INFRARED FILM SPECTRAL SENSITIVITY

General notes

The diagram below is for illustrative purposes only and is based solely on manufacturer's published data.

Conclusion

All four of the films illustrated here are capable of producing IR-type effects, and each one has its own strengths and weaknesses. Kodak HIE is clearly much more sensitive to the infrared end of the spectrum than any other film; however both HIE and Efke IR820 tend to produce strong IR effects at the expense of considerable grain. Rollei IR400 and Ilford SFX200 are much finer grained films, but have a less pronounced Wood effect. We recommend conducting your own tests to find out which film is best suited to your requirements.
