Comparison
Another shot in my series of experimentation with image stacking. This was shot has no artistic value but demonstrates the potential of this method to replicate the effect of a heavy ND filter without getting colour casts and potentially with sharper non-moving objects through use of a higher shutter speed.
This comparison shows a quick 5 shot stack (on the left) and an individual image on the right.
I took this sequence of 5 shots hand held over about 12 seconds i.e. one shot every 3 seconds.
Clearly the results would be better with a tripod and shutter release to avoid movement of the framing between shots.
I can see that maybe 5-10 shots over what ever time interval you want to replicate could easily replicate the effects of a 10 stop filter with some ancillary benefits as follows:
- use of higher shutter speed means less chance for camera movement and loss of sharpness
- higher shutter speed means tha moving objects (like cars) could be captured. It may be possible to stack shots to captur a trail ofa moving car. This is something the ND filter generally can't achieve as the car flashing through the scene won't give enough light to register (unlike on a night time long exposure). This is both a positive and negative aspect.
I would be keen to trial the concept of capturing car trails during daylight and similarly something like ferry trails on the harbour whilst having long exposure water and full daylight.
The same principals could be applied to seascapes and wave motion.
