I've seen some pretty interesting pictures where the date or year has been added in this method - they appear to be eerie ghosts or UFOs and will provided some creative fun to taking the images. You have be lucky enough to have a dark clear sky, lucky enough to have the camera pointed in the right direction at the right time, and lucky enough to have a meteor streak by that is bright enough to be captured by the film you are using. If you don't know what I mean by this, the next time the newscasters are calling for a meteor storm, step outside after midnight and count how many meteors you see. Now limit your field of view by cupping your hands and only look at a small area of the sky. Chances are best that you will count far fewer in the small area than in the entire sky.
Meteors appear in the sky for only a second or two and range in brightness from very dim to extreme.
They also range in color although most will appear as a bright white flash. Easy, just point the camera in the direction you expect a meteor to appear and open the film for a long exposure. The longer you expose the film, the better your chances of catching a meteor, if you are lucky that is. But you will also get star trails and a brighter background unless you are in a very dark location. Do note that if you want an image of a meteor without any star trails, then you need to guide the camera allowing it to follow the stars in they sky.
