If you struggle with taking a photo where one part is too bright or too dark, try using HDR photography. This technique combines multiple exposures and can help you create a balanced photo. Start by learning the basics of HDR and how it can improve your images.
HDR photography is a process where many photos of the same scene are taken using different exposures and then combined into a single image or edited to fix exposure issues. Photographers use HDR techniques to capture high-contrast scenes such as landscapes and interior shots, where some areas may appear too bright or too dark. This is an image that closely resembles how a human eye would see the scene. To create HDR videos, several images are taken for each frame of the video and are merged into a single video that has a higher dynamic range.
Dynamic range refers to the difference in brightness levels between the darkest and brightest colors that a camera can capture in one shot in photography. The measurement of dynamic range is expressed in stops, with each stop representing a doubling of the amount of brightness captured. Although the human eye can perceive up to 20 stops of dynamic range, image sensor limitations mean that even high-end DSLR and mirrorless cameras are only able to capture around 14 stops. You may have to choose between overexposing the lighter areas of the photo, making them white, or underexposing the darker areas, making them black.
One way that HDR addresses this issue is by using bracketing, which means taking several photos with low dynamic range (LDR) at each exposure level to capture each area separately. Next, the individual images are merged using image-processing software which applies algorithms to adjust the brightness and colour intensity of each pixel. This results in a final image with appropriate exposure settings.
HDR photography techniques can be used whenever you shoot subjects with a wide tonal range with light and dark shadows.
Using HDR photography can assist you in taking pictures of vast and intricate landscapes where every part may need a slightly different exposure, particularly in cases of sunrise or sunset photos and brightly illuminated areas.
HDR can be very helpful when you're taking pictures of rooms with complex lighting, such as when a room has bright windows. If you take a regular photo, the view outside might be perfectly exposed but the inside will be dark. Or, if you expose the interior, the outside view might appear washed out or even completely white. HDR allows you to combine different elements from each photo to create a clearer picture of what the room looks like.
In order to correct overexposed or underexposed areas in a subject or scene, you can use HDR. However, it is important to note that for HDR to be effective, the subject must remain still.
To create HDR photos, you'll require standard photography equipment and photo editing software for processing the photos. When post-processing images, keep in mind that your choice of monitor or display device can impact how you perceive the colors and lighting of the image. Therefore, it's important to consider the monitor you use for editing carefully.

HDR software or photo editing software, such as Photoshop, Adobe Lightroom, or Photomatix Pro, to enhance your shots.
When planning to shoot images for HDR, you need to consider specific settings that will help you combine and edit them effectively later on in post-processing. It is recommended that you use a tripod to avoid camera shake or ghosting while taking photos. Also, be cautious of wind as it can cause movement in subjects like trees or bushes, which can result in blurring of long-exposure shots.
RAW: It is recommended to use the raw image format (also known as RAW) for your photographs. Raw images contain more data compared to JPEG images, and this allows greater flexibility when you use post-processing software to create the final image.
Aperture: To avoid having a varying depth of field in your images, maintain a consistent aperture setting for each shot. You can achieve this by using aperture priority mode to manually select and keep the desired aperture throughout the shoot.
Metering: The metering mode on cameras, also known as camera metering or exposure metering, uses a light sensor to measure light intensity and select the optimal exposure for a photo. On Nikon cameras, you can use the Matrix mode, and on Canon cameras, you can use the Evaluative mode to allow the camera to choose the best exposure for the scene.
You can create realistic digital images with high definition and correct exposure by using common HDR imaging techniques that mimic real-world photos. You can try different strategies and software options to get the desired image. Experiment with adjusting the calibration or exposure time until you achieve your desired result. Certain cameras feature an HDR mode or HDR presets that can combine digital photographs to create high dynamic range images, eliminating the requirement for editing software.
For optimal results, use a tripod to stabilize your camera and adjust the aperture manually to the level you want. Additionally, you can choose the desired exposure time and adjust the metering mode according to your subject. For post-processing purposes, it is recommended that you shoot in Raw to obtain the most image data and information.
Exposure bracketing entails capturing a photo at every available exposure value (EV) on your camera, which is measured in stops. Cameras usually have a setting to take three pictures at three different exposure levels (-2, 0, and +2), which is enough for HDR photography. However, some photographers opt to take up to seven shots at varying exposures. Your camera has an Auto Exposure Bracketing (AEB) mode. In this mode, you can choose the number of images you want to capture and the camera will automatically adjust the exposure for each image.
Please open your preferred image-editing software and proceed to upload the photos. HDR feature is available in several photo-editing programs that can produce HDR images automatically using a series of photos. After the HDR image is generated by the digital imaging software, you can adjust the photo further by using techniques such as tone mapping. This will allow you to brighten low-light areas or darken the brightest areas of the image. Save the HDR image in different file formats and HDR formats used for image encoding, like Radiance RGBE or Open EXR.
HDR photography is an incredibly powerful tool that can help you capture photos with a wide tonal range and light-dark shadows. It's perfect for capturing landscapes, interior real estate shots, and bright or dark subjects - as long as they remain still! To get the best results from HDR photography, it's important to use the right camera settings (e.g., RAW format), take bracketed pictures at different exposures, and then edit them using image-editing software like Photoshop or Adobe Lightroom. With these tips in mind, you'll be able to create stunning images that showcase your subject in its most vibrant colors and details.
Users have searched for some commonly asked questions related to HDR photography.
Ans. HDR in photography means high dynamic range, which refers to the range of lightest tones to darkest tones captured in a photo. It's how we measure the intensity of light from highlights to shadows.
Ans. HDR photography is useful when the contrast in a scene is too much for your camera's dynamic range to handle, resulting in difficulties balancing the light in a photo. Using HDR can add greater dynamic range to photos and aims to create an image with a range of light that is similar to what the human eye sees.
Ans. Use the HDR camera setting when you struggle to balance the light in your photo, especially for landscape photography where it can display both the sunlit areas and the shadowed areas. However, do not use HDR for capturing motion, like in sports photography.
Ans. HDR technology enhances the color and exposure of an image, providing a high-quality and visually appealing viewing experience. In contrast, SDR displays a simplified and more natural view that may appear dull in comparison.
Ans. Three popular HDR formats are HDR10, HDR10+, and Dolby Vision, each with its own way of displaying HDR content and unique set of pros and cons. While there are other types of HDR formats available, these three are commonly used.
