Realsky HDRI Sunset 1808 Description: This 32bit HDRI map makes it possible to use highly detailed real-world lighting to illuminate your 3D scenes. This technique is also known as "Image-Based Lighting". The map offers noise-free, ultra-high detail (15k) and very high dynamic range in 32bit per channel .exr format. The map itself and the supplied 15k jpeg image provide enough resolution for a backplate that can even be used for cinema-quality work. Taken from real sky, not digitally rendered, using auto bracketing and stitched from RAW files for the best quality. Included formats in zip file: 15k (15000×7500 pix) 32 bit EXR file 15k (15000×7500 pix) 8 bit tonemapped JPEG file Measured Dynamic Range: 18.04 EVs (Highest dynamic contrast in the market) Sun Altitude: 3 degrees Shooting Time: 18.08 On the 41st parallel, shooting in October at 18.08 gives a sun angle of 3 degrees. You can calculate the correct time of day for your project using this angle and your latitude-longitude. For example, Vray Sun or Mental Ray Sun tool has that algorithm for calculation. If you experience memory issues and don't need super high resolution renders, then you can scale down the exr map with Photoshop and use a lower res version. I used a 2k version when rendering sample renders of this file. This map is also available in Realsky HDRI Six Pack 1
