When you take a photography course online, you can learn a lot of details about the profession of photography. Courses take you through the basics as well as help you develop your Photoshop skills and skills in infrared photography. Infrared photography, also called IR photography, offers the photographer the chance to see the world of the “unseen.”
An “Unseen” World Made Visible
That is because the human eye cannot see IR light, which is a light that lies beyond what is considered the visible spectrum. So, when images are taken using IR cameras, the resulting pictures look vastly different than what most people see.
As a result, textures, colors, plants, and human skin, or any object that reflects IR light portrays the world in a new and surreal way. Even photography online courses, such as courses on Photoshop, cannot mimic what can be done with IR photography.
That is why photography instructors who teach photography online courses suggest that students take a course in IR photography. As cameras and technologies continue to improve, IR photography will offer a number of opportunities for photographers and artists to broaden into new areas and distinguish their offerings from those of other creative professionals.
Thermal Imaging Technology
The infrared light spectrum, which features a range of light spanning from 700 to 1200 nanometers, is related to thermal imaging. Thermal imaging became popular when it was introduced in movie thrillers. The technology enables the detection of a human being at night by his or her body heat. While digital camera sensors today cannot pick up thermal images, the technology does explain the relationship of IR and photography.
Therefore, photography online courses often acquaint the student with the history of IR photography, which started in the early part of the 1900s. During the Second World War, IR photographs proved to be exceptionally useful. That is because images using IR were not affected as much by atmospheric haze. The images showed distinct outlines of buildings and vegetation, which helped soldiers identify potential enemy installations or targets such as hidden munitions factories and similar sites. They could also detect waterways, lakes, and streams with greater ease.
How the Technology Evolved
During the 1930s and 1940s, infrared-sensitive films were introduced in Hollywood. The military also extended the use of IR photography. Later, during the 1960s, the imaging was popularized by such rock artists as Jimi Hendrix and the Grateful Dead, both of whom used the imaging on their album covers.
As IR technology progressed, it increasingly became used in forensic science. Law enforcement officials depend on IR photography to detect evidence that cannot be discerned readily by a person’s normal vision. When photography online courses offer the topic, students are able to see how the reflected IR light can be used in a creative display. For example, the skin takes on a smooth and milky texture while the veins close to the skin’s surface tend to take on a kind of ghoulish appearance.
IR photography turns out images where the eyes appear ghostly, with the iris of each eye conveying darkish tones. The whites of the eye, on the other hand, take on a grayish appearance. The photography can make black clothing appear white or gray and deepen blue skies with a dramatic tint.
A Fascinating Pursuit
When you learn some of the techniques involved in IR photography, you will also note that the contrast of the photos is different. The pictures take on a crispness that is not noted in regular photography. While black and white pictures come the closest to this kind of effect, they still do not have the same appearance as IR images. As a result, working in this medium provides plenty of magical moments in the field of photography. Gaining an education in this genre can indeed be fascinating.
IR photography covers various options for experimentation. For example, 35mm IR film can be purchased at a low cost. You can use the film easily in an existing SLR. Another option involves the purchase of a circular IR filter that attaches to the front of a camera’s lens. The filter prevents any visible light from passing through to the camera’s sensor.
Needless to say, this type of information can only pique one’s interest in photography online courses. See what is offered online today and learn more about the newest in photographic technologies.
