Image glitch: Split Images

[NLFord]

Im on a Mac OS 10.11.6 using Photo Mechanic 4.6.9 with Raw images from a Nikon D5.  I'm getting distorted images in Photo Mechanic, but when i open the image in photoshop, it's fine.  See screen shot. Please advise.

I expect that the JPEG preview in your RAW files is damaged in some way and the reason Adobe's software is unaffected is because they're ignoring the JPEG data and are rendering the RAW file instead.  Photo Mechanic shows the embedded JPEG preview and does not render the RAW file.

I suggest checking the integrity of your camera card.  It may be beginning to fail.

Actually, when it first started happening I suspected it was the card. But it happens on any card.  I am beginning to suspect it's something in the camera. I thought maybe photo mechanic and my old system (maybe the graphics card?) couldn't handle the large files anymore (i also use the same cards in a D3s) and it doesn't happen.)   It can't be cause the files are large, because it doesn't happen on a D850, which the files are twice as large as the D5. I should probably try downloading on my home computer to see if it happens.  Thank you for your response.

I am getting similar issues, only the files are genuinely corrupted, even when I open them in Photoshop. Not only are the files often split, but many are off colour too. I have suspected it has something to do with Photo Mechanic since it was only once I started using Photo Mechanic that I have encountered this problem. That may, of course, not be the reason, but the correlation is there.. And there are a lot of them that are like that. Please seen the screen grab attached.

What file type is the image?
Do you have the image still on the card?  If so, if you open the image off the card with Photoshop, is it similarly corrupted?

Hi Kirk,

These are images that were taken on an iPhone which uses a .heic file format. Ahead of archiving them in Photo Mechnic, however, I convert to .tiff. This has continued to happen and I now have many corrupt files. Sadly I do not keep the original .heic files so could not show you those. When I first enter them into Photo Mechanic, they are absolutely fine. It is only some time later that I notice that they have become corrupted. At time I have been able to recover from a backup, but that has not always been the case.
