EXIF Viewer is a simple application that does what it says: shows EXIF data. The information is shown in a table and can be copied and pasted as text into other applications:

It can't interpret the ISO data from my Canon S3, but then nothing outside of Canon's own software does that, so this is no big surprise. To use it I just drop a selection of images onto the application icon and it creates a window for each image.
