I got to thinking earlier how it’d be handy to have a small popover thing on my photos that shows the focal length, shutter speed, aperture and ISO of the shot. Turns out, there’s a JavaScript library that can read EXIF data, and it’s super simple to use. About half an hour of tweaking later and it’s done. Here’s a picture of my daughter looking unimpressed, to demonstrate:

I’m only showing focal length and aperture because for the kinds of pictures I take, and the size they’re shown here, shutter speed and ISO are basically irrelevant.
