Realsky HDRI Sunset 1650 Description: This 32-bit HDRI map allows for highly detailed, real-world lighting to be applied to your 3D scenes using the technique known as "Image-Based Lighting." This map features noise-free, ultra-high detail (15k) and extremely high dynamic range in 32-bit per channel EXR format. The map itself and the supplied 15k JPEG image offer sufficient resolution for use as a backplate even for cinematic quality. The image was captured directly from a real sky, not digitally rendered, using auto-bracketing and stitched together from RAW files to achieve optimal quality. Included formats in the zip file: * 15k (15000 x 7500 pix) 32-bit EXR file * 15k (15000 x 7500 pix) 8-bit tonemapped JPEG file Measured dynamic range: 20.26 EVs (the highest dynamic contrast available on the market) Sun altitude: 1.6 degrees Shooting time: 16:50 When shooting at the 41st parallel in October, and at 16:50, it results in a sun angle of 1.6 degrees. You can calculate the correct time of day for your project by using this angle and your latitude-longitude coordinates. For instance, the Vray Sun or Mental Ray Sun tool has an algorithm that allows for this calculation. If memory issues arise and you do not require super-high resolution renders, you can scale down the EXR map with Photoshop and use a lower-resolution version. For example, I used a 2k version when rendering sample images of this file.
