This shot was composed of 90 HDR shots (each HDR shot merged from 3 with 1 stop bracketing). Final resolution of about 30,500x8930px. Base color management - Lightroom, increasing color variations - 3D Lut Creator Pro, cross-balance, cross-processing and detail extraction - Color Efex Pro, final adjustments - PS.
Second image is a square crop from panorama, third one - 100% crop.
Criticism is welcome.
