Is it possible to convert Adobe XMP metadata to something usable

[charafocus]

Hi all,

This is a beginner question, and I do apologise if it's the right place for this.
I have a JPEG image that was edited with Adobe Lightroom, and doing so, a new entry is showing under the XMP data, called Exposure 2012: +5.00

Is there any way to extract and convert that value to something exiftool can understand and use it to apply that change to the original JPEG?

Thank you very much

ExifTool doesn't modify the image, so you would need some other utility for that.  But you could use ExifTool to extract this value and pass it to the other utility if it has a command-line interface. 

However, I think it would be easier to just do an auto-exposure adjustment on the image -- most image editing utilities have this feature.
