Photos are finally up on Standard Chartered Marathon's website (link) and I'm glad that most of them came out ok!
Had helped out the pacers with their Standard Chartered Marathon profile photos and it was a simple setup. I had initially planned to use strobes in a shaded area so as to keep the lighting consistent among the runners, but thankfully the shade we found had a constant lighting and hence I just stuck with a natural setting instead.
The last two shots were at a different location, thankfully they came out alright too, and rather consistent in color apart from background.
Less than 2 weeks away from race day, good luck guys!
