Hey class!  This is my first attempt in posting here, so let's check it out and see if I did it right!  I am uploading a .NEF file, which is a RAW photo file.  As you can see, it is terrible under exposed.  Download this image, open it in Photoshop and using the RAW viewer, which will automatically open, you can adjust the settings and get a perfectly exposed photograph.  FYI, this was taken in Anzo Borrego and it is of a sculpture by an artist by the name of Richardo Breceda.  He's brilliant!
