Just to clarify, display of EXIF metadata is checked in my Image Carousel settings under Media Settings.
After uploading an image containing EXIF metadata and inserting it via the Gallery shortcode, the metadata no longer displays in the Image Carousel as it did previously. The only way now to see the EXIF data is to download the original uploaded image.
The loss of the EXIF metadata seems to occur when WordPress.com resizes the image for display in the Post or Page. The Image Carousel also appears to display a resized image (on my monitor, it's 1000 pixels wide).
The blog I need help with is gammagirl.wordpress.com.
