One way to visualize your characters more clearly and be able to give more precise descriptions is to collect photos of them . . . or, rather, people who look very much like them.
If your characters are unusually good-looking Americans or Europeans, it's fairly easy to find clear photos of faces. For example, look at:
✥ catalogs for upscale stores
✥ advertisements in upscale magazines
✥ fashion magazines
✥ TV Guide
✥ People magazine
✥ Us magazine
✥ Web sites for TV shows and movies
✥ Wikipedia entries for actors and actresses such as:
—"List of American Film Actresses"
—"List of British Actors and Actresses"
✥ Web sites for modeling agencies; find lists of links here and here, or search on Google
Web sites for modeling agencies are particularly useful because you can sometimes specify details such as height or hair color and so drill down through the files to relevant photos more quickly. Be aware, though, that modeling agency sites tend to have bells and whistles that make them take forever to load and search.
If your characters are American or European and have bland, average to good looks, sources for photos include:
✥ ads and catalogs for stores such as Sears, Penneys, Kohls, and K-Mart
✥ most mail-order clothes catalogs
The most difficult characters to find portrait-style photos for are people of non-Western ancestry and people who do not meet current Western standards of attractiveness. I never found a satisfactory photo for the heroine in the first novel I wrote, who was short, plump, and dark.
I had more success with Like Mayflies in a Stream, which is set in ancient Mesopotamia. Although I never found any photo that looked like my conception of Gilgamesh, I found my heroine, Shamhat (at right), by Googling "Iraqi models" and following a link, and I found a model for Enkidu (below at left) when I saw football player Troy Aumua Polamalu on TV.
✥ Web sites for modeling agencies for other countries; find lists here and here.
✥ Wikipedia entries such as:
—Lists of Actors
—List of Samoans
—List of Native Americans
✥ Magazines for other cultures such as National Indigenous Times (a magazine for and about Australian aborigines) and Native Peoples Magazine (for and about American Indians)
✥ Query what you are looking for (for example, "Iraqi woman") on Google Images
✥ Query what you are looking for at a stock photo house (some lists of houses are here, here, and here.)
✥ Ads in city and regional magazines for professionals—lawyers, dentists, doctors, tax preparers, and so on
✥ Magazines and other publications that feature pictures of accomplished people, such as college alumni magazines, business magazines, and company annual reports
✥ Web site for Ugly Models modeling agency
Or create your own interesting-looking people by morphing photos together or transforming a photo at Web sites such as:
✥ Morph Thing
✥ Face of the Future
