With Photoshop,
• First duplicated background layer after opening file
• Background layer: adjusted exposure of entire image for right exposed buildings and pond (disregard the sky)
• Layer 1: adjusted exposure of entire image for a right exposed sky (disregard the rest of the picture) and set blending mode to normal with 44% opacity
• Flatten image and applied some minor adjustments as final touch
Hope you'll like it,
