Only a Thermal Camera is calibrated to show accurate readings when imaging glowing hot objects, a normal consumer camera will automatically make ISO adjustments to bring the scene into a visible range. Depending on how you have the camera aimed and pointed, you can make a dull red glow appear to be orange, or a white hot glow can be adjusted to look reddish. You need to know what type of imaging device was used to get which pictures in the report.
