I'm seeking advice for creating a portable (able to fit into my car trunk) portrait studio. Quality that will endure transport, fairly easy to setup and teardown. Gear for headshots, corporate group shots, etc. Lighting, (lights with a built in battery or is it better with a external power source?), stands, a portable backdrop, modifiers...(I have a Sony A7R and a 36-70 lens. I will be purchasing an 85. I also have a sturdy tripod).
If all things are equal, I would rather save a few dollars with an "off" brand. But quality, durability, realability are more important than price. Thanks in advance.
