What is dynamic range?

Earlier learning about HDR, y'all should take some time to understand what dynamic range is. The Oxford Lexicon defines dynamic range every bit "the ratio of the largest to the smallest intensity of sound that can be reliably transmitted or reproduced by a particular sound arrangement." That definition refers to audio, but the idea is similar in photography. Dynamic range relates to how much data a camera can capture at the extremes of exposure in a scene, from the darkest to the lightest parts of a photo.

What is HDR?

HDR stands for "high dynamic range." It is a technique used by photographers to balance light levels in a scene. It is commonly used in situations where there are significant differences in exposure within a single frame. A typical example of such situations is when indoors, shooting through a window to an area with direct sunlight. In this case, a camera will either under-expose the room or over-betrayal the outside.

We will talk about the technique afterward in the postal service, but the gist is that a lensman needs to take multiple shots at different exposure levels. Some need to be darker then that the highlights are brought down, while some pictures demand to be brighter to bring out detail in the dark. These images are and so merged with specialized software, which will get all possible detail and put it together in a single paradigm with a more balanced exposure across the spectrum.

HDR photos are made by merging multiple images taken at unlike exposure levels. Some phones have been known to cheat the process by shooting one image, duplicating it, editing exposure, and merging different versions of the same photo. This essentially works, just only to a sure extent. Over-editing an image can bring out dissonance and other unwanted elements.

Besides: The all-time camera phones bachelor

Other phones accept advantage of multiple cameras to take the same photo in multiple exposure levels. This is considered true HDR, but somehow the software has difficulty getting highlights and shadows correct.

Manufacturers set upwards their cameras and algorithms differently, so we tin't pinpoint the upshot, just so far, no phone has convinced us of their automatic HDR implementation. Here is a sample of the divergence between automated HDR and true HDR. All were shot using the same telephone (Moto E5 Plus) for a post where we showcase what a professional lensman can exercise with a inexpensive smartphone camera.

Shooting your images:

Pick your scene, set the tripod/camera, compose the image. Keep the camera withal for the whole duration of the shoot.
Lock your focus where you want information technology. You don't want images with different focus points.
Detect the correct exposure settings for your main subject. If in that location isn't a unmarried field of study, or it's too large, balance exposure as much as you can.
You lot volition change cypher but shutter speed from now on.
Take the first prototype.
Change the shutter speed to make the image darker than the commencement image by one f cease (larn more than virtually stops here) and accept some other photo.
Repeat step six until you expose the brightest point in the image correctly.
Change the shutter speed to make the image brighter than the first image by one f terminate and accept another photograph.
Echo step 8 until you expose the darkest point in the image correctly.

You may wonder why I am non giving you a specific number of photos to shoot, which yous see in most HDR tutorials. Many claim to accept some magic number of pictures you lot need to shoot, but the truth is HDR photography doesn't work that way.

How many photos you demand to shoot depends on your scene, equipment, the subject, light evaluation skills, and editing mode. Depending on the situation, you tin can skip multiple f stops betwixt exposures, just those are lessons for another solar day. Today we give yous a general guide to capturing all detail beyond the spectrum; from the darkest to the brightest points in your photo, also as everything in between.

Merging your photos:

You will need to notice software that can merge bracketed photos into a single HDR image. Some pop ones include Lightroom and Photoshop. More advanced users can go programs similar Aurora HDR and Photomatix Pro. There aren't many costless alternatives, but a expert one is Luminance HDR.

The steps for merging a photograph are slightly different from each program, so we can't give you step-past-step directions. The idea should be similar beyond the lath, though. Option your images, tell the software to merge them, and edit to personalize the prototype.
