In this framework, I consider about the low key express way and how to keep the image in gray andwhite. My idea is to go to Wharf in the morning for shooting (Sketch Plan 1). The reason is that there is enough sunshine in the morning and the color of the sea and sky is very close. I directly shoot the photos I want. However, it was a rainy day when I went to take photos, so I couldn’t take the expected photos. So I changed the plan (sketch plan 2) immediately after visiting the pier. I found a row of white buildings to make sure the photo was in Gray & White. And I chose this image because someone happened to walk in the middle of my shot, making the composition of this photo more interesting.
