Black and White photos

Black and white photoes are usually great.  Well, it is what I think.

Often, those photos are outdated and their ages shows.  It is what makes their charm.  Photographers had to be more careful and more knowledgeable.  It was truely an artform.  I don't think I would be able to be in their places.  It was also time and money consuming.  It wasn't as easy as today for making some correction to the photos.

One thing I would like to learn how to do: sepia tone photos.  I would like to know how to do it.  I am sure it is easy to do now with all the programs that exist today.  I like the retro look it gives to the photos.
