Image data (XMP info I think it is called) not carrying over to LR 1.4?

[PrimaPhoto]

Good day,
This has been bothering me for a VERY long time.
I have done many tests but can't seem to find the solution, so now I present this question to all the LR guru's.

When I import my RAW images (taken with a Canon 2'D) in LR 1.4 the thumbnails all appear as they did when previewed in the camera but when I look at them in LR 1.4 they seem to revert to a different appearance - it is like the data associated with the image is lost?

This is very apparent when I import my infrared images (a Canon Rebel Xti, modified by removing the interior glass IR blocking filter and replacing it with a R72 filter) - the modification, I know has no affect because I see this when I import normal color images shot with my 2'D.

I remember seeing something about "preserve xmp info" or am I just confused from when I used to use Bridge?

Thanks.

Hi Mark! Welcome to the forums.

Very often the thumbnails are getting pulled from the embedded jpeg created by your camera. This has certain settings baked in and so the thumbnail looks like it did on the back of the camera. BUT, when you look at the RAW file none of those settings are there.

LR2 allows you to install camera profiles which will apply some of those standard settings to your RAW files making them look pretty close to the back of the camera. You can read about them at labs.adobe.com.

Mark, it's possible you have the cart before the horse. I think that you're talking about the most frequently asked FAQ concerning LR: read here.

If that doesn't address what you're asking about, ask us/tell us some more.

Excellent write-up Brad! Thanks!

Thanks Brad for the link to the document.
So if I got this straight when shooting in RAW mode it doesn't really matter what your camera is set to - you still end up with all the data the sensor captured.

Yes. And often, also an embedded jpeg preview/thumbnail file, which I believe does reflect the camera settings, but you'd have to verify that for camera/model. There are some subtleties involving reverse engineering of the mfgr's proprietary embedded data, about which I don't feel qualified to comment.

It really is raw data. That's why so much of the conversation you see is about camera profiles and develop presets. How to get from 'raw' RAW to polished output in the fewest number of steps.
