Realsky HDRI BlueClear 1548 Description: This 32-bit HDRI map enables highly detailed real-world lighting to be used for illuminating your 3D scenes, a technique also known as "Image-Based Lighting". The map offers noise-free ultra-high detail (15k) and very high dynamic range in 32-bit per channel .exr format. The map itself and the supplied 15k jpeg image provide enough resolution for use as a backplate, even for cinema-quality scenes. Taken from real sky photography (not digitally rendered), using auto bracketing and stitched from RAW files for optimal 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: 21.18 EVs (Highest dynamic contrast on the market) Sun Altitude: 11 degrees Shooting Time: 15.48 Shot at 41st parallel in October, resulting in an 11-degree sun angle. You can calculate the correct time of day for your project using this angle and your latitude-longitude coordinates. 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, you can scale down the EXR map with Photoshop and use a lower-res version.
