?Hello friends, I did a project shoot recently with my Canon EOS 1D. All the photos were shot in RAW CR2 file format. The photos were fine in the camera, but when I transferred them from the SanDisk Extreme Pro 32 GB memory card to my Windows PC, they showed up as corrupt or unreadable. Is there a way I can repair corrupted CR2 files? Please help.?
CR2 is a RAW file format for photos that Canon supports. CR2 files are uncompressed, so they are of high quality. But like other photo formats, CR2 files are not immune to corruption and can turn corrupt or inaccessible due to various reasons. The next section describes the reasons why CR2 files turn corrupt.
Common Reasons for CR2 File Corruption
- Improper insertion or removal of SD card from a camera, card reader, or computer
- Sudden system shutdown during CR2 file transfer
- A low battery in the Canon camera resulted in the improper saving of CR2 files
- The presence of bad sectors on the storage drive containing CR2 files
- Virus or malware in the computer damaging the CR2 files
Addressing the above, we have created a detailed list of the best and safest methods to repair CR2 file issues.
1. Set Photos as a default app for CR2 files
In case your CR2 files are not opening, set Photos as the default app for them. Go to Settings > Apps > Default Apps. Scroll down and click Choose default applications by file type link. Scroll down to find .cr2 CR2 File and click ?Choose a default? (if not set). Specify the Photos app.
2. Open CR2 files in a different photo-viewing software
When CR2 files don?t open in one photo viewing application, you must try a different one. For instance, if you are viewing your CR2 files in the Photos app, change the software to Adobe Photoshop, Lightroom, or Canon Raw Image Viewer.
3. Update the software that you are using to open CR2 files
If you can?t open your CR2 files in Adobe Photoshop, IrfanView, Lightroom, or other software, ensure that the photo-viewing software is updated. If not, update the software and then open the CR2 files in it.
4. Convert CR2 files to another file format
When CR2 files don?t open or throw an error, try converting them to another RAW format, such as ARW, DNG, or JPEG. There are many free RAW file converter tools available online that can help you convert your CR2 file to another format.
5. Reduce noise in CR2 images by using an image editor
In case your CR2 images are grainy, blurry, broken, or pixelated, use an image editor like Adobe Photoshop or Lightroom to resolve the issue. Although you may not be able to remove noise from CR2 images completely, the images can be edited to an acceptable form.
