I have just acquired a 4 stop Hoya ND filter and wanted to try out the effect of shutter speed on waves breaking over rocks. I had a limited opportunity a couple of days ago at Noosa in the National Park and here are three shots taken about an hour after sunrise. Some of the things I took away from this exercise were
- Do your homework on tide times - I would have liked a higher tide here
- Take some lens cleaning fluid with you when using a multi-coated filter where there is salt spray
- Shutter speeds of around 1/5 to 1/10 sec stop the water but do give some desirable "flow" effects
- Shutter speed of around 1-2 seconds give a slightly dreamy look to the water without over-doing it
- The closer to sunrise, the more interesting is the light
- Timing of when the shutter is released in relation to when the wave breaks is important. I feel that it works best if you operator the shutter a little after the wave breaks when you get water rushing around and cascading over rocks
I've posted these three images in my order of preference (favourite first) - I'd be interested to hear what you think of the images and also if some of my comments strike a cord with anyone else.
