This happens to me every now and then: I get weird lines and colours when I import a RAW file. I'm using Lightroom with Canon raw files on an iMac.
I can see the image in my Finder (would be the embedded JPG thumbnail preview) but when importing it to Lightroom it goes very weird.
Here's a screen shot:
|IMAGE IS A REDIRECT OR MISSING!|
HTTP response: 404 | MIME changed to 'text/html' | Byte size: ZERO
Any ideas on how to fix this?
