Two versions of Roughlock Falls

Here's the finished version(s) of the HDR image started a couple posts back.

Roughlock Falls in Spearfish Canyon is situated so that the largest part of the falls is quite often in deep shadow, while the smaller cascades below are brightly lit. Since this is exactly the kind of exposure problem that High Dynamic Range photography was invented for, I approached this shot with HDR in mind.

The camera was on a tripod and I shot three exposures - ISO 200, shutter 1/15, f22 was the basic meter reading. So I shot two stops over and two stops over that. Combining the three in Photoshop CS5's HDR Pro yielded different effects depending on which direction I went with the slider controls.

So what you have here are the exact same three photos blended in different ways. Whether you like the vintage postcard feel....

...or a more realistic view....

...HDR allows you to get some good images out of a difficult situation.
