HDR vs Exposure Fusion

First try to understand what these two techniques:

• L ' HDR stands for High Dynamic Range, is a technique used in computer graphics and in photography so that the lighting calculations can be done in a larger space (just a high range) and can represent values \u200b\u200bof very high or very low lighting. HDR techniques are based on the physical nature of light. For calculations using the same unit of photometry, where, for example, in the sun is assigned a brightness value millions of times greater than that of the personal computer monitor. The HDR makes it possible to capture a scene and then having total control on the final image, for example, you can display the picture again, correcting or improving the outcome. © wikipedia

• Exposure Fusion is a technique from a series of photos it produces a new set by taking the parts correctly. At first glance it might seem a kind of HDR, but does not need to create a mid-term and make the tone mapping. The algorithm selects pixels of different images based on saturation, contrast and brightness. Compared to this kind of photos hdr photos is much faster to build and has fewer problems with halos around objects typical of HDR photos. Especially this last point allows for more realistic and natural picture. © www.clickblog.it

to achieve a shot with this technique you must use the bracketing of our camera, allowing for three shots with different exposures: normal exposure, overexposed and underexposed. Logically, you should use a tripod, a remote control (or lack the self-timer delay) and if you can lock the mirror reflex to avoid small vibrations.

In our case, here are three shots of the last flowering Orchid:

Ora utilizzando photoshop (file -> automatizza) si può creare la foto in HDR:

Exposure While the Fusion we can use some ad hoc software, as in our case Photomatrix.

As you can see the two photos are quite different, I personally find it after shooting with photomatrix product (Exposure Fusion) more real with richer colors and close to reality, while in the shooting HDR images look quasi eteree.

Voi che ne pensate? quale preferite?

La macchina fotografica è uno strumento semplice, anche il più stupido può usarla, la sfida consiste nel creare attraverso di essa quella combinazione tra verità e bellezza chiamata arte.
