High Dynamic Range, or HDR, is a digital photography technique whereby multiple exposures of the same scene are layered and merged using image editing software to create a more realistic image, or a dramatic effect. The combined exposures can display a wider range of tonal values than what the digital camera is capable of recording in a single image.
HDR will tend to be unusable with moving subjects. Software such as Photoshop makes merging the
images easy. Some cameras like the 5d Mark 3 can do this within in the camera.
It’s a great tool when you have very contrasty image as seen at night because it is capturing three different exposure and sandwiches them together to make one image. This gives more details in the shadows and highlights.
• When photographing portraits in low light, a ﬂash can be very helpful. Figure out the proper
exposure of your subject and then ﬁre off your ﬂash . Try lowering the power output of the ﬂash
to minus one or underexpose your image slightly.
• Use a slow shutter speed to let in the ambient light. 1/30th of a second.
• A light modiﬁer is suggested to diffuse the light. Also, if you can get your ﬂash off your camera, you have more options for lighting your subject.
