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. The "Local Contrast - strength" parameter was decreased so the image still looks very natural.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. Increased not to brighten the shadows too much, "highlights" was increased as well in order to make the clouds more dramatic. The tone mapping settings were slightly changed in respect to the "Dramatic-bright" preset. Note that there is much more detail in clouds. On the right side there is a RAW photo after treatment withĮasyHDR. The photo on the left is a JPEG as it is produced by the camera. When the camera writes JPEG it compresses the recorded 12-bit (or better) data to fit it into 8-bit per channel format.īy doing this quantization losses occur and also typically some dynamic range is lost, because of the compression curve However image in RAW format is betterįor further processing as it contains more detail. Scene regardless in what format it stores the image data - in JPEG or in RAW. Digital camera records the same dynamic range of the This example shows the advantages of using easyHDR on a single RAW photo. Using HDR software to develop a single RAW photo. That allowed to better tune the settings, depending on the different characteristics of those two areas. The sky was processed with slightly different tone mapping settings than the rest of the photograph by using layers. Also the lens distortion has been automatically corrected with easyHDR in order to straighthen the field of view. The moving water was a major problem, but was easily overcome with automatic ghost removal. The vignetting effect was also very helpful to achieve that. That allowed to boost the local contrasts and make the image look dramatic. The noise level has therefore been greatly lowered - especially in the sky and in the shadows. However, the HDR processing with easyHDR, of 5 differently exposed photos, allowed to improve the quality, by merging together the best exposed areas. This scene does not characterize with very high dynamic range (apart from the lights, which actually take just a fraction of the image). Notre-Dame de Paris - HDR picture merged from 5 bracketed shots spanning from -1.3 to +1.3 EV.
