Interesting to see these different rates across the board. It seems like those who are shooting 5 to 6 days out of the week each day might have a lower rate but more consistent work and those who shoot a few projects per month have a higher day rate.
I live in the Bay Area and shoot mostly mini-doc and music video content. I bring most of my own gear with the exception of renting for larger project needs. My base day rate goes for about 750 where I will shoot for two to three days. For larger projects its around 1100 or so depending on the scale of work.
