Small blue/green orbs in image

Last updated: 04-01-2016


When capturing directly against light or lamps, reflections may occur as small blue/green spot/circles.


This may be caused by internal reflection between the IR cut-off filter and the image sensor. However this is exceedingly rare. The best solution is to change the angle of the image slightly to adjust the angle of incidence.



In rare cases, Phase One can provide a camera back without an IR-cut off filter to avoid reflections. In that case a IR cut off filter in front of the lens is required.
