What equipment do you use?

I'm a canon gal.
Partially because it's what I started with, but mostly because I love it!
I use a Canon 6D for the majority of my photos, and my favorite lenses are Canon's 17-40mm f/4 lens and  24-105mm lens.
The majority of my editing is done in Photoshop, though I also use Lightroom from time to time.

Do I have to print my photos through you?

No!  All of your photo sessions include print releases so that you can print your photos whenever you want from whomever you wish.
I have some favorite printers, and I'm happy to make recommendations, but where you print is up to you.
