Five frame long exposure HDR with a ten stop ND filter
|This waterfall was created by water seeping (gushing) under an old magma field and exiting along this fault line in a set of falls 200metres wide.|
|Further upstream at Hraunfosser this was a long exposure HDR shot |
It doesn't work because all that movement in the cauldron smoothes out to nothingness.
Exposure 20secs @ f11
|Same place at 1/25s |
Clearly super-long exposures work for some scenes but not this one!
