Carole,
Good to see another Brit in the forum

I have just taken the plunge and gone totally digital, I bought a Canon D30, laptop etc etc. I mainly take location pet portraits and the D30 has totaly changed the way I work. I am also finding that my "commercial" work has increased, I have just finished a job photographing Pet Coffins...yes you read it right !!
Clients are constantly amazed at seeing their pictures on a screen (I currently use a laptop but a data projector is top of the wish list). I have a number of weddings booked this year and I plan to borrow a projector to show the days photographs to the B&G and guests in the evening. A good time to take orders ...!
Will keep in touch and let you know how it goes.
Regards.
Nick.
