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 November 1st, at 7:25 AM , in Warsaw, Poland - if you need to position the sun precisely. As a bonus are included eight 21MPix skies taken in the same photo session - you can use them for your renderings background.
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!
