HDR Photography: What You Should Know And How To Shoot It

Have you ever attempted to shoot a high-contrast scene only to be disappointed when the photos you took simply don't do it justice? Don't be alarmed; it's not you or your camera. Even when the exposure is correct, some situations will always have blownout lights, dull shadows, or both. Even though finding a middle ground in these instances is practically difficult, there is a way.

This age-old quandary can be resolved thanks to the wonders of HDR processing. What exactly is HDR photography? Here's a brief summary of what it's about and how it is used.

How to Create an HDR Image

Step 1: Take many images at various exposures.

The idea here is to shoot three separate exposures of the same image, with no movement between them. Your bracketed images will be separated by two stops.

Manual or Aperture Priority mode is recommended, although Program mode is equally acceptable. Here's what you should do: Locate a steady location for your gear and fasten it to it.

Configure your cable release, mobile phone app, ir remote control, or selftimer.

Set your focus and composition like you would for any other shot.

Set up your camera as you would for a standard exposure and snap your first shot. Alternatively, if your camera supports Auto Exposure Bracketing, dial in your settings, fire off your series of images, and disregard the steps that follow.

Take a second, brighter image to bring out the shadows. Turn the Exposure Compensation dial to +2 if you're in Program or Aperture Priority mode. In Manual mode, half your shutter speed, then halve it again.

Take a third, darker image to bring out the highlights. Turn the Exposure Compensation slider to -2 if you're in Program or Aperture Priority mode. In Manual mode, double your shutter speed, then double it again.

And there you have it! You have now three images with varying exposures.

Step 2. Combine Multiple Images Into One

The aim is to combine (blend) the three separate exposures into a single 'High Dynamic Range picture.

Download a copy of Aurora HDR or any other software of your choice.

Click "Open Image" from the Welcome screen.

Navigate to the bracketed images on your hard disc, pick all three, then press the "Open" button.

If you were shooting handheld, check the "Auto Alignment" box (and you may need to start the process again with this ticked if you find later that your images have not lined up correctly). If in doubt, turn it on.

Select the little gear icon. If your snapshot includes subjects that may
