Ilford Ortho Plus – 5×4 Sheet Film

Ilford Ortho Plus – 5×4 Sheet Film (25)

Ilford Ortho Plus 5×4 is a medium speed, ISO 80 specialist technical black and white sheet film, renowned for its unique orthochromatic sensitivity—meaning it is not sensitive to certain wavelengths of red light. This characteristic unlocks creative possibilities, such as rendering reds (like red flowers or lipstick) as deep blacks or dark greys in the final negative and print.

Because it is insensitive to the red safe light used in darkrooms, Ilford Ortho Plus does not require complete darkness for handling, making it easier to work with compared to regular black and white films. It is ideal for studio photography, copy work, medical imaging, and forensic applications.
