I used Michelle Garthe. We loved her and we have had many friends who have also used her. I can't remember what she charges, but from memory I didn't think it was expensive. Also, she provides you with a disc of all her photos and she edits a few for you as well. She gave us options for where we wanted to have pictures done, and for us we did a session at Mt Austin park up top of the Peak, and a session in her studio in Midlevels.
We did a shoot with Mel, her website is here. She is very down to earth, engaging and charming. We were extremely happy with the images she made. My colleagues have also had a set they were very happy with.
We used Mel too. She's lovely and the photos are so natural. We would use her again and plan on having her take some photos of the children in another year.
