Sorry if this isn't the right forum for this question...
I had to re-format my hard drive, and lost all programs on it. I have reinstalled most programs, but for some reason I can't "see" my NEF files when viewing in Windows Fax and Picture viewer or Photoshop File Open menu. When I select "thumbnail" mode for viewing the file, I get an icon only. I have downloaded the Windows RAW image viewer to no avail. Previous to having to wipe out my hard drive, I could see the NEF files. I must be having a brain fart/senior moment about downloading some software, a patch or codec? Without having to go to ViewNX2 (which works fine) what do I need to do so I can see these files. (An answer of "get a Mac" does not help at this time.)
I'm trying to view NEF files from a D70, D200 and D300. I have Windows XP SP3 installed.
So this is kinda weird. Here is what I discovered.
Ever since I upgraded the D300 camera firmware, I can no longer see Thumbnail images of NEF files. I can go back to my old NEF files, and see images both in the Windows File Viewer and in Photoshop File/Open using Thumbnail mode. However, ever since the firmware upgrade, I cannot see file images of my D300 NEF files in Windows or Photoshop.
So, I assumed that the camera firmware upgrade slightly tweaked the NEF format so that I can no longer see a Thumbnail image using the software listed above.
However, I also noticed that my newer NEF images taken with my D200 can no longer be viewed in Windows File Viewer or Photoshop File/Open dialogue window. I have not updated by D200 firmware in quite awhile.
I am using Windows XP SP 3, and I download my files by removing the CF card from the camera, placing it in a card reader, and then attacing the card reader to the computer via a USB port. I have been doing this successfully for over 4 years in the case of the D200, and over 2 years in the case of the D300. I am using the same card reader and same memory cards now as I have in the past. I get the same issue regardless of memory card used.
When I upgraded to a D7000 I could no longer see the images on Windows 7 until I got the relevant codec from Nikon. Have you download the codec for the D300 from Nikon? You might want to try this link http://nikonimglib.com/nefcodec/
