More with ND filters.

Decided to make the most of travelling on the DART today, so thought I’d have another play with ND filters.  Having seen this technique on the Shaw course I wanted to have a go.  Initially I’d tried this with Supercars but they were going pretty fast and while I got close to the effect I wanted I didn’t really get a chance to play.

ISO: 100
Shutter Speed: 1/4 sec
Lens Model: EF50mm f/1.8 II

As you can see, the blur is there but it’s really indistinct as to what is actually moving.

So this afternoon, as there was a bit of time before the next DART I dug the camera out and put an ND4 filter on.  This means that the lens will be effectively 2 stops “darker” in terms of exposure.  As you can see below from the caption the shutter speed ended up at a slower () for the same exposure.  Without the ND4 filter the shutter speed would have been significantly faster and the motion would have been stopped.
