not sure if u guys remember recently there was a thread about a newbie felt offended when a stranger gave him advice that his external flash may not be strong enough during his shoot.
2 weeks back, while shooting in night scene near the jetty near the esplanade outdoor theater, a group of graduates was shooting their grad. shots. the photog (one of them) had a dslr and a zoom lens (looking at it, doesnt looks like a fast lens) mounted on a tripod. from what i can see, the composition was merlion / fullerton hotel as background. he was doing long exposure (from the sound, i reckon its about 2sec exposure) and not popping flash.
some of the group ask him to pop flash but he say it dont look nice and he told the group to hold dead still. those familiar with the lighting condition there at night will know sitting subject along the bench at the edge (not the benches) is very very dim.
i walk over and suggested him to pop flash, his reply is something like "wait the flash hit the background not nice." so i let him be lor. after that he did try pop flash for 1 or 2 shots, but again with long exposure (judging from the sound).
after shooting, he asked his friends to see the lcd and insisted those shot without flash are better.
If that photog is fellow cser reading this thread, may i suggest u stop volunteering to shot for such important occasion (i understand grad gown are rented) or any other important occasion like ROM etc. understand the basic of photography before u go shoot ok?
