[QUOTE="BackdoorArts, post: 334419, member: 9240"] @[URL="http://nikonites.com/member.php?u=13196"]hark[/URL], the thing that these have in common with a lot of HDR photography is the emphasis on texture and structure. High Dynamic Range, in and of itself, isn't really about that, it's about the maximizing of visible light so that you see everything that's there (something your brain does automatically even in harsh lighting conditions) but is not capture-able in that form by a single, "normal" exposure of the camera sensor. What happens, a lot of times, is that when you flatten the light you lose the shadows that help your eye define the boundaries between things, or even within things. To compensate many programs, and photographers, will apply extra "structure" to make these boundaries more visible. This because a defacto [I]style[/I] of HDR early on, and these surreal aspects made many people want to try it, but they are not something that is inherent to HDR photography, they're just a technique that many HDR photographers chose to apply. While my photos are [I]not[/I] HDR (mainly because the conditions do not require it), the B&W luminosity layer I use is often purposefully set so that it flattens the differences in color luminance, so it has a very similar impact. For example, let's take a closer look at this photo... [ATTACH=CONFIG]102297._xfImport[/ATTACH] I've chosen this because it's predominantly composed of blues, reds/browns and shades of grey. Here's the original photo... [ATTACH=CONFIG]102300._xfImport[/ATTACH] There are at least 6 distinct shades of blue within the shot, ranging from very light and pale to deep and dark. When I created the black & white luminance mask, I purposefully looked to use a blue filter so that it would effectively render the blues "invisible" to some level in the B&W shot. As you can see in this screen shot from Silver Efex Pro 2, I have the color filter set on a shade of blue, which comes as close as you can get to squeezing them into the same level on luminance/lightness...

[ATTACH=CONFIG]102310._xfImport[/ATTACH] Applying this as a luminance blend and you can see that the blues have now all shifted to a darker state, some obviously more than others...
