High Dynamic Range (HDR) Photography Workshop
Saturday November 19, 2011
HDR photography is short for High Dynamic Range, one of the constant issues with photography has always been the limitation of the camera and printer to show as scene as we can see it with our eyes. HDR is a set of techniques that allow a greater dynamic range of luminance between the lightest and darkest areas of an image than standard digital imaging techniques or photographic methods. This wider dynamic range allows HDR images to represent more accurately the wide range of intensity levels found in real scenes ranging from direct sunlight to faint starlight.
By merging multiple photographs, and then using tone mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, we can produce images with preserved or exaggerated local contrast for artistic effect.
Any camera that allows manual over- or under-exposure of a photo can be used to create HDR images.
This class will show you how to set your camera to capture the full exposure range, and then how to combine the images using special HDR software.
The example below shows the three images used to make the HDR image, which is a more accurate representation of what we would see.


We will start by going over the settings to get proper exposures to combine for the HDR image. We will then go out in the field and capture images to work with in the second part of the class. We will then combine the images using Photomatix software and learn the different methods and effects that can be created.
Upon registration you will receive a discount code of 20% on Photomatix software.

Night Photos – Fort Chaffee Abandoned Hospital – Photo Backstory

Night photo from the Hospital located at Fort Chaffee Arkansas, which has been abandoned for many years.
As part of my weekend long Night Photography Workshop last weekend, we did a night photo shoot at the abandoned hospital at Fort Chaffee.
The medical complex at Fort Chaffee opened on December 7, 1941 (Pearl Harbor Day). The medical complex itself is an enormous site with 128 buildings all held together by long hallways. The complex has its own exchange and theater. It even had its own four lane bowling alley, not to mention being a 1,595 bed hospital.
Since the hospital is abandoned there is no electricity, no lights, and everything is very dark. This means that we had to supply the lights. For these photos we placed a lantern inside the buildings to light the inside and allow the light to shine out from the broken out windows, bringing life back into the building.
To light the outside a technique called “light painting” was used. A shutter speed of 2 to 30 seconds was set and then the outside of the buildings was painted with light from a flashlight. The technique involves moving the light constantly so not to have any hot spots and to be able to direct the light to only the areas that you wish to have show in the photo. Trial and error is the only way to work out the correct exposure and amount of light painting needed, and each photo will be a unique work of art.

Kansas Dust Storm – Cimarron National Grassland
The Dirty Thirties
A dust storm at Point of Rocks, in the Cimarron National Grassland, near Elkhart Kansas, serves as a reminder of the Dust Bowl or the Dirty Thirties.
Years of cattle grazing and farming, followed by a drought, degraded the soils and made them unproductive. By the 1930s many acres were barren. The strong winds that blow across the prairie swept up the loose soil, creating huge dust and sand storms. This area was part of the Dust Bowl, an area that covered parts of Kansas, Oklahoma, and Texas, named for the great dust storms. Morton County, where part of Cimarron National Grassland is, was one of the most devastated areas.

The U.S. government wanted to stabilize the soil so the land could be used again for agriculture. Healthy grasslands reduce soil erosion and water runoff and provide a dependable supply of summer forage for livestock and wildlife. The U.S. Congress approved the Bankhead-Jones Farm Tenant Act in 1937, allowing the government to buy some of this unproductive land with loose soil.
The land was first administered by the U.S. Soil Conservation Service and in 1954 was turned over to the U.S. Department of Agriculture Forest Service. The former Point of Rocks Ranch became Cimarron National Grassland in 1960. It is the largest tract of public land in Kansas.
