I was reviewing Raw photos shot earlier in the year with my Nikon 7200 and noticed there wasn’t any info in the file. The photo was in color but lacking White balance, exposure info etc. I then opened it in PS21 and a message appeared that it did not have a color profile and did I want to add one which I did. This got me looking at more photos and I noticed several more with no Profile. However it wasn’t consistent. Some had it some didn’t in the same folder. Anyone else ever had the same experience? Could it be a Card Problem? Both Camera and Cards have been replaced since then so I can’t replicate the conditions?

For RAW files, the colorspace is added (defined) by the digital editor. This colorspace is then used to create and define the resulting display format file that is converted (created) from editing the RAW file, display format being JPEG, TIFF, PNG, etc. The RAW files from your D7200 will have the NEF extension.

To your question of what happened, you'd have to tell us more about what happened. These files seem to have some age in that they're not direct from the card. What editor / editing has happened before? Are you saying the EXIF data has been stripped, like the shooting date, camera and lens info, aperture, shutterspeed and similar exposure data? Is the data all gone? Are the EXIF parameters consistently missing, like they're all missing the same values?

Conceptually, RAW files have two components: the read-only image data and text-format 'header' data that describes the image attributes that is the EXIF data for the examples above. It's possible the EXIF portion of the files has been corrupted or edited or erased by another software, probably by accident or an unintended result. Typically, saving the original RAW, given the files are mostly read-only, is all that is needed for a back-up strategy. Do you consider these files the original from the camera or has something else happened in their history?

Is the issue possibly the PSE21 organizer? I don't have this software, but is the possible issue that some have been imported differently into PSE21 and / or edited in the past and others not, such that PSE21 has different stored attributes that you're now discovering as you open individual files?

Raw files don't have a colorspace out of the camera. When they are in a program like photoshop elements there is a working colorspace while they are in the initial camera raw part, which in photoshop is basically prophoto. When you open that file from the camera raw part to work on in Elements it is converted to either a tiff or a psd and elements will apply a colorspace according to the Elements color management settings. But when you save or export that file for example as a jpeg it can imbed the profile or not.

So how did you export or save them? I know Photoshop CC has a clickbox for 'imbed profile' and another for 'convert to srgb' when you use export as. The file you are reopening is of what file type?

Thanks for your response. I use the Nikon Program View NXi to transfer the photos from the Card to my Desktop PC. The Program creates a Folder for the images. I then review the images and rate them. The Program also lets you view all of the Exif data and also make changes to Exposure, White Balance and some other basic adjustments. In viewing photos (I can see it in color on my Monitor) I noticed some -not all- photos in the Folder were missing the Exif data and I could not make any adjustments to them. I then Opened one of these photos in PS21 to see what would happen and that is when a pop up message said the photo was missing a color profile and did I want to add one-RGB or Srgb. Once I selected a Profile the image opened and I could edit it.
The mystery is why the Exif data was missing from only a few of the photos in the Folder.

If your not having the problem after replacing your memory cards, it probably was a corrupted card. I believe it is better to format your memory cards in camera. Do you format your cards in camera? Also if you have more than 1 camera you use the cards in, the card should be formatted in the camera it is being used in.

That is troubling. Are you shooting jpeg or raw?

I’m shooting Raw. I only have one camera and the Card was formatted in the Camera

I only have one Camera and I always format the Card in the Camera. I’m going to chalk it up to a defective Card
