An Analysis of why these pictures are used.
There are 3 pictures in total attached on this post. Both pictures focus symbolically on the Rubber Duck on the Victory Habour.
In Picture 1, the duck is facing a crowd of people, who are taking photos of it. The caption of the picture is interesting, too -- "Spreading Joy Around the World". It tells the duck is spreading joy around the world. The Rubber Duck is spotlighted under the darkness of the sky, suggesting it acts as a “Star” that can capture people attention. This picture, apparently, focuses on the relationship between the Rubber Duck and the crowds. The Rubber Duck is kindly cheering Hong Kongers up. As the picture is used in “Discover HK”, which is meant to be showing the bright side of our city to attract people. This picture, showing a harmonious atmosphere, would be a perfect choice.
In Picture 2, the Rubber Duck is floating on the habour with an iconic background of Hong Kong— skyscrapers and the shaver-like IFC Mall. The caption, "One Giant Bathtub", is funny, it compares the Victory Habour as the giant bathtub of the duck. The Rubber Duck is floating with some boats, constructing an image that it is assimilated into the groups of boats. And with the caption, implying Hong Kong is the home of the Rubber Duck, so it can bath here. The picture is used in CNN news to inform the readers about it’s arrival. Therefore, the photographer tried to show that the Rubber Duck is now become a part of Hong Kong these days.
Picture 3 is a combination of the previous pictures – with the crowds taking photos of the duck and the iconic background of Hong Kong. It is posted on a newspaper. The purpose of the news is also to provide information of the arrival of the Rubber Duck – as CNN news did. Besides, it also includes that the Rubber Duck beams lots of happiness in Hong Kong, so people gather together to have a look at the Rubber Duck on picture 3.
To sum up, even though the pictures have the same main character, with different angle and background, the place they are going to be posted, they will have different messages.
