My Lenovo P32U monitor is set to Adobe RGB color space. Lately, I switched my camera color space settings to Adobe RGB. I previously was using SRGB color space in my Nikon cameras. Question about the NEF Codec – I performed a web search for “customizing NEF codec to use the embedded color space” and on top of the list is your blog on SRGB and Adobe RGB. I don’t remove them, though, because I don’t want to modify my master images. Once you’ve got them into Lightroom or Aperture, all they do is waste space. There’s no way to inhibit the inclusion of the embedded jpegs that I know of they’re used by the camera itself when displaying the image on the LCD, and by most image-viewer programs (e.g. For most people, it makes little sense to do both. The smaller file size of the JPGs makes that kind of very quick access possible, when every second counts. These days, the only reason to shoot raw+jpeg that I can think of is when you want the long-term quality of the raw files, but need immediate, quick access to the images (such as to pick a few from the sidelines, to send to the home office during a timeout). My objective is to make a long lasting master image archive/database from which to make copies and other images for different uses. Why is it there? Can the user access it? Get rid of it to reduce the file size? Add the metadata to it?

So it seems odd ,to say the least, that Nikon D3100 has the option to shoot RAW + Jpeg fine when the option Raw only= NEF file already has a full size embedded jpeg. I have bought Nikon D3100 but cant find a detailed explanation of the image files structures or tools to examine them. Thanks for NEF, Color Space Settings, and Embedded JPGs. Including an indication of their color space.

If you have Phil Harvey's most excellent ExifTool (nowĪvailable in a Windows stand-alone executable), you can easily extract these embedded images:Įxiftool -b -PreviewImage file.NEF > file-Preview.jpgĮxiftool -b -JpgFromRaw file.NEF > file-FromRaw.jpgĮxiftool -b -PreviewImage file.JPG > file-Preview.jpgĮxiftool -b -ThumbnailImage file.JPG > file-Thumb.jpgĪgain, be warned that none of these extracted images have any metadata, Metadata that the embedded “JPEG from raw” doesn't have, of Images 3 and 4 are identical if the camera is set to produce Largeīasic-quality size-priority JPEGs.
