셔터속도 계산

125분의 일초, 60분의 1초.. 별로 감이 안 오는 것 같아서 한번 계산해봤습니다.
0.008초, 0.016초.. 감이 조금 생기는 듯 하네요?? ^^

빛이 1m가는 시간

내친김에 스튜디오 촬영시 셔터속도와 스트로보 발광시간과의 관계를 생각하다가 빛의 속도도 한번 계산해보려고 했습니다. 빛이 1초에 약 30만km(정확하게는 2.99792458 x 108m/sec라고 합니다)를 간다고 하죠? 그럼 1미터를 가는데 걸리는 시간은?

1초 : 299792458m = x초 : 1m
x초 = 1/299,792,458 = 3.3356409519815204957557671447492e-9

약 3억분의 1초!! 아무리 빠른 셔터속도라 해도 비교가 안되는군요~~ ^^
