    Images imported... some ruined with blank white and color banding

    soloalpinist Community Member

      I'm using Lightroom 4... i've been importing my RAW images from my external harddrive. Some show up in the catalog as ruined with a blank white section and color bands.  I've checked the actual image on the external hard drive and it is fine. I've deleted the ruined files from the LR catalog, then re-imported those problem ones... still come in as white with banding.  I've even tried deleting them from the catalog, then from the harddrive... then back onto the HD from the camera, then back into lightroom. Some look ok until I look at then in loupe view... and the same problem happens.  Meanwhile the images on the HD and on the camera's CF card are fine.  Suggestions???

          Can you show us an example via screen capture?

          I've checked the actual image on the external hard drive and it is fine.

          Usually what people see when they do this is the JPG preview that is embedded in the RAW, and if that is fine, it tells you nothing about whether or not the RAW is fine. How did you check to see things are fine?

           

          Usually, when people have problems such as this, it winds up being a hardware problem somewhere in the chain of events (could be camera card is bad, card reader is bad, hard drive is bad)

            OK.... I just pulled up one of the bad images in photoshop... it came up in the camera raw window initially as bad... and the yellow exclamation mark was at the top. once it full open in the raw window it was back to normal.  BUT... I tried this on a second image and it stays "bad". Attached is a capture of the bad image Capture.JPG

              From the screenshot you’ve posted, it would appear that the images are corrupted in one way or another, with non-image data being interpreted as image data which looks odd. 

               

              The initial view you see with other software that you’re using the judge they are fine is probably just showing you the embedded JPG preview of the image which is at the beginning of the file.  The raw data follows that and it appears that some of the raw data is corrupted. 

               

              You can upload an example image to www.dropbox.com and post a public link if you’d like others to check things for themselves.

               

              The important thing is why the images are corrupted…somewhere between the camera sensor and LR, but there are memory cards, and usb cables and usb-drivers and hard-disks which might have issues.

                Thanks... that makes sense... but the one thing I can't understand is when i opened one of the corrupted images in photoshop (from the hard drive) it showed the corrupted image in the raw window initially... then it showed the image as fine and uncorrupted after it fully loaded.  I saved copies as a jpeg and a tiff... they are fine when I open them.  

                So... if there is corrupting going one somewhere... why in the end would an image "clear up" in the camera raw window in photoshop.. and another won't?

                  The corruption could be anywhere in the raw file, including in the preview, there is just much more chance that the corruption is occurring in the raw data because that is a majority of the file.

                   

                  You might upload the one, initially corrupted then eventually ok-looking image, to let some of the rest of us examine, as long as it’s a publically viewable subject.
