Hi there, I just come across with bulb mode for long exposure photography. Normally I do a exposure with 15sec only (cuz that what my current camera allow me to do fuji S5200 is without bulb mode).
I know is stupid to ask how to calculating the shutter time require fro bulb mode, where my camera dun even have the bulb mode function.:sweat:
But anyway, here goes
when aperture f-number = Require Shutter Time
2.8 =15 sec
4 =30 sec
4.6 =60 sec @ 1 min
8 =120 sec @ 2 min
11 =240 sec @ 4 min
16 =480 sec @ 8 min
If the correct exposure is f 2.8 at 15 sec.
then the other on-going estimation are calculate like this??
thank in advance
