The widely recognized master of landscape photography Ansel Adams developed a high-level skill in dodging and burning, which is actually a form of manual tone mapping done today automatically by HDR software. In the late 1800s, pioneering darkroom wizards such as Gustav LeGrey sliced negatives and used different exposures to balance out tonality in dark versus light areas of photographs. Long before photographers sat at a computer to work on images, they were blending different pieces of differing exposures together in a darkroom. Each method has its own plusses and minuses and there are different strategies to applying each technique that will bear better results in some situations as opposed to others.ДЄnd before the purists out there grab their pitchforks and torches, it pays to remember that high dynamic range imaging is not new and is certainly not exclusive to digital photography.

If youвЂ™re not going to adopt a graduated neutral density workflow because you donвЂ™t want to bother with fragile, expensive, and sometimes limiting filters, then you have to choose between either HDR or MEB and plan both your shooting and your post-processing accordingly. This method works well for scenes where GND filters fail, such as mountain landscapes or cityscapes with portions of sky showing.

The third means of achieving a wide dynamic range image is by taking two or more images of differing exposure, typically by varying shutter speed or ISO, and then hand-blending these together in Photoshop as layers using layer masks. Multiple Exposure Blending (MEB) or вЂњBlendingвЂќ

Prominent examples of HDR software are Photomatix, Nik HDR Efex, and the native interfaces of either Photoshop or Lightroom. These images are then fed into HDR software which apply algorithms to blend portions of the images together through the use of tone mapping or exposure fusion automatically there is also some degree of user control over the blend. Bracketing refers to taking a set of photos and changing only 1 setting in the Exposure Triangle (typically the shutter speed) to achieve a set with a range of 1, 3, 5, or even 7 EV so that you have some underexposed images, some overexposed images, and some just in the middle. There are dedicated stand-alone software and software plug-ins that can create high dynamic range images from a carefully constructed set of вЂњbracketedвЂќ photographs. But the technique is dated, has limited use, and is particularly challenging when used in scenes with non-linear horizons (mountains) or when vertical objects such as trees or buildings get in the way. These filters and their application in landscape photography was invented in the 1970s by the late master Galen Rowell. Some photographers useВ plastic or glass GND filters to expose for the shadows of an image that also has bright areas, placing the filter in front of their cameraвЂ™s lens to diminish the portion of the image with bright highlights вЂ“ typically the upper half. There are three ways to overcome the cameraвЂ™s limited dynamic range: Graduated Neutral Density (GND) Filters Given that limitation, what can we do with todayвЂ™s modern cameras to go about increasing dynamic range in our photographs and achieve a High Dynamic Range, or HDR, image? Some of the newly-manufactured cinema cameras, like the Red Weapon, are beginning to push above 16 stops and closer to the 18-stop range.

In fact, the human eye can see about 20 stops (EV) of dark/light difference, whereas the best modern digital SLR camera CMOS sensors currently on the market can see around 14-16 (such as the Nikon D810 at base ISO 32 or the Sony a7SII/ a7RII). When facing a vivid, colorful sunset, humans can easily see both pretty colors in the clouds as well as details in the backlit shadowy foreground вЂ“ a very wide dynamic range. The limited dynamic range of cameras compared to our own vision can be extremely frustrating to landscape photographers, many of whom (myself included) strive to capture a natural scene with as much fidelity to reality as possible вЂ“ we want to create photographs that match what we see in our mindвЂ™s eye. This limitation is a factor of an imaging deviceвЂ™s вЂњdynamic rangeвЂќ, which refers to the gap in luminosity between the lightest and darkest parts of an image. Have you ever noticed when photographing a sunrise or a sunset that your DSLR camera canвЂ™t capture the brightest and darkest part of the scene at the same time in one exposure? That youвЂ™re forced to choose a single exposure thatвЂ™s correct for one but not the other?
