Hi,
In order to syn the flash and use a bigger aperture on bright backgnd,
is it a feasible idea to use ND filter ?
Tks
Thanks Guys ...i suppose :bsmilie:
Btw,
For taking slow shots of waterfall etc on bright day,
is ND8 or ND400 is more suitable ?
I suppose ND8=3 stop and ND400=9 stop.
Pls correct me if wrong.
Thanks.
ND400 is actually around 8.6~8.7 stops, but 9 stop is close enough I suppose.
To get the approximate shutter time, just take X from NDX and multiply your shutter time. For example, a 1/200s shot will take 1/200 * 400 = 2s with a ND400 on. That sounds about right to smooth a waterfall. On the other hand, 1/200 * 8 is not quite enough
Hi,
2 more questions,
how many stop is ND110 filter ?
Is it necessary to pre-focus before putting on the ND filter such as ND400 ?
Thanks
