How to do HDR Photography

HDR photography is an acronym for High Dynamic Range photography.  HDR photography is an advanced photography technique that allows photographers to play with a picture's range in exposures.  This allows a skilled photographer to create an image that accurately portrays the intense levels of light and darkness that exist in natural scenes. 

1. Take your photos.  The first step in HDR photography is to capture your images.  You can use a basic point and shoot camera or a more advanced SLR camera.  Regardless of the type of camera you use, you will need a camera with adjustable exposure settings.  Experts recommend taking your images using three different exposure settings:  EV 0, EV -2 and EV +2.  It is also recommended that you use a tripod when shooting HDR images.  This will stabilize your camera and allow you to capture the clearest images possible.  If you do not have a tripod, you can also use a shutter remote.


2. Transfer your images to your computer.  This will allow you to view your photos on a wider screen, giving you the ability to scrutinize your photos closely.  It is also the first step in using photo-editing software, so you will be one step ahead should you decide to process any of your images after review.  Most photo editing software offers an option to merge your images to HDR upon transfer.  Check to see if this is an option that your software package offers.


3. Review your images.  In some cases, you might have obtained a wonderful HDR image simply by clicking your shutter button.  Carefully review each and every image that you shot, paying close attention to contrast, light and the sharpness of your photos.


4. Post-process the image.  Most cameras have 8 different exposure settings and can allow you to create 8 different images.  When you post-process your image, however, you have an infinite number of settings available to you.  Using advanced photo-editing software, process any images that you desire.  Typical photo processing involves color correction, brightness adjustment and contrast.  HDR processing concentrates primarily on contrast and adjustments between light and dark.  Adjusting the brightness and darkness of your photos during post-processing is the digital translation of adjusting your exposure settings while shooting.  Thus, post-processing can sharpen your images in ways that you are unable to during the shooting process.
