What Exactly Is HDR Photography?

Photography, which was once a passion of people, is now a full time profession of many. To help professionals bring out the best effect, several new technologies have been introduced in this field. With modern cameras and advanced equipments, photographers can now capture every angle with complete perfection. One of the latest technologies, which have taken photography to new heights, is High Dynamic Range or HDR photography.

What is High Dynamic Range or HDR Photography?

Before proceeding to HDR, it will be ideal to recapitulate dynamic range in a line. Dynamic range refers to the difference between darkest and lightest color value of a photograph or the photo contrast. High Dynamic Range is a technical jargon used in the field of photography to denote the photographs, which have the maximum dynamic range. HDR images have more dynamic range compared to the ordinary digital cameras and produces high quality photographs.

HDR photography is a new concept and many of you may not have a clear idea about it. You need to know that HDR photographs are not unnecessarily colorful or unrealistically artistic. The purpose of using this technology is to increase the dynamic range, produce clear photographs by overcoming the restrictions of ordinary camera features. With this technique, one can compile three or more photographs snapped at different exposures and create a beautiful final product.

Advantages of High Dynamic Range or HDR Photography

Nowadays, HDR photography has become a popular choice. If you are new to the field of photography, glancing through the advantages of HDR photography is worth it.

With HDR technology, photographers can compile different photographs taken at variable exposures. Not only that but also this technique allows photographers create images with an excellent light detail, which is not possible in single shot taken by ordinary cameras. By using HDR cameras, photographers can capture excellent still photographs, in overexposed as well as underexposed settings. Though photographers have the freedom of adding several effects to the photographs, it is always recommended to keep the image as realistic as possible.
Photography is an art and someone with best creative skills can flourish in this field. However, to cover up the lack of creative ideas, one can use HDR technology. Though this is not a common practice, at times one can really make some impressive art by using this technology. Yet, to capture the perfect angle, one should carry a tripod. One also needs to have the right photo editing software for editing the photograph and adding the required special effects.

Where To Learn HDR Photography?

Nowadays, there are several institutions offering professional HDR photography courses. One can enroll in any of the reputed institutions to learn HDR photography in complete details. It is also recommended to attend different photography workshops to increase the knowledge base on this type of photography. Regularly updating yourself about the latest introductions in this field can also be of great help in developing your skills and become an established photographer.

What Exactly Is Infrared Photography?

Infrared photography or IR photography has offered a complete new dimension to this field. Nowadays, many professional photographers are using infrared to create a completely different effect in a simple photograph. IR photography is completely different from any other types of photography and it requires special films for capturing the light effect needed for using this technology.

At A Glance

Infrared photography refers to a special type of photography, which uses films, which have infrared light sensitivity. By using infrared lights in a photograph one can bring special effects like false colors in a simple portrait.

When you are learning about the basics of infrared photography, you should also note that this type of photographs have the ability of penetrating light fog and haze in a successful way, to bring out a clear image. The wavelength of these photographs is also longer compared to visible light, which helps in obtaining a clearer image in spite of the pollution or dusts present in the air. Another major advantage of using infrared rays is it never produces any false color in black and white image until photographer selects the option of doing so. Though the use of IR technology has remained vital for black and white photography, it has become almost obsolete for color photography.

Different Types of Infrared Photography

Infrared photography has evolved greatly with time. Several new developments have taken place in this field and taking a glance through the different types of infrared photography is worth.

Analog:

Analog IR photography refers to the sub-division of infrared photography, which requires films that have stray light sensitivity. Someone who wants to practice Analog IR photography needs to use MACO IR820C or Kodak HIE Infrared films for the work, as these two films only offer sensitivity to stray lights. Before taking a snap, one should also ensure that mechanical frame counter is there in the camera.

Digital:

This is considered to be more popular than the Analog IR photography. Cameras, which are meant for digital IR photography comes with sensors that are highly sensitive to the infrared radiations. Sometimes, these cameras come with "IR Cut-off Filter" or "Hot Mirror" for blocking radiations, which can affect the image.

Applications

Though digital photography and HDR photography is now ruling the market, one cannot ignore the importance of infrared photography. For some applications, infrared photography is still considered to be the best choice.

One of the most important applications of infrared photography is taking snaps in a dark room.Capturing wildlife at nighttime in complete darkness.Create a chalky appearance on the photograph by using IR photography in outdoors or indoors with the availability of clear lights.Capturing images during the state of war, where light availability is reduced during the night time.

There are several advantages of IR photography. You may read different books on the subject or visit photography forums to know more.
