    Don't confuse ortho with litho. Ortho means orthochromatic. Ortho films
    are not sensitive to red light and can be handled under the proper
    safelight. Litho means lithographic. Lithographic films are designed to
    be very high contrast, giving blacks and whites and no grays. Films can
    be both ortho and litho, either or neither. Most black and white camera
    films, like TMax or Tri-X are neither ortho or litho. Ilford Ortho Plus
    is ortho but not litho. Kodak Kodalith Ortho is both ortho and litho.
    If you want a normal contrast film that you can handle in the darkroom,
    use Ilford Ortho Plus.
