Exif is great but here is your obligatory reminder that if you are publishing images you should strip out some of the identifying information that cameras and image editing software likes to embed.
In particular, you probably don’t want the GPS coordinates of your house publicly available on your blog for everyone to see.
Conversely, as a hobbyist photographer, I want to do the exact opposite for most photos I take.
I would like my camera info, especially the body, lens, focal length, and settings in the image. I recently discovered that software like Darktable can even take a gpx file and photo timestamps to add coordinates to photos taken on a camera without a GNSS receiver.
Most publication and messaging tools strip exif data, which is incredibly frustrating when friends send you pictures taken together as you no longer have the time stamp, nor GPS coordinate.
