Originally posted by Anvh You can consider doing digitally if the key of the ND is to get longer exposures.
For GND, you can stack exposures and i see you shoot with the K5 that has 13EV of exposure range in RAW so if you underexpose your photo a bit not to clip the highlights you can often up the darker parts to normal level without much problem if you are shooting low ISO.
I know it feels a bit like cheating but it works.
Thanks Anvh.
Well, I have "sort of" tried this technique a couple of times and while it does allow to use a longer exposure time, I believe I had some trouble with the highlights/shadows -- nothing dramatic but still some.
As for stacking the images ... I am all for that and I know how to do it but if what I am looking for is to have long exposure time.
I don't quite get how stacking a bunch of images and wanting to have, for example, the effect of near-cloud-like moving water ... ?
Care to tell me how to do this?
Example: daylight, bright; moving water: I want to have this "sliky" effect, so I am going to need a "very" long exposure time.
If I am already using ISO 80 , stop down @ f11-16 ... with NO filter(s): I am quite sure the shutter time will still be too short, no ?
I have used the Cokin system with my DA*16-50, and it works great, but I find the whole gear sometimes a little too "busy" (akward/cumbersome).
