A great discussion came up within a pro photography community about business cards. The discussion boiled down to:
To put photos on your card or not.
There were great arguments for both sides. One of the most successful photographers I know actually puts a picture of him and his partner on his card. I know the “real estate” cards pop up in your mind, but be more creative and I think you will come up with a great card with personality. You are selling you, after all. Not that I think you NEED to do this, but it is a great 3rd option that many photogs overlook.
