![]() ![]() By combining images taken at different exposures, you can meet or even surpass the range seen by the human eye. So why use a single image? This was the heart of the question posed by the pioneers behind HDR imaging. Digital photography is a constant game of juggling tradeoffs and it's literally impossible with the current consumer-grade technology to capture the full range of detail that you see before you with a single image. Similarly, if you adjust your exposure for a sunny day, most or all of the detail present in a shadow will be completely lost. If you set the exposure settings so that the details in a dark room are clearly shown, any points of light present in the image will be completely blown out. As you well know, it struggles with both shadows and highlights. ![]() Your camera, by contrast, isn't quite so gifted. ![]() In other words, your "range" of perception is quite broad. What this technical babble means on a practical level is that you possess the amazing ability to see well on a dark night, a bright sunny day and everything in between. The best of these sensors have dynamic ranges of about 13.5 stops of light, while human eyes are closer to 18-24 stops. Your eyes have a much higher dynamic range than most or all commercial electronic sensors. One of the most limiting of these factors is dynamic range, which, loosely defined, refers to the scope of lighting conditions in which we are able to perceive the world around us. There are several reasons for this: the fact that you have two eyes and one camera lens, different focusing mechanisms, etc. There are plenty of tutorials out there that explain how to merge them together.Have you ever wondered why you can't really shoot what you see? No matter what camera you have, from a cheap cell phone to a 5D, the images that are produced are notably different than what you're perceiving in the real world. This step depends on which photo editing tool you are using. Load all the images into your photo editing software and put all the different photographs together.This will give you a total of five images varying in brightness. Step four is to do the same thing as steps one and two but this time you are going to overexpose two and four stops.The third step is to take a regular photograph, meaning you’re not going to under -or overexpose.Once you have your first photograph you are going to want to do the same but this time you’re going to underexpose 2 stops.The next thing you want to do is change your exposure settings. Choose a subject you want to photograph and set up the tripod and focus in with your camera.Here are the very basic steps to capture a 5 shot HDR image. Next you’re going to learn how to make HDR images. This allows you to take a couple of different photographs without messing up your frame or shot. It doesn’t have to be a reflex camera any camera will do, but you have to be able to change the settings. A camera that enables you to change the settings manually, preferably a camera that can be set to capture bracketed photos automatically.To create a HDR you are going to merge three to five different images to create a single HDR. Unlike the human eye, a camera can’t capture that great a difference of contrast in one moment. A high dynamic range image is an image that has a greater dynamic range of luminance and it allows you to portray a greater amount of contrast in one image. ![]()
