High dynamic range (HDR) photography captivates viewers through its amazing color presentation in landscape photography. This is accomplished through its advanced tone mapping and its dazzling exhibit of shading. Rich and lovely pictures simply explode utilizing HDR strategies and render obsolete the age-old issue of “The camera not having the capacity to record what the eye can see”. HDR conquers this problem and then some.

 

From the days when photography was in its infancy, the days when beginning photographers made glass negatives utilizing a blend of silver nitrate and egg whites, photographic artists whined about not being able to record a scene on film as the eye saw that scene. Numerous professionals figured out how to overcome these restrictions, consider Ansel Adams’ Zone System for high contrast photography. He learned how to control presentation with channels, film affectability, creating procedures, and innovative darkroom tactics. The outcome was, and stays, shocking and filled with symbolism. Both novices and genuine specialists, everyone ended up battling against poor shadow detail and washed out skies. The battle was genuine and not until HDR did that problem find a solution that anyone can use.

The dynamic scope of what the eye can see over the camera range is gigantic. Our eyes have developed to see the whole range from profound shadow to splendid highlight and everything in the middle. Catching that same image on film or utilizing a computerized sensor presents one with a proficiency issue. your film, computerized sensors and the strategies for printing on PC screens, are just not up to the task of catching subtle colors and shadows over a wide element range. HDR photography transformed all that instantly at its inception. Photographers both professional and novice utilizing HDR systems are presently ready to catch light over the most stretched out element ranges without breaking a sweat.

What is this dynamic reach I continue alluding to? In its least difficult terms, the dynamic reach refers to the range in luminance from the brightest to the darkest light values in any given image. High element range photography refers to the capacity to catch light over the most or the greater part of the dynamic scope of the scene being shot. HDR is best utilizedized by shooting from 3 to 7 duplicate exposures over a scope of f-stops and/or screen rates and afterward recombining those exposures into a single blended picture which now reflects exposures made for highlights, midtones and shadows. The results are unbelievable even when using a software such as Photomatix on even a single photo.

Each duplicate picture adding to a completed HDR picture inputs imperative data about the picture being made. Underexposed pictures add to highlight points of interest while overexposed pictures give data about the shadows. Whenever merged into a single image, the sectioned exposures create a HDR record that contains the greater part of the data important to deliver the HDR merge. A second step, regularly alluded to as tone mapping, changes over the HDR image into a usable picture that may then be saved as a TIFF or JPEG document. The tone mapped picture is the one that is most helpful when we print a HDR picture. The tone mapped picture shows the full scope of shading and detail in both the shadow ranges and the highlight zones while holding the midtones genuine and rich.

HDR doesn’t simply happen. This ought to shock no one. No photography, at any rate not great photography, simply happens and HDR is absolutely the same. Well before the individual images are taken. one must have a good understanding for the exposures and other settings of the camera you are using. Knowing how to setup a group of photographs for HDR use, what exposures to shoot, how many photos to shoot and how to reduce movement in the photographs is critical to getting good results. Knowing how to edit pictures on your PC is a help to speeding your work process as you merge and tone map your pictures. An integral knowledge of both your camera and how to shoot HDR goes a long way toward helping you make rich HDR pictures.

Is HDR great? Yes but not in every case. It is fitting for a few yet not all conditions. It is not suitable for all subjects. Actually, most subjects that show a substantial level of movement are by and large not possible to use in HDR photography. Be that as it may, when the conditions and subjects are correct, HDR tackles numerous dynamic reach issues.

This brief intro to HDR is only a lead for our group of HDR tutorials that are beginning next week. We will be addressing the entire process from preparing to shoot the photographs, how to get the best results and how to edit those results. When our multi-part tutorial programs are finished you will have the understanding you need to begin shooting and tone mapping HDR photographs.

Look for our first tutorial “Setting Up Your Camera for HDR” in the next few days.
