that you can erase the card after downloading the images. DO NOT DO THIS!!!! It's a tragedy that Adobe has this there. Just like you cannot take a flash drive that was reformatted on a Mac and use it on a PC, there's no telling how any formatting done on a computer will be understood by any given camera. I do not know if you do this, or even think about doing this, do not do this.

 

Good luck, let me know how it works out.

You HAVE TO copy the files off the memory card to your hard drive. Period. End of story. Do not try to work with them on the card itself.

And no, Bridge is NOT corrupting your files. However, the card itself can become corrupted (the file structure) and you can lose data that way.

@LumigraphicsI did not even copied the files to my computer hard drive and they got damaged just by navigating to the folder where they were saved in my SD. Period.

 

I never worked on them in my SD card. I only wanted to see which files I wanted to copy to my computer Hard Drive. Period.

 

Viewing my files in othe rprogrames do not damges them. Bridge is corrupting my files. Period.

Bridge cannot corrupt your files. Period.

When you open a file (AFTER putting on your hard drive) in Camera RAW, how does it look?
