I shoot portraits, products, families, cars, macro, and more — not because I couldn't pick one, but because good photography is good photography. The principles don't change. The light doesn't lie differently depending on the subject.
The deli doesn't apologize for making both a perfect reuben and a perfect egg sandwich. I don't apologize for being versatile. What you get every time is someone who cares obsessively about your result — not just your genre.
