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.

Learn Digital Photography Class Starting July 26, 2011

New Session Starting July 26, 2011

This is a six week, 2 1/2 hour per week of classroom instruction and a location shoot. The course is designed for the beginner to novice photographer with a DSLR camera. The course is not intended for film photographers, although much of the photographic technique is the same, a great deal of the content will only apply to digital.
There are only three things that control exposure, the ISO speed of your film or camera, the Aperture (the size of the lens opening), and the shutter speed (how long the lens is open). This class will show you how, using “Liquid Light” , these three things interact to give control of the exposure and therefore the final image’s impact.
Once you understand exposure you can use it to create many photographic effects, including motion blur, freezing the subject, blurred backgrounds, and depth of field. You will learn that the camera is your enemy when shooting on “Program or Auto” and that you must take control away from the camera and turn it over to your creative vision. You will learn how to use your digital camera’s tools, such as the ”exposure meter” and “histogram” to give you the control over exposure needed for “fantastic” (not just properly) exposed photos.
You will learn to use composition techniques such as: the Rule of Thirds, Leading Lines, S curves, C curves, Light, and many others to add interest to your images. Today’s digital camera can do an excellent job of getting a good exposure, but creating the image is entirely up to the photographer.
You will learn about equipment, including lens, flash, tripods, cases, and many of the specialty gadgets that are available.
Once you have taken the image you must process it before it can reach the full potential, we will cover how to download, organize and backup your image library. We will learn about the benefits of shooting RAW files verses JPEG or TIF and how to do basic editing using Adobe Camera RAW (ACR) or Adobe Lightroom.
There will be homework assignments, and in class reviews by both the instructor and the other class participants.
Just over halfway through the class we will do an in field photo shoot, to apply what you have learned about capturing the image and then use these images to complete the image processing part of the class.

Night Photos – Fort Chaffee Abandoned Hospital – Photo Backstory

Night photo fromtThe Hospital located at Fort Chaffee Arkansas, which has been abandoned for many years. 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. (Greg Disch)

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

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. (Greg Disch)
