Carpal tunnel or no carpel tunnel, I needed do some serious post-processing work to lighten up the photos of Krista on the couch. There wasn't a lot of light coming into the living room. All I had was my flash shot through an umbrella and a not-very-reflective poster board positioned at camera right. To compound matters, the 70-200mm lens I rented "only" opens up to f/2.8. To further complicate things, Krista moved around a lot and I have shaky hands, so the exposure time had to be relatively brief. The ISO was set to 100, so I could have easily bumped that up to 400 without introducing too much noise. This would have pushed up my exposure by two stops. So why didn't I raise my ISO? Ummm...I forgot to do it. :-(
Here are the nitty gritty details:
Exposure: 105mm focal length, 1/320 sec, f/2.8, ISO 100, 2:47pm.
Artificial lighting: Flash shot through umbrella at ~1/4 power, ~50mm zoom, 8:00 camera left, umbrella 3 feet away and 2 feet above subject, white poster board reflector propped up on couch at 3:00 camera right, 2 feet away from subject.
Post-processing in Lightroom: +1 stops of exposure, increased fill light, sharpened, increased color temperature.
