This is a 360 HDR sky, created to make your renderings look 100% photoreal. Unlike some of the HDRs offered on the market, this is a TRUE HDR, not a FAKE one - just try, compare, and you' ll see the difference! The resolution is 8000x4000px, an LDR Tiff is also included. This HDR was taken on April 11th, at 1:50PM (13:50), in Warsaw, Poland - if you need to position the sun precisely.
Please check often for new HDRs available, the number of natural lighting conditions is unlimited, yet usually only a few are perfect for a given rendering!
