How Many Exposures Do You Need For HDR ?

Condensation X - Prelude

1 exposure - scenes like this won't benefit from HDR

Incubation II

3 exposures - scenes like this may be made with 1 exposure but benefit from more

Antarctica CXXX

5 exposures - scenes like this require HDR

How many exposures do you need for HDR images?

It depends.

It depends on the contrast ratio of the scene you’re photographing.

Ideally, you’d make one exposure per stop of dynamic range in the scene. In your first exposure place the shadows in the top stop of the histogram (to the right), without clipping. Then in subsequent exposures reduce exposure in one stop increments, making a new exposure each time, until the highlights are placed in the top stop without any clipping. Then stop. Making more exposures is unnecessary and won’t improve image quality.

HDR imagery is expanding today’s photographic aesthetics. Identifying the characteristics of contemporary HDR images will help classicists and pioneers alike. The basic ingredients are desirable for both sensibilities, but in varying combinations and to different degrees.
Pronounced Shadow and Highlight Detail
Preserving significant amounts of shadow and highlight detail even in images containing extreme contrast ranges is something long sought after and continually improving in photography. Prior limitations in the medium have established a conventional appearance for photographs than now needs to be reconsidered, first in light of the way the eye sees at a glance, second in light of the way the eye sees adaptively over time, and third in light of the way we might like to represent a scene expressively. Excessive recovery can alter large-scale contrast ratios unnaturally and in extreme cases may yield localized solarization.
Accentuated Edge Contrast
In an effort to preserve midtone separation after extreme dynamic range compression edge contrast is accentuated. This produces dark lines and bright halos, typically feathered rather than hard edged. As they intensify they begin to drive images away from a classic smooth continuous tone appearance.

HDR Without Bracketing
If you need to make an image of a relatively high contrast scene that challenges but does not exceed the dynamic range of your camera (or film), consider double processing. Make two derivative files from one original, one dark and one light. Layer the two together. And blend the best information from each. This practice can substantially improve the quality of the information in your file. Even small changes can make a big difference. Remember, this technique is for challenging files, not for every file. If you can achieve ideal results with Raw processing alone or one layer only - do. Keep it simple, when you can.

Creative Detail Enhancement with HDR Software

 
HDR software is most typically used to render shadow and highlight detail, but it can also be used to enhance tonal separation and detail in any range of tones, even in images with extremely low contrast. The very same tools that are used to compensate for HDR side effects can be used to sharpen any image.
When multiple bracketed exposures are merged into a single processed file, shadows and highlights that exceed the dynamic range of a camera’s sensor are compressed into the dynamic range of a digital file, taking the midtones with them. Depending on the HDR software used, a variety of tools are available to restore contrast and separation in midtones. If used aggressively, these tools produce the tell tale signs of contemporary or grunge HDR artifacts – halos and texture accentuation. These are the very same artifacts that digital sharpening routines use more conservatively to make images appear sharper - only they look different.

If you’re lucky, you may have more than one chance to get things right, but second and third chances, like second and third marriages, can be dicey propositions, and they don’t come with guarantees….
