Movement in HDR Images Can Be Bad - or Good

"How do you deal with subject movement in HDR images?" That's one of the most frequently asked questions I receive in my HDR seminars and on my Exploring the Light Workshops.

Well, there are two answers to that good question - because paying attention to subject movement (as well as camera movement) is very important in HDR photography.

1 - Subject movement can be good - when you are creating HDR images of fast-moving water and clouds.

Even exposures of several seconds can help to create beautiful images, as illustrated here by my HDR image of the New Croton Dam.

2 - Subject movement can be bad - when photographing people. For example, check out the close-up of the man's hand in the top set of illustrations (San Miguel de Allende, Mexico). Even though I asked him to stand perfectly still, he still moved his hand ever so slightly in a few sets of images.

When photographing people, my advice to HDR photographers to take several sets of pictures - with the goal of getting at least one set with no subject movement. Plus, of course, asking the subject to stand perfectly still.

You'll find more info on HDR imaging in the next update (late March) of my 24/7 Photo Buffet app and in my next book (due out in late April), HDR Photography Secrets.

I used movement in an HDR once to create a ghosting effect on purpose. I was at the travelling Moving Wall Memorial for Vietnam Vets and took some bracketed shots of a part of the wall and then using the camera timer took 3 more bracketed with me standing at the wall. Once I did te merge of the 9 or 12 images, it was a nice HDR with my ghosted into it. A unique take on the pic of the man leaning against the wall with faded soldiers in the wall. It is on my blog somewhere onthe HDR archives. if you're interested.
