The Image Info page displays an assortment of image attributes that might be relevant to noise reduction. This makes it easier to verify key properties like the ISO sensitivity without having to leave the plug-in.
Most of the attributes are extracted from EXIF data, if it is available. The Exposure Correction field is currently extracted only from the XMP data that is recorded by Adobe Capture Raw.
The Quality field is set based on the file extension of the image. If the file has a ".jpg" or ".jpeg" extension, the Quality is set to "Fine JPEG". For all other file types, the Quality is set to "Tiff/RAW". If you shoot both RAW and JPEG images, you can create two sets of profiles, and the automatic profile loader can use the Quality field to select the appropriate set of profiles.
EXIF and XMP data might not be available for all images or in all hosts.
