    Default Viewing Nikon D300 RAW NEF files in IrfanView

    Hi all - IrfanView is opening all of my portrait orientation Nikon D300 RAW NEF files in landscape format. I have the auto-rotate image according to exif info option checked and have no issues with rotation not working properly when viewing RAW NEF files taken with my Nikon D70 - any clues? (additionally the D300 thumbnails appear in the wrong orientation in Windows XP explorer whereas the D70 thumbnails are OK, however in IrfanView thumbnails view the D300 thumbnails are rotated OK) Thanks for your help.

    Hi expeditionist,

    Maybe the setting to insert orientation info is off in your D300?

    Open the EXIF information for one of the images (type I,E or use the menu) and look at the orientation tag. If it says Top Left then it will not be rotated by the Auto-rotate feature.

    Be very, very careful if you want to avoid the orientation tag being reset to this value by IrfanView 4.10.
    First if you Save the image you must uncheck the Reset EXIF orientation in the JPEG save options.
    Second do not use JPEG lossless rotations at present. They appear to reset this flag even when the above Reset orientation option is unchecked. I don't know if this is a bug or a well intentioned feature gone wrong.

    Default D300 EXIF info not read by IrfanView???

    Hi again - thanks for your replies:

    Here's the EXIF info from one of the portrait files that is correctly orientated in thumbnails view but it opens incorrecty in landscape view when it's opened with IrfanView:

    The orientation flags for these files say 'right top'. Not sure whatthat means?

    I don't think that the comments about saving JPEGs come into effect here because I'm trying to open new RAW NEF files which haven't been edited yet.

    I had some related feedback from Nikon who tell me that Windows XP Explorer can't read the EXIF data for D300 NEF files because it's such a new camera and XP doesn't know how to read the D300 EXIF data - the EXIF data isn't the same as for the D70.

    However, these files do open correctly orientated for editing in Capture NX and Photoshop CS2 (once converted to DNG).

    What do you think? Thanks again.

    Hi expeditionist,

    I also read "Orientation - Right top" in the EXIF data from portrait pictures. Though IrfanView displays them rotated correctly. They come from a D200. But they are JPEGs. I didn't try with NEF files.

    Note that the "Auto-rotate image according to EXIF info" option is for JPEG files.

    Hi again

    Yes, the "Auto-rotate image according to EXIF info" option is on.

    I suspect that IrfanView doesn't support the D300 EXIF info yet, but would like someone to confirm that.

    Interested, I checked the EXIF info for my D70 portrait NEFs and it's different to both the D300 and the D200 - the width and length appear relevant with the D70? See here:
