HDR Photography at Typhoon Shelter, CWB.

One thing that you should always keep in mind while taking pictures, is that your camera does not have the same capabilities as your eyes when it comes to seeing both bright and dark tones in a scene. Our eyes are equipped with the most advanced technology, allowing us to see and perceive colors and tones no human-made electronic device can even come close to. This range of tones and colors is known as “dynamic range” in photography, which has become a key performance metric on modern digital camera sensors – the more dynamic range, the better the sensor.

If you have been using a digital camera for a while, you most likely ran into a similar situation as the one I described above, where you would take a picture and parts of it would either be too bright or too dark. No matter what settings you tweaked on your camera, nothing would seem to help, despite the fact that your eyes were seeing everything just right. If you switched your camera to manual control, you could brighten up one area, which would darken another and vice-versa, but no settings would correctly expose both, all due to the large dynamic range of the scene.

What is HDR?

HDR or High Dynamic Range Photography is a post-processing technique that uses multiple images of the same scene shot at different shutter speeds to combine them all into a single photograph. The result is an image with the most amount of detail in both shadow and bright areas of the image, close to what the human eye would see. Although it is ideal to use multiple images of the same scene, you could also create an HDR image from a single image, as long as it is shot in RAW format. Hence, there are two methods of creating an HDR image: a) from a single image and b) from multiple images.

HDR Requirements

1. Digital camera (preferably a DSLR), iPhones and some Android Phones have HDR built-in

2. Tripod (for multiple exposures)

3. Adobe Photoshop or some other image-editing tool

4. Photomatix Pro or other HDR software that came with Canon or Nikon DSLR's (optional)

Although you could get away without a tripod by shooting hand-held in brackets and let HDR software automatically align the images, it is still recommended shooting with a tripod to get the best results.

Camera Settings

For best results, it is highly recommended to do the following:

1. Shoot in RAW if you can.


2. Always keep the aperture the same between the shots, so I recommend shooting in Aperture Priority mode. You do not want to have images with different depths of field.

3. Set your camera metering to Matrix (Nikon) or Evaluative (Canon) to let the camera pick the best exposure for the whole scene. This will be your middle exposure.

4. Use the bracketing function of your camera and shoot in 2 EV steps if you are doing three brackets or 1 EV step if you are doing five brackets. For example: -2, -1, 0, +1, +2 works great for most situations.

We're shooting at the overhead bridge between Victoria Park and Typhoon Shelter in Victoria Harbor. We can catch a red sunset with the Hong Kong and Kowloon skyline silhouetted against a setting sun, a perfect shot for HDR photography.

    Got the technique on HDR and learn the trick how to make the landscape with detail at dim portion. Next, plan to buy the photoshop cs for the trial. Thanks organizing such great gathering and sharing.

      Don't get Photoshop CS yet. Try the Photoshop Elements trial version. It's much easier to use and almost as good as Photoshop.

  • Syarif

    By MTR at which exit door at causewaybay?? And than which direction I should go, Sorry to ask the location detail

    September 7, 2013

    • ron

      Syarif, go to the top of this page and please read about where the location is. It says 'Victoria Park, Fountain (next to Windsor House, Causeway Bay). After you read the rest of it, you should be able to find us. It even tells you which door to exit from and which direction to turn. If you click on it, it shows a location map. It's very informative if you care to read it first before asking this question.

    Looks like a bright sunny day for HDR this Sunday. We'll be shooting next to the yacht club and you can descend the overhead bridge to shoot the boats, too. Not so easy to shoot boats bobbing up and down in the water. Same for the cars on the highway next to it. Remember, RAW files are already High Dynamic Range photos. That's where you sometimes just take one shot in RAW only. Then use Photoshop to create 3 separate exposures and make your HDR photo from there.
    I'll show this using Photomatix and/or Photoshop.
    The usual way to shoot HDR is, of course, 3 separate shots. But only on non moving scenes. See you guys on Sunday!!

  • ron

    I might bring my laptop and show some of you how it's done in Photoshop.

    2 · September 3, 2013

  • ron

    Even if it rains, we'll be standing in shelter on the bridge. Do bring a small brolly if you can. I'm not going to cos I'm water proof.

    September 3, 2013

  • Andrew

    Look forward to it. See you there!

    For those with Photoshop CS3 and later versions you don't really need Photomatix. For those who don't know how to do HDR in PS I've posted a second video above that' easy to understand, simple and really works.

  • Jovi M.

    well if you know post processing you can do hdr by editing using one picture only.

    August 20, 2013

    • ron

      Both ways work, as no one can tell the difference after it's processed. But bracketing is the better way, of course.

      August 21, 2013

    • Joerg Z.

      i usually use bracketing but have for old images also used one single Raw file saved in three differed exposures and combined again into one HDR. surprising how well this also works. It is surprising that the cameras do not use all this information in a RAW file anyhow. There should be a better RAW converter in camera or LR that uses all these info that is on one RAW, so that we don't have to make these tricks...

    i will try HDR this time :) thanka for organizing

    August 20, 2013

  • Syma

    I've never done HDR so this should be fun :D
