Bart is absolutely incredible. As I frequently perused numerous high-end, multi-million dollar properties on the market in Petaluma, Santa Rosa, Sebastopol and Sonoma, there were a few that would stand out due to these gleaming "twilight", dusk photos. Weeks later, I somehow ended up on Bart's website and it turns out he was the photographer for many of these very exclusive properties. Bart puts in not only long hours at the photo shoot but gets these photos to you in a timely manner. He is easy to work with and is great with the homeowners/clients. 
If you get the chance, take the time to scroll through some of his galleries on his website. I can guarantee you your search for a photographer will end there. I highly recommend Bart.
