For example, you can leave all options in this dialog set to default, and simply click Generate HDR.ĮasyHDR then crunches some numbers, and after a short pause, shows a combined image composed of information from all three images. Even if you’re not familiar with all of the terms, EasyHDR provides enough visual feedback (and sensible default options) to let you figure things out by trial and error. After loading all three images, EasyHDR displayed a dialog entitled “HDR radiance map generation.” As you may have noticed, HDR photography is chock-full of technical jargon, even more so than regular photography. The application easily handled the CR2 RAW files out of my Canon 350D camera, requiring no conversion. Once you have your images, import them into EasyHDR. The three resulting images should be identical in composition, and different only in exposure (which affects the details visible in the scene). With AEB, you depress the shutter button just once, and the camera takes three images in rapid succession, each with its own exposure value. Ideally, you should use a tripod when taking the images, and use a camera with an auto-exposure bracketing feature. I’ve tried the application with both JPEG and RAW images, and RAW images produced significantly better output: JPEG compression produces noticeable artifacts and noise when images are overlaid on top of each other. Despite packing plenty of features, it is easier to use than Photoshop because it is purpose-built for HDR.ĮasyHDR aligns and combines multiple photos into a single HDR image, and then lets you change the color-balance curve and other parameters to get the exact look you’re after.To begin using EasyHDR Pro, you’re going to need at least three photographs of the same exact scene, taken at different exposure values. EasyHDR Pro (35 Euros, 46 USD on the date this review posted) is a stand-alone application that retails for a fraction of the price and lets you create HDR images using a number of sophisticated options. Photoshop is the usual program for turning photos into HDR images, but it’s not the only option.
High-dynamic-range imaging is a photography technique that involves taking multiple images at different levels of exposure, and then combining them into a single image containing a greater amount of detail.
