For those interested in long exposure conversion, this is a useful reference i found. Do remember every stop is a multiplier of 2. A lot of people get confused and ask, don't the aperture and ISO affects the shutter? Yes.

Give u all an example. I shoot a scene at ISO100, aperture f8 @ 1second and I shoot another scene at ISO400, aperture f11 @ 1second. The exposure is the same. And when we talk about exposure, forget about the noise, the depth of field and be concerned with only getting the "right" exposure for the scene or subject.

I shall use the example of a ND8 (3 stops).

w/o filter

Take a shot at ISO100, f11 @ 5s

with ND8 filter

Take a shot at ISO100, f11 @ 40s

So how do I arrive at 40s. Simply take:

5 * 2^3 = 40secs (note 2 to power of 3. So if ND16, its 2 to power of 4 and so on)

So if u have a ND400, it would be

5 * 400 = 2000s = 33 mins 20secs


So what does all these mean? U can take longer exposures of scenes to capture cloud motions, make waters super silky smooth etc. With higher stop ND filters, U can eliminate motion on streets in broad daylight with longer exposure time.

Do note that ND filters is not 100% neutral. Even the best LEE filters or Singh Ray etc do have slight tendency of color casts at extreme long exposures.

w/o filter

with ND8 filter

Take a shot at ISO100, f11 @ 40s

So how do I arrive at 8s. Simply take:

5 * 2^3 = 40secs (note 2 to power of 3. So if ND16, its 2 to power of 4 and so on)

So if u have a ND400, it would be

5 * 400 = 4000s = 1hr 6 mins 40secs

Great effort, thanks buttie. :thumbsup:

dont bother with shots over 1min... cos you will get long sexposure noise for digital cameras. even star trail shots, do it in multiples of 30s, rather than one long exposure of 30mins.

End of this month good for low tide shoot. 0.2meters on 30th and 31st Jan at around 1800hrs one. Will organise one outing end month for sunset ya.
