From Doyle McKim, Lewis County Writers Guild.
Most of us know that a character cannot remain in viewpoint and see the glint of his own eyes, or the blush of her own cheeks. We must also remember that a character cannot remain in viewpoint if he or she assumes terms or situations outside their realm of knowledge. If you were writing a novel set during the civil war, you would hardly say that your character took cover behind a boulder the size of a Volkswagen bus.
Beware the more subtle. A girl from Chicago might find it romantic to watch a cowboy ride his golden stallion into the sunset, but how does she know a stallion from a gelding? Would she know a hillside covered with pine from one covered with fir? a rifle from a shotgun? Of course it’s more descriptive to write in detail rather than generalities, just remember your viewpoint and the knowledge, or lack of it, you want your character to show. The better we know that, the better we know the character.
