Photography is a science and art at once. An expensive camera cannot guarantee great shots, but Aurora HDR can.

With the birth of photography have come several notable research and development being made to constantly improve the quality of captured images. These R&Ds, over the years, account for some of the major breakthroughs that have been recorded since the 19th century; the ones that ushered in the color photography which eventually gave birth to the era of digital photography that we now live in.

As is the case with most breakthroughs and successes, new discoveries having their own peculiar challenges that eventually lead to further successes when handled resourcefully, the early days of digital photography also had its fair share of challenges and limitations. It was soon discovered that, like the film technology, it was still lacking in the quality of images captured with specific reference to exposure.

The light exposure value of an image, also known as its dynamic range value, can be described as the difference between the quality of the photo captured by the lens of a camera and that which our optical eyes see. The ever-evolving state of digital photography notwithstanding, some of the best lenses are still unable to replicate the exact dynamic range that’s comparable to that of the eyes. More precisely, a typical camera is only able to capture an average dynamic range value of about 1:1,024, which is a far cry from that of the human eye’s 1:65,500.

Back in the film-age, this gap was usually bridged in the darkroom. Nowadays, it occurs on the computer by means of some specialized software known as the High Dynamic Range Imaging app. The internet abounds with information about HDR; videos and tutorials. On Aurora HDR web site there is a guide about how to take HDR photos, helping anyone in spite of their skill level to become a pro in the High Dynamic Range photo technology.

HDR and Micro-contrast Explained

Sometimes mistaken for micro-contrast, the High Dynamic Range (HDR) photography is a technique that involves merging and editing images that are captured under different light exposures. A resultant HDR hybrid-image is produced from the merged images. The HDR image is ideally picture-perfect with a dynamic range value that equals, or is near that which our optical eyes can naturally see.

Micro-contrast, on the other hand, involves the process (or series of processes) where the image’s details are improved by adjusting the contrasts in small lines to each other.

While focusing on the definition of HDR technique, it’s important to mention that many of the HDR software packages that are available feature the “micro-contrast” option as well as other photo editing tools for a more picture-perfect finishing or effect.

As earlier mentioned, the need for HDR became necessary as a result of the series of dynamic-range deficiencies encountered even in images captured by very powerful lenses. HDR applications are therefore designed to help come as close as possible to achieving eye-photo-sensor image perfections, and apps like Picturenaut, Aurora HDR and others are great for creating such fantastic HDR results.


Designed in the German photo-community by HDR Labs, Picturenaut is a free-personal Windows HDR app that’s been around for close to a decade now. The app features some ultra-modern tools like exposure detection from EXIF data, image alignment and ghost removal. Its tone mapper has immensely helped photographers and hobbyists create amazing HDR images.
