A little while ago I shot an editorial for ION Magazine titled “Where Eagles Dare”. We shot it at night using all available light and other nonconventional lighting sources like emergency flares, and sparklers.
I shot all this using an ISO of 6400 which allowed me to shoot hand held and get the action shots and sense of movement I needed for the story. The main issue with such a high ISO is the digital noise, but since I was shooting in black and white it actually complimented my shots. I really enjoyed this shoot, and loved the raw and gritty results which were exactly what we were looking for.
