HDR (High Dynamic Range) is a post processing photo technique which nears the image’s ability to sense as well as a human’s eye. As wonderful as today’s cameras are the film, or the sensor, just cannot handle the same breadth of visible light’s spectrum as our eyes. Photographers in harsh or direct light have to select exposure settings to lose the detail in highlighted areas (i.e., “blow out”) to gain detail in the darker areas or get the highlights right while accepting that the dark areas will go black. HDR solves this with multiple pictures, each with its own exposure–normal, overexposed for dark areas and underexposed for dark areas. Back home the computer application takes the best information form each image and integrates them and–voilá–an image with no loss in detail!

Naturally, like autotune in songs, it can be purposely overdone for artistic effect to get that posterized-like effect. Another decision in HDR post processing is about handling objects in motion during the photographing. Combined they produce partial exposures (i.e., “ghosting”) if kept but the HDR application can eliminate the artifact. In these photos the artifacts were kept since they add the feeling of the wind at the time these photos were taken. Usually it is better to avoid noon time’s too direct sunlight when taking outside photos but the HDR technique allows for this condition–which is handy when the travel schedule doesn’t allow for morning or afternoon image captures.
