HISTORY BUFFS WHO HAVE EXHAUSTIVELY RESEARCHED THE HELLISH ANIMOSITY OF THE AMERICAN CIVIL WAR, a conflict which sowed seeds of resentment that bear bitter fruit to this very day, may have some small grasp of the vitriolic divide between those who espouse High Dynamic Range (HDR) photography and those who believe its practitioners are in league with Beelzebub. Pro-HDR factions believe those who resist this magical art should be forced to declare themselves Amish on the spot, while the opposite camp believes that all cameras that shoot HDR should be pulverized and used as landfill in Hades. We’re talking irreconcilable differences here.
When HDR first came to my attention, I welcomed it, as many others did, as a way to get around a long-standing problem in exposure….how to modulate between blackout and whiteout in extremely contrasty situations in which a single exposure would either blow out the sky through the window or bury the corners of an interior in blackness. My first attempts with it were exciting, as I tried to shoot frames bracketed across a three or five shot range of exposures, then smooth out the drastic differences between light and dark in the final image. The idea of using HDR for a sci-fi look or a painterly effect never appealed to me. I was really trying to use it to make my pictures replicate more closely the adjustment between light and dark that the eye makes instantaneously.
Over the last five years, however, as I review images I’ve made with HDR software. First, I use the program less with each passing year, and second, I no longer use it to retrieve “lost” tones in dark or light areas of an image. The program I have used since day one, Photomatix, has two main choices, Detail Enhancement and Tonal Compression, and, at first, I worked almost exclusively with the former. For wood grain, stone texture, botanical detail and cloud contrast, it’s remarkably effective. However, it’s also easy to produce images which are too dark overall, and accentuate noise in the individual images. Overcook it even a little and it looks like a finger painting done with hot lava. It thus actually works against the original “looks more like reality” objective.
On the other hand, producing the blended image in the Tonal Compression mode retains most of the sharp detail you get in Detail Enhancement without the gooey consistency. It has fewer attenuating controls, but as I go along, I find I am using it more because it simply calls less attention to itself. In either mode, I have made a conscious effort to throttle the heck back and under-process as much as I can. I’m just getting sick of shots that announce “hey, here comes an HDR photo!” two blocks ahead of its arrival.
I’m also in the middle of a back-to-basics phase based on getting things right, in-camera, in a single frame, and learning to be more accepting of dark and light patches rather than artificially mixed goose-ups of rebalanced tones. Anyway, as of this posting, I’ve taken down the original selection of images that was in the HDR gallery tab at the top of this page and loaded in a new batch that, while certainly not a “final” word on anything, shows, I think, that I’m still wrestling with the problem of how best to use this technology. Give them a look if you can, and let me know your thoughts on the use of HDR in your own work. We all have to figure out our own way to be home, home on “the range”.

ONE OF THE MOST FREEING PARTS OF PICTURE MAKING IS RELEASING YOURSELF FROM THE RIGIDITY OF REALITY. Wait. What is he babbling about? Don’t photographers specialize in reality?
Well, yeah, the photographers who work at the DMV, the city jail and immigration do. Also the guy in Wal-mart HR who made your first employee badge. Other than that, everyone is pretty much rendering the world the way they see it right this minute, with more revisions or re-thinks coming tomorrow. And beyond.
Color processing, once the sole domain of the “photo finishers” has now been taken back in-house by pretty much everyone, and, even before you snap the shutter, there are fat stacks of options you can exercise to recast the world in your own image.
The practice of bracketing shots has made a bit of a comeback since the advent of High Dynamic Range, or HDR processing. You know the drill: shoot any number of shots of the same subject with varying exposure times, then blend them together. But bracketing has been a “best practice” among shooters for decades, especially in the days of film, where you took a variety of exposures of the same scene so you had coverage, or the increased chance that at least one of the frames was The One. Today, it still makes sense to give yourself a series of color choices by the simple act of taking multiple shots with varying white balances. You can already adjust WB to compensate for the color variances of brilliant sun, incandescent bulbs, tube lights, or shade for a more “natural” look. But using white balance settings counter-intuitively, that is, against “nature”, can give your shots a variety of tonal shifts that can be dramatic in their own right.
In the image above, the normal color balance of the gallery entrance would have rendered the bust off-white and the outer vestibule a light grey. Shooting on a tungsten setting when the prevailing light was incandescent gave the interior room a creamy orange look and amped the vestibule into deep blue, setting the two areas sharply off against each other and creating a kind of “end of day” aspect. I shot this scene with about five different white balances and kept the one I liked. Best of all, a comparison of all my choices could be reviewed in a minute and finished by the time the shutter clicked. Holy instant gratification, Batman.
