Realsky HDRI Sunset 1640 Description: This 32-bit 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 ultra-high detail (15k) and a very high dynamic range in 32-bit per channel EXR format, free from noise. The map itself and the supplied 15k JPEG image have enough resolution to serve as a backplate for cinema-quality projects. Taken directly from real sky images, not digitally rendered, using auto-bracketing and stitched from RAW files for optimal quality. Included formats in the zip file: * 15k (15000×7500 pix) 32-bit EXR file * 15k (15000×7500 pix) 8-bit tonemapped JPEG file Measured Dynamic Range: 21.28 EVs (Highest dynamic contrast in the market) Sun Altitude: 4.5 degrees Shooting Time: 16.40 On the 41st parallel, shooting in October at 16.40 gives a 4.5-degree sun angle. You can calculate the correct time of day for your project using this angle and your latitude-longitude. For example, the Vray Sun or Mental Ray Sun tool has an algorithm for calculation. If you experience memory issues and don't need super-high resolution renders, you can scale down the EXR map with Photoshop and use a lower-resolution version. I used a 2k version when rendering sample renders of this file. This map is also available in Realsky HDRI Six Pack 1.
