General notes:

• Rollei IR400, 120 format, ISO 100.
• B+W wratten #29 filter on lens, and Kiev Orange Filter
• Metering handhled w/ Luna Pro Digital
• OK Results. A bit underexposed. #29 Red more underexposed, about one stop.
• Printable. Moderate discernible IR radiation effect.
• Toning was a mix of black or green tea.

Conclusion:

Film needs more exposure and ISO 100 was too high a setting for use with this level of filtration, although development appears to be good. Using an R72 filter and/or increasing the length of exposure would be required for stronger IR radiation effect.
