假設你晚上於馬路旁影向前行的汽車，用長時間曝光 (1/8s) 再加閃燈凝固車身

前廉同步
會見到長長的燈光出現於車的前方 (唔自然，以為向後駛)

後廉同步
會見到長長的燈光出現於車的後方 (好自然，以為車向前駛得好快)

***唔好嚮條街亂試，你影完 D 司機會即刻 Dup Break，以為差佬影快相

後廉同步夜晚慢快門+閃燈影合照有個好處，因為大家習慣左閃燈閃完就當影完走晒，用前廉好易搞到成班人郁左，用後廉成功機會大好多。

用後廉同步閃光有一點要注意, 就係主體移動方向要o係拍攝平面內, 如果唔係,你freeze到o既主體會係一個out of focus o既影像. 所以如果主體係向拍攝者前後移動o既話,就要用番前廉同步閃光方法!

reflexboy ching.... good !!!
the 1st time I heard that 後廉同步 is not good....

其實問題係出於o係應用層面方面! 無咩話絕對好或絕對唔好! o係適當o既情況用得上o既野就係好野.

U should try yourself to spot the difference la.
it doesn't have much different with standard flash syn shutter speed. But....Take this exercise and u should find the great difference: when u want to take a portrait picture at night with Victoria harbour as background. You will need a few seconds...Try the two flash method n will know the difference and that's why i have set 後廉同步閃光 in my camera as default. ho ho ho.
