HDR Article Notes

• HDR allows a photographer to make a photograph more dramatically dynamic by merging different exposures of a same scene.
• HDR is used in video games as they allow to render a same scene under a variety of lighting conditions.
• Darkens highlights and brightens shadows so that details can be retained in each area. 
• To create an HDR image need a set of bracketed images and a software, such as, Photomatix Pro, where the images are aligned and merged into a single photo.
• Contrast is then reduced through tone mapping.
• To take an HDR image you need a tripod to keep the camera as stable as possible between shots.
