I recently went to a photo trip and downloaded my files using Nikon Transfer and an external HDD in a laptop using Windows 7 Pro. Used 3 cameras. Nikon D700, D3x and D 800. I would transfer every night creating a different folder for every card. When trying to open some NEF pictures (I shoot raw, 12 bit, Lossless compressed) in Photoshop CS5, I got a message saying that the camera model was not supported by installed version of camera raw. ( I have the latests updates for camera raw for LR and PS). This happened on some folders downloaded with the D800, and none with any other camera. Some of the files were opened by PS, and showed at the top of the files a message saying that those were D800 images. I tried Lightroom 4 with no results. Those pictures seemd to have some bug in their metadata. When I saw the pictures in VIEW NX2 I had no problem. Also they opened well in Capture NX2. I shoot samples of all the memory cards I used with the D800 and they all open with PS and LR. I label my cards with the name of the camera so there are no accidental switches. WOrkflow is Format card, shoot for a day, download with Nikon Tranfer and reformat the card at night for the next day. I did a batch processing with Capture NX2 and transferred the "bad" pictures into tiff, and had no problem doing that. Those now tiff files, were able to be seen in LR and opened in PS for processing.
In summary, shooting D800 with raw images, PS and LR did not recognized some files ( all the pictures actually that were taken that day with that camera) yet in another days pictures originating from the same camera opened without problems in PS and LR. Also those ppictures in the "bad" batch still had no problem with Nikon View nx2 and Capture NX2. I suspect the metadata, Sometimes I get an error from a batch transfer using Nikon Transfer (I also have the latest version). Something that some metadata could not be found etc. What can go on to cause such a confusing pattern? Appreciate any help. Reserchead extensively the net but no clear reasons why this happens and how to prevent it.'Thanks
