I can see the changing of color in these pictures. The color starts to spread from the central part or the focused object of the picture to other parts of the picture that are in black&white. The topic of these photographs are mainly focused on nature and relationship between people and nature.
Colors spread from the central part to the side of the picture. The bright colors and the black&white color form a very obvious contrast that caught the viewer’s attention vey well. The way you made the central part of the picture in color and other parts in black&white also allows the viewers to follow the path of where the bright colors go when they look at these picture. It helped to create a focus. The details of the natural objects such as the patterns on the leaves and flowers in these pictures also helped to create a main focus.
I think the artist is trying to express the beauty of nature and the relationship between people and nature. In the picture of a hand hold an apple. For example, the details and the color of the flower are the focus point and the rest of the picture are in black&white, so this shows the artist wants the viewers to focus on the beauty of the flower. On the other hand, in the picture of a girl touching the leaves, the color of that picture starts spreading from the girl, which I think the artist was trying to convey the message of the girl brings the color to the things around her and made the world colorful.
The idea of having some color parts and some black&white parts in the picture is really interesting, it made the pictures looks stunning. The details of the natural objects in the pictures are very nice. Also, I think the message behind these pictures are well conveyed too. The contrast of the bright colors and black&white color in these picture is clear, but maybe the transition from color to black&white can be smoother, and the picture might looks better.
