Although these programs operate differently and have different things you can adjust in your final blend, the basic idea of both is to produce a final image that has a high dynamic range with good detail in both the shadow and highlight areas. The program reads the files to be blended and creates a composite that hopefully pulls from the best part of each of the images. The result is a well-balanced, bright image with details in the highlights and shadows.

The biggest boost that bracketed images provide is the ability to have detail in the shadow areas of images without needing a lot of extra lighting. Typically, brackets are shot using only available light, a method that often creates lots of deep shadows and bright highlights if only one frame is being used. Another thing that becomes possible, is masking a darker exposure into the blended image in order to get a better window view.

If you want a really great window view, try shooting an extra shot exposed for the view with a flash pointed directly at the windows to make for easier blending. An extra flash shot can also be blended with the HDR bracket on color blend mode in order to get better overall colors.

Again, we want to cover the range of shadows to highlights, so one image should be exposed for the darks, one for the midtones, and one for the brights. Is nine exposures overkill? Like with lower exposure counts, we still want images that capture detail in the shadows, midtones, and highlights. The difference now is that we can cover a lot more ground with nine total exposures. We can have three different levels of exposures for shadow detail, three for midtones, and three for highlights, ensuring we can cover a wider range while also hitting every step in between.

Well, from our tests, one exposure can get the job done for a quick and dirty HDR effect. At a quick glance, the single-exposure and nine-exposure images look very similar. The nine-exposures does have little more information in the highlights and shadows, but when both are viewed zoomed out, the differences are slight. But if you want to take that merged image and continue editing, making further adjustments to exposure and color, then the single-exposure HDR starts to fall apart.

Here we compared the nine-exposure and the single-exposure side-by-side after making boosting the highlights on both. The nine-exposure HDR provides near perfect detail throughout the highlights and shadows while avoiding the unacceptable noise issues of the single-exposure HDR.

The three-exposure HDR is much closer, and three exposures is likely the right number for most people most of the time. This especially true when you go to add additional edits after the HDR has been merged. Today we find out! What is HDR? Well, something like this: This image is exposed for the highlights, meaning we can see detail and colors clearly in the bright areas, but the shadows are dark and hard to make out.

What's the optimal number of shots to produce a high dynamic range Does it vary from scene to scene? Do the capabilities or limitations of my camera factor in? Are there different HDR techniques better suited to more or fewer individual frames? What are the advantages and disadvantages of using a greater or smaller number? Improve this question. I love their tools viveza, silver efex pro , and at first glance, this seems to be another potentially great product: niksoftware.

Later I discovered that 3 shots were more than enough. Add a comment. Active Oldest Votes. Improve this answer. Drew 2, 2 2 gold badges 21 21 silver badges 34 34 bronze badges. That waterfall shot is beautiful — Sam Saffron. Nice to see good photo-realistic use of HDR. Indeed, it is refreshing indeed a not exaggerated performance of HDR!

Thank you. Yeah, I dropped my flickr account. Those images aren't currently online, but I flagged this into my Todo file to figure out. I actually just use the free command line "Enfuse" tool myself. There are some GUI wrappers for it, and I've worked a little bit on my own wrapper. For the most part, default settings work well enough, although when it comes time to tweak those settings, it can be a little tedious.

It's not really high dynamic range imaging if you only use one shot. There are plenty of scenes you could shoot whose dynamic range far exceeds what your camera is capable of capturing! One way or another, your picking and choosing where to keep levels and where to discard them In the case of a scene with twice as much DR as a camera is capable of say stops when a camera can capture , sure I can't deny that.
