We have corrected it to mobile light room. I changed the sky, swimming pool water, and tile walls to a brighter and cooler color, and tried to create a summer atmosphere by adjusting the overall white balance to a warmer color! It's amazing that just one color can change the feeling of ordinary pictures. When I touched this and that on my own before, I had no idea that each color could be adjusted, which is a very useful tip. Thank you so much.
