HDR Photo Gallery

  You can read what HDR (high dynamic range) photography is by visiting my HDR Photo Gallery, but in the meantime if you are you wondering what you need to be able to take HDR photos yourself, here's a list of what it takes.

Camera:
  1. A digital SLR camera set to the "aperture" setting (on a Canon camera this is the AV setting on the dial...perhaps someone with a Nikon or other brand of camera can post the equivalents in the comments section below?) 
  2. The ability to specify "bracketing" for your camera (Select AEB under the camera menu for a Canon camera, and then spin the wheel and choose the level of exposure value spacing you wish to shoot at - I always use steps of 2)
  3. Set your drive setting to "multiple exposures" (with AEB set, your Canon camera will take 3 exposures while you continue to depress the shutter)
Software:
  1. Photoshop CS4 or higher (CS5 has greatly improved its HDR handling) or other proprietary HDR software such as Photomatix or Dynamic Photo HDR to process the bracketed images into one HDR file which can then be manipulated in a process known as "tone-mapping".
Other Recommendations:
  1. Whenever possible, shoot HDR brackets using a tripod since you don't want any movement or shake while taking the multiple exposures since the individual images will be layed on top of each other and any movement while the photos are being exposed will result in ghosting in the final HDR image.
  2. A cable release or wireless remote to further reduce the risk of moving the camera while the bracket is being exposed.
HDR is a lot of fun and you can come up with some amazing outcomes. You'll be pretty surprised. Once again, you can see some examples and read more about what HDR is at my HDR photo gallery.

And you are welcome to post any of your examples of your own HDR images on my Facebook page at http://www.facebook.com/photosbyjohncorney.

Pink Bromeliad #4 aechmea fasciata

Posted
Pink Bromeliad (aechmea fasciata) This beautiful bromeliad is flowering in a pot on my patio at the moment. I guess it must like my garden. I had it sitting under some trees in a pretty shady but bright spot for most of the last year since one of my neighbors moved and gave it to me. Once I saw all the blooms coming I moved it into the sun while it puts on its show. Its common name is urn plant or urn flower, and its botanical name is bromeliad aechmea fasciata. These plants are related to the pineapple, did you know? Please feel free to post any comments.

What is Bokeh?

Posted
Columbine at the Huntington Library gardens, shot at f/4.5 to throw the background into bokeh. © John Corney A photograph I took of columbines at the Huntington Library gardens recently has such a beautiful bokeh effect that I thought I'd use it as an excuse to talk about bokeh today — what it is, where the word comes from, and how to get it in your own photographs. What Bokeh Actually Is The word bokeh comes from the Japanese word boke (暈け), meaning "blurred" or "haze." It started being used by photographers in the late 1990s to describe specifically the quality of the out-of-focus areas of a photograph — not just the fact that the background is blurred, but how aesthetically the blurring is rendered. Good bokeh is creamy, smooth, and pleasing. Bad bokeh is harsh, distracting, or busy. Two lenses can produce the same depth of field but very different bokeh. It's pronounc...

Bryce Canyon Rock Warrior

Posted
While walking back up from the bottom of the Queen's Garden Trail back to Sunrise Point I noticed that in this rock formation I could make out the face of a Mayan or Aztec warrior chief. If you click on this image and look just below the center of the bigger image hopefully you'll be able to make him out. He has a big nose and a high headdress. It was a pretty amazing sight. I wonder if other people have ever picked this out. I think a lot relied on the shadows that were being cast at the time by the sun. Perhaps it doesn't look like a warrior if the shadows aren't just right. Bryce Canyon National Park website
