Which post-processing adjustments are typically possible after saving an infrared image?

• A. Changing focus and distance
• B. Changing emissivity only
• C. Changing resolution only
• D. Changing emissivity and reflected temperature

Answer: (D)

Adjustment after saving an infrared image focuses on how the temperature data is interpreted rather than how the scene was captured. Emissivity describes how efficiently a surface emits infrared energy, and changing it alters the calculated temperature since radiance-to-temperature conversions depend on this property. Reflected temperature accounts for infrared energy reflected from the surroundings that the camera detects; adjusting this helps correct the estimate of the true surface temperature when reflections are significant. These two parameters directly affect the temperature map you see in post-processing. Focus, distance, and resolution are fixed during capture and aren’t altered afterward in the same way.
