Title: Waterfalls, long exposures and motion
Post by: dreed on January 01, 2014, 07:03:21 am
I'm going back over a lot of my waterfall shots and noticing a problem that I hadn't really thought about before and that is that waterfalls all seems to generate a certain amount of wind, whether it be small or large, and that this introduces motion blurring in plants around them when you go for the "milk look" with running water.

How do people try and manage this issue?
Tips?
Tricks?

I haven't tried this, but I would be tempted to take an additional shot at fast shutter speed, and then blend these selectively in PhotoShop.

As Eric says, take a second shot.  There is another reason to do this as well.  Usually your "slow" shot will be at a small aperture to get a slower shutter speed, and diffraction will soften details.  When this matters I will take a second shot at f/5.6.  An example of this is to see fine detail in boulders in a fast moving stream.

Justin Reznick has a nice ebook in which he talks quite a bit about multiple exposures and blending for just this purpose.  You can access his ebook through flatbooks.
