I think that a photograph should speak for itself. That said, I do like to add a description highlighting interesting facts about a photo or about the circumstances when it was taken. For instance, the photo on this page was taken in a milonga (tango club) in Buenos Aires. The light was so dim, I could only shoot when the dancers passes beneath the halogen lights.
I keep an account at SmugMug where I display a greater number of photos on various subjects. Please visit me at mikeharrisphotography.smugmug.
I also post photos using Facebook. You can find me by entering mike harris greenwich.
