orthochromatic film is not sensitive to red light and would not be affected. very early films were orthochromatic, but it wasn't used for standard photography or film-making after good-quality panchromatic films became widely available. up until recently, ortho was used to make plates via photographic process for industrial printing (like a newspaper), and is frequently called "graphic arts film". anyone using it for photos now would likely be doing so for an artistic effect, as the red-insensitive film does not properly render the full spectrum of greys in accurate relation to the actual color.
