I can't stress enough how important it is to have a well designed and original business card that creates an impact. A photographer is an artist, and his business card should reflect his artistic capabilities, his brand, and his taste.
Being a graphic designer myself, I designed my own card.
For the paper, I chose Wausau Royal Complements Bright White stock triplexed for a very heavy feel, and I went with letter press printing. It really makes the card stand out, and actually makes a sound when you drop it on the table.
Although they were quite expensive, at approximately $1.80/piece, I think it was worth every penny.
Every time I give one of my cards out, they are treated like a piece of artwork.
The company I used to print the cards is "Studio on Fire" and Ben was very helpful, patient, and professional.
