The photographer is trying to tell their audience that animals can not speak or express what they are going through. People should help them when they see they are being miss treated or abused. Animals will live this type of life style until someone helps them.
What do you think happened right before this picture was taken?
I believe the dog was beaten and neglected. The dog looks helpless in the road and looks lonely. The photographer was trying to better explain his stance on animal abuse by showing a real life example.
The dog in the street is the focal point. The photographer draws your attention to it first so you will see what it is like for an animal to be mistreated.
How does cropping this picture change the advertisement?
After cropping out the words the photographers message has an opposite affect on the audience. The dog looks like he is sitting ready to play. By having the captions the photographer can really show what the dog has been through and how the dog feels.
How do the colors chosen in this photo affect the message?
The black, white and gray colors add a negative affect in this advertisement. The photographer is showing how sad and depressing it is for an animal to be abused by using these colors.
The ethical appeal in this photo is the report animal abuse to the police phrase at the bottom of the picture. Reporting animal abuse would be the right thing to do. The photographer feels this will make people want to help save animals.
