Photographer Teresa Berg replaces a Rottweiler's collar with a pink scarf. She picks a string of pearls to complement a dachshund's coat. She is taking glamour shots of shelter dogs, hoping her spiffed-up subjects will be adopted more quickly."Most photos show dogs in cages, looking dirty, and mangy," says Berg. "I consider my work like an antismoking campaign. We have to make adopting cool."
Her father wouldn't allow her a dog of her own as a kid. He did, however, show her how to use a camera. Together, they took pictures and developed them at his office.
Living in Dallas at 24, Berg found her perfect roommate on the street: a Border collie-Shetland sheepdog mix she named Gpsy. Berg always has a soft spot for the ones that don't have anyone to love.
For years, she worked as a real estate agent, but she quit in 2006 to launch a photography business. Searching the Internet for a dog to adopt as a companion for Max, her Pomeranian, she was instantly put off by the photos online:"They had dirty laundry, dirty dishes, and empty pizza boxes in the background," she says.
Berg finally found Flash, a 12-year old long-haired dachshund who was a Dallas rescue dog. She went to pick him up and ended up volunteering to take pictures of all the rescued dogs there for free. As more dogs went to the program, she took their pictures too. In the following year, after the photos went up on the website of the Dallas-Fort Worth Dachshund Rescue, the group's director noticed that adoptions had doubled compared with last year. She attributed this to the professional photos. "When dogs are adopted that quickly, it makes room for others off the streets, "Berg says.
Over the years, Berg has developed some tricks to snap flattering pictures: position dogs so that light falls on their faces, and shoot at eye level. In 2011, hoping to inspire more photographers, Berg posted video seminars on focusonrescue.com. About 75 people per month now watch her offer tips for taking quality pet photos. She's gratified to see the recent wave of well-shot dog photography on shelter websites and social-media sites.
In the past couple of years, Berg has added two dogs to the Dallas home she shares with Flash and her husband: a dachshund named Jasper and a Pomeranian named Maggie:"I want to take all the shelter dogs home; that's the hard part," Berg says."I have a particular affinity for dogs with gray muzzles."

Why did Berg, the photographer, put scarf and pearls on shelter dogs?
查看材料

A．Because she enjoyed taking fancy pictures of dogs.
B．Because she was a faithful antismoking campaigner.
C．Because she wanted to make their adoption quick and enjoyable.
D．Because she felt relieved to make them look attractive and stylish.

Love Animal Shelter

Foster Owner Program
You can help save a dog's life by becoming a foster owner until we find a loving owner to adopt your pet or until we reunite them with their original owner. We have dogs of all ages for you to care for, and many require special attention.

Although being a foster owner is one of the most rewarding experiences in the world, its emotional, physical, and financial demands should be given careful consideration. For this reason, we require all of our applicants go through an orientation program at our shelter so that they can get used to the responsibilities of caring for a dog and decide for themselves if they would like to continue doing it. We will also have one of our staff conduct a home and lifestyle evaluation to determine if each applicant's living situation is suitable for one of our dogs. Additionally, once a dog has been placed in your care, our adoption center will be on call 24 hours a day, seven days a week to help with any situations that arises.

For more information on our foster owner program, including testimonials from current and previous foster owners, visit www.loveanimalshelter.com.
What is the purpose of the advertisement?

A. To encourage people to adopt a pet

B. To encourage people to become foster owners

C. To encourage people to donate to the animal shelter

D. To encourage people to volunteer at the animal shelter

Experience the World in 3D Game

Ever wondered how your cat or dog sees the world?Now you can look through their eyes with the first 3 D game that recreates the vision of different species based on scientific evidence.

The online simulation,created by the French 3 D design company Dassault Systemes,with the guidance of veterinary ophthalmologist（眼科专家）Didier Schmidt-Morand , mimics（模仿）the vision of five animals-cats,dogs,rats,hawks and bees-as a player steers them through Place in Paris.

Due to differences in field of view,colour perception and night vision,for example,sight can be drastically different from species to species."In terms of performance,eyes are as variable as different models of cars,"says Schmidt-Morand.

The game was created by using existing virtual models of the square then applying effects based on descriptions of each animal's vision.Dassault's 3 D software allows a scene to be modified by adding blur or changing the colours,angle of vision and depth of field.

Although it was easy to recreate vision inferior to that of humans-cats and dogs,for example,have trouble distinguishing shades of red-replicating features that we are unable to see was a challenge.Hawks have more detailed vision than ours,whereas dogs are better at seeing movement and have a wider field of

view."We used virtual cameras to precisely simulate larger viewing angles but the result made people nauseous（令人作呕的）,"says Schmidt-Morand."So we tweaked（微调）the model to give a sense of the wider view without sticking to reality."

The rat's view also departs from reality:because they are near-sighted,everything more than 15 centimetres away is a blur,so they typically move close to walls to help them navigate."A rat would never throw itself into the middle of an open area,"says Schmidt-Morand.The simulation for this animal is supplemented with a map in the top right corner to help determine the rat's position:because of their limited eyesight,most landmarks are obscured.

The game is intended as an educational resource and players can discuss their experience with others through community features on the website.If there is interest from schools and zoos,the team hopes to recreate the vision of more animals.

The game developed by Dassault Systemes is the first 3D game recreating the vision of different species.
