We were hiking down from the SAC House. It was raining and we looked for shelter under some fir trees to rest. It was very dark - too dark for a f4.0 lens. So I light the scene with my flash and am posting it here, because I like tha natural ambiente and the dusk in the background.
Light: 430EX on camera, 50mm, -2EV, ambient also dialed down 0.67 EV,
