Video: Ghosting and HDR Efex

HDR Efex has a ghost removal mechanism built-in for removing those ghosty artifacts that can occur when something moves between frames in a bracketed set. It's pretty easy to use. It's only somewhat effective. I am going to launch into a merge of the bracketed set here in HDR Efex, and when I get my Merge dialog, which lets me choose which images to merge, that's already filled out, I have Ghost Reduction Method. You've got a couple of choices here. Adaptive or Global. We will leave it on Adaptive, but set the strength up really high.

Shooting and Processing High Dynamic Range Photographs (HDR)
4h 55m Intermediate Jul 22, 2011

Viewers: in countries Watching now:

In this course, photographer Ben Long describes the concepts and techniques behind high dynamic range (HDR) photography, a technique used to create images that have a wider range between the lightest and darkest areas of a scene than a digital camera can typically capture. The course begins with some background on dynamic range, on how camera sensors detect shadows, and on the kinds of subjects that benefit from HDR. Ben then describes and demonstrates several methods of generating HDR images, starting with single-shot HDR, which relies on masking to subtly enhance the dynamic range of a shot. Next, the course covers multi-exposure HDR, which involves shooting several photos of a scene, each at a different exposure, and then combining them using software tools. Ben demonstrates how to use Photoshop and the popular Photomatix software to process HDR images whose appearance ranges from subtle to surreal.

Topics include:
  • Understanding how the image sensor detects shadows
  • Capturing a broader dynamic range
  • Knowing when to use HDR
  • Finding good HDR subject matter
  • Using gradient masks to improve dynamic range
  • Merging in Photoshop and processing elsewhere
  • Dealing with ghosting
  • Reducing noise and correcting chromatic aberrations
  • Handling HDR images that seem flat
  • Combining HDR and LDR (low dynamic range)
  • Selective editing with HDR Efex Pro
  • Creating panoramic HDR images
  • Creating an HDR time lapse

Ghosting and HDR Efex

HDR Efex has a ghost removal mechanism built-in for removing those ghosty artifacts that can occur when something moves between frames in a bracketed set. It's pretty easy to use. It's only somewhat effective. I am going to launch into a merge of the bracketed set here in HDR Efex, and when I get my Merge dialog, which lets me choose which images to merge, that's already filled out, I have Ghost Reduction Method. You've got a couple of choices here. Adaptive or Global. We will leave it on Adaptive, but set the strength up really high.

Hit OK and that's going to work here. As for how much strength you should use and what the trade-offs are, use too much strength, you can start introducing other artifacts. So you don't want to go any higher than you have to. As for Adaptive or Global, it really depends on how spread out your ghosting problems are. So you may just have to experiment and the experimenting can be a little slow because you have to do a full merge every time. But as you use it more and more, you will probably start to recognize, oh, last time when I had this kind of similar ghosting problem, these were the settings that worked.

So, here we go into the software and you can see that didn't work very well. I had ghosting around his head, I am looking down there at the loop, and let's just go ahead and zoom in. I had ghosting around all of their heads. Let's cancel out of there and start the merge again and this time change it to Global and kick the strength up real high. Say OK and let it go through another one. Now if this does not end up working, we can use merging in Photoshop and turn on its ghost removal and do the trick that I showed you before.

And then with that document open in Photoshop, just go into HDR Efex on that document and it won't do its merge. You will just be able to go right in the tone mapping. And there opens up and here I render. Things are little better, although he still got a ghostly ear and up here, fixed the ghosting on his head, but left a strange green line moving through him. I got a couple of options here. I could try to retouch a lot of these problems.

That's an easy cloning to get rid of that. This kid's face really didn't fair very well and there will be a lot of retouching to do throughout this image. You know I am going to just call this a fail, I think, and do what I just described earlier. A little bit of ghosting here and some what appeared to be weird ghosts and halos around him. I think this is a case where I have to do my merge in Photoshop, let it take care of the ghosting, and then open the results in HDR Efex. Sometimes this will work. Sometimes it won't. Fortunately you have an out if you've got some other ghost removal tools at your disposal.
