Realsky HDRI Blue Cloudy 1515 Description: This highly detailed 32bit HDRI map enables real-world lighting to be used for lighting your 3D scenes with exceptional accuracy. Image Based Lighting is a technique that utilizes this method. The map features ultra high detail, noise-free (15k) and extremely high dynamic range in 32bit per channel .exr format. The supplied 15k jpeg image offers enough resolution as backplate even for cinema quality. Taken from real sky 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: 22.02 EVs (Highest dynamic contrast in the market) Sun altitude: 19 degrees Shooting time: 15.15 At 41st parallel when shooting in October at 15.15 it gives a sun angle of 19 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 encounter memory issues and do not need super high resolution renders then you can scale down the exr map with Photoshop and use a lower res version. For instance, I used a 2k version when rendering sample renders of this file. This map is also available in Realsky HDRI Six Pack 1.
