How does ps turn daytime photos into dark sky?

1. First find a daytime material, remove the sky, dig out other areas and name them as bright layers, and then copy a layer and name it as dark layers.

2. Then create a new layer under the bright layer and fill it with a black-blue gradient to create a night effect.

3. Select a dark layer, select Layer-New Adjustment Layer-Color Scale, set the output to 45, 0.45 and 255, and right-click to set the adjustment layer as a clipping mask.

4. Select Layer-New Adjustment Layer-Hue/Saturation, reduce the saturation to -85, and right-click to set it as clipping mask.

5. Then select the bright layer, select Layer-New Adjustment Layer-Color Scale, set the output position to 0,2.05, 145, right click to set the clipping mask, and highlight the image.

6. Return to the dark layer, add a mask to the layer, select the window with the selection tool, and then erase it with a black brush. Then adjust the opacity of the brush to modify the layer. Considering that the moonlight shines from the left, erase part of the scene. Choose different transparency to decorate castles and grasslands with soft corners for many times, and achieve ideal results.
