I went out on a shoot last night. There were a number of shots I have been meaning to take, but the conditions haven't bee favourable. This first one I have been I visioning for months. There's an on-ramp into Stoney Trail (Calgary's ring road) which has runoff basins on either side. They fill with the runoff from the highway, and the rainwater is meant to evaporate, but never seems to.
I like to shoot frames in triplets for HDR purposes. It actually achieves two purposes. The first frame is perfectly exposed. The second is 2/3 of a stop over, and the third is 4/3 of a stop over. This gives me the ability to bring up the dark & shadowy spots. Then after I apply the HDR process, I can always play with the exposure rate to get the mood I am looking for, without losing the details.
The challenge To shooting triplets at night is that you have to remember to be situationally-aware ! I was so concerned with getting the exposure correct, I failed to notice the traffic. The first exposure was about 4 seconds, the second about 6, and during the final 9 second exposure a pickup truck came racing through my shot !
