HDR – High Dynamic Range
I am sure you have happened to have witnessed amazing scenery that embedded into your memory and so you were keen to take a picture of it. But then you were deeply disappointed when you wanted to show the beautiful place to your friends and you saw on the PC screen something that was far away from what you had seen in reality. Although you have a good camera, you still feel something’s missing in your images. They are dull, blurred, colors do not have the right dynamics, and as a whole they make a weary or even “stale” impression. You might ask yourself: where did I go wrong? Note that the fault is neither on your side nor in your camera. It is your brain that’s fooling you. The brain in connection with eyes and the visual cortex does not work like a camera. The eyes supply an enormous number of “images”, but the brain composes the resulting effect from this huge amount of images. Your eyes unconsciously wander around the scene and try to “look” at dark or light parts of the scene. And there we are. Your brain composes the scene from a large number of “images” and thus creates what has remained in your memory. If you want to learn to photograph so as the pictures that you show to your friends are the same as the scenes that you remember, you are at the right place.
What is HDR?
HDR, High Dynamic Range, is a technique aiming at approximating dynamics previously demonstrated on regular basis by the good old color negative. The basis is the so-called exposure bracketing, i.e. taking a series of shots (usually an odd number) with gradually changing exposure. The basis is a “centrally” exposed image, then at least one underexposed image by a value determined by you and at least one overexposed image. A combination of these shots will create “texture” in the light parts and at the same time you will be able to see in the dark/shaded parts.
It is necessary to have a camera that has the bracketing function. Bracketing is the ability of the camera to take at least 3 shots at a time with different shutter speed. If you are looking at the menu of your camera now, seek Autobracketing, bracketing, BRK or numbers -2, 0, +2. If you have a DSLR, your camera most likely has this function. The camera should also be able of taking shots with aperture priority, A setting (A not meaning amateur!!!). It is better to have manual focus setting, but it is not a must. The camera should also have the option of manual ISO setting and RAW imaging and a fast memory card. And where you can no longer make slow-speed exposures “off hand”, you will need a tripod.
