What is HDR? An HDR Definition
High Dynamic Range (HDR) photography produces an image with a broader range of tonal detail than would normally be produced by a single image from your average camera. In this journal we are going to discuss exactly what is HDR and what types of scenes have a high dynamic range to begin with.
For example, take a moment and look at the room around you. Most likely, you will see a room with bright highlights where you have lighting (be it a window or tungsten light) and you will also see dark shadows where the light isn’t falling. However, our eyes can generally see the entire dynamic range within a scene like this. Meaning, you can see details in the shadows and simultaneously see the detail in the highlights. Take a moment and walk outside, after your eyes adjust, you can once again see all the detail in the shadows and the highlights (even when looking in the direction of the sun).
However, in these same scenes, the average camera is only going to see a portion of that 20 stop range. For example, if your camera has a dynamic range of 10 stops, then the camera will see half of the range that your eyes would see. Let’s relate this to our examples. If you are inside, and you are trying to see the detail in the shadow areas of your room, your camera is going to reach a limit where everything brighter than that 10 stop range will be completely blown out. Likewise, stepping outside, if you wanted to capture the detail in the clouds and bright sky, the camera will not be able to show detail in the darker shadows that are below the horizon line.
I am sure you have all had the experience of trying to take a portrait of a friend standing in front of a beautiful sunset. Remember how that shot always turns out? Either your friend is nice and bright, an the sky behind him/her goes completely white, or the sky looks amazing and colorful and your friend is pitch black.
Let’s show you a real world examples shot from Canon EOS 5D Mark III. In this first image, we can see all of the detail in the clouds in the sky, but notice how everything below the horizon line that is in the shade is almost completely clipped.
In this second example, we have gone 4 stops brighter to show detail below the horizon, but now look at how most everything in the sky is blown.
This is the limitation of our camera’s dynamic range in comparison to our eyes. Again, the goal of HDR photography is to broaden that range by using several techniques (bracketing, single-shot HDR, etc). But, to give you a little taste, here is an example of the final HDR shot that we created from this scene.
Let's see some examples of your HDR photography! Post some links and/or thumbnails below.

What is HDR? An HDR Definition
High Dynamic Range (HDR) photography produces an image with a broader range of tonal detail than would normally be produced by a single image from your average camera. In this journal we are going to discuss exactly what is HDR and what types of scenes have a high dynamic range to begin with. What is Dynamic Range?
Dynamic range simply refers to the range of light in a scene from the darkest shadows to the brightest highlights. A scene that has a high dynamic range simply means that there is an extremely broad range from the darkest shadow to the brightest highlight. The problem with cameras is that their dynamic range is fairly limited (at least when compared to our eyes). This means that if you are able to see detail in the shadows, then your highlights are typically completely white or “blown out.” Vice-versa, if you can see details in the highlights, generally the shadows become fully blackened or “clipped.” The goal of an HDR photograph is to capture more of this dynamic range than would not be possible with a single image.Dynamic Range of the Human Eye
The human eye has an incredible dynamic range that is estimated to be around 20 stops. A stop is simply a measurement of light. The dynamic range of the human eye is significantly broader than most DSLR cameras with ranges between 10-14 stops.For example, take a moment and look at the room around you. Most likely, you will see a room with bright highlights where you have lighting (be it a window or tungsten light) and you will also see dark shadows where the light isn’t falling. However, our eyes can generally see the entire dynamic range within a scene like this. Meaning, you can see details in the shadows and simultaneously see the detail in the highlights. Take a moment and walk outside, after your eyes adjust, you can once again see all the detail in the shadows and the highlights (even when looking in the direction of the sun).

All Cameras Are Not Equal
DSLR Cameras that have a broader range are generally more expensive. Sensor technology is getting better and better which allows the latest cameras to have a higher dynamic range. More recently, Nikon is currently the leading brand when it comes to highest dynamic range with the Nikon D800 having a dynamic range of 14.4 EV (Stops), whereas the Canon EOS 5D Mark III has a range of 11.7 EV.What is HDR | Conclusion
HDR photography has the potential to produce images that are closer to what we can see with the naked eye (or beyond if they are processed too far), with crisp detail visible in all ranges of light.Let's see some examples of your HDR photography! Post some links and/or thumbnails below.

When I first started into digital photography about a year and a half ago, HDR photography and post processing really caught my attention. I did a lot of reading and experimenting with various software and have used DeviantArt as my means of showcasing my growth as a digital photographer. In my experiences, I have found that a lot of people get confused between HDR and tonemapping. In software such as Photomatix, the HDR process blends multiple exposures to be able to extend the dynamic range of the scene (like article above). It is possible to continue on in the software to perform tonemapping which allows for adjustments of contrast, colors, levels, etc but most notably you can adjust the blended image to make the image more natural or a bit grittier.
The grittier approach is what most people consider "HDR", which is not true. With Photomatix it is possible to get the same effect using only a single image and selecting "tonemapping". I feel that both a natural and grittier approach have their places and use both frequently to further enhance a scene.
When I want to perform a more natural blend (HDR), I tend to blend in Photomatix, do not perform any tonemapping, save as a floating TIFF, and upload into Lightroom. Some examples of the differences are below:
HDR with tonemapping: jxsnyder.deviantart.com/art/Co…
Just HDR: jxsnyder.deviantart.com/art/Mt…
Some of the defining characteristics of tonemapped images can be: haloing around contrasting areas (sky versus trees), artifacts (the "grit"), and can sometimes be a lack of true shadows/highlights.
