Every lawyer needs a digital camera for their exclusive use.  I'm not talking about sharing one with the entire office, or using your camera phone or the one from home (when you remember to bring it).  I'm talking about a small, digital camera (like this one) you can keep in your pocket, briefcase or purse. 

I take mine everywhere.  Here are a few not-so-obvious reasons lawyers should, too:

1. To remember what your clients look like.  Go ahead, admit it.  When you look through your files at the end of each month (you do that, right?), you always have at least one client's name you can't put with a face.  How about the times you get a call from Bob Smith, and you can't remember just exactly who Bob is?  Every time you retain a new client, take their picture.  Upload it to your practice management/contact management program and print it out to put inside their file.  Even better, also put it in an album of past and current clients (like a yearbook) and you'll never be caught scratching your head wondering just who that person was you just bumped into at the supermarket.
2. To make sure you send your bills out on time.  Take a picture of something you want (a new car), or something you love that costs you money (like your children), and clip that photo on top of your stack of bills when you review them every month.  The picture will remind you just why you do what you do, and motivate you to get your bills out on time.
3. To make copies and turbocharge your whiteboard.  This tip alone could save you (or your clients) the cost of a camera in less than six months.  Sign up for a service like ScanR and send your photos of documents, business cards or whiteboards in and have them converted into .pdf files for free.  This can save you $1.00/page or more vs. paying for copying court files.
4. To help your clients find the courthouse.  Next time you head to the courthouse, take pictures of the parking lot, the entrance, and even the place you want your clients to meet you.  Send the pics along with your letter telling them about their hearing, and they'll be far more likely to be on time.
5. To capture the cool things you see.  There are always things we see that we wish we'd remember.  Take a picture.  What you'll find is you remember more things, and you'll also start to become a much better photographer.
