Losing metadata

[gugs]

[FONT=Verdana, sans-serif]A question about metadata...

I just started to use Lightroom and I have a small issue, visible among others on flickr.

When I am using Nikon software to process my pics, I see all the relevant metadata like the lens used, the maximum aperture etc... in the processed pic, even after upload on flickr.
When I use Lightroom, most Nikon stuff, including the lens info for instance is gone. Only the basic parameters like shutter speed, aperture, picture size etc are still there.

Any idea on what to do not to lose anything. I am just a beginner with this...

[/FONT][FONT=Verdana, sans-serif]I am using Opanda exif viewer to check...

here is an example in flickr of a picture processed with Nikon Capture NX

[FONT=Verdana, sans-serif] here is the limited data I get after using Lightroom

the same is true if I use an exif viewer before uploading.

I just rechecked and it could be that Lightroom is storing the metadata in a non-Nikon format, because if I reopen the exported jpeg in lightroom I see the lens I used.[/FONT]

Anybody an idea ?

Thanks in advance for any useful info.

Guy, welcome to the forums.

Verify that, on export, the 'Minimize embedded metadata' checkbox is not checked. (Although, if you're seeing the data on re-import to LR, that setting is probably correct.)

Welcome to the forums Guy!
Do you have "Minimize Embedded Metadata" checked in the Export dialog box?...

 

[gugs]

in fact the minimize embedded metadata is not checked, I would say that I am losing half of the metadata (in standard tools, not in LR !), and those data are usually tagged "Nikon" data. If I check the minimize embedded metadata option, only the picture size is left, all the rest is gone (even used aperture, shutter speed etc...)

I think we're seeing a side effect of the way that LR is treating 'Maker's notes'.
LR stores metadata in 2 ways in exported files,

1) in the standard locations as defined by the JPG standard, combined with the applicable metadata standard, e.g., IPTC, Exif, etc. (generally, but arguably not completely)
2) in the XMP segment, which is defined as an 'open' standard by Adobe.

I'm speculating that the Nikon 'maker's notes' are being processed into the XMP metadata, by LR, but are not being inserted elsewhere for non-XMP aware applications.

Just guessing, don't have a Nikon to play or CNX to play with.
