freemind, there are so many in each of these fields, that you might want to pick your favorites and do a website search with Google, Yahoo, Search.com, Lycos, or one of the others. Some possibilities include:
Animals:
Veterinarians, zookeepers, petshop clerk, dogwalker, kennel worker, trainer for service dogs for the disabled.
Photographer:
For magazines, newspapers, family portraits, stills during movie production, advertising agencies, weddings and special events. Or an instructor.
Travelling:
If you mean the travel industry, that includes airlines, cruise ships, railroads, bus lines, rental cars, hotels/motels, bed and breakfast inns, museums, stadiums, convention and visitors bureaus, welcome centers, and much more.
Weather:
Meteorologists for National Weather Service bureaus, airport flight service centers, television stations, cable networks, storm centers.
I hope this helps. Maybe you can ask a teacher in a local school which offers classes in these fields.
