I’m trying to figure out what flash equipment I need for taking indoor real estate photos. I have a nikon 3100 now, but I’m planning on upgrading to a D600 soon so ideally the equipment should be good for either. I’m looking to have at least 3 wireless off camera flashes to start and looking to spend less than $500 (for new) for everything. Does anyone have any suggestions for what I need to connect my 3100 with wireless flashes? I’m still learning and don’t know much at all about slaves, transmitters, i-TTL, etc…) so please be as specific as possible. Ideally this system will work without using my build in camera flash and the off camera flashes can stand on their own or on a stand.
