Bayer Pattern for EOS Rp Sensor

I have a Canon EOS Rp and wish to know the Bayer pattern of the sensor. I think it's RGGB but wish to confirm.

Hi and welcome.

Basically, as I understand it, yes - which is pretty standard. The four elements form a square with the two greens diagonally opposite.

As the array is scanned the four are reconciled into a colour value. The scan then moves one element down or to one side, and that overlapping scan gives the next RGB value. Thus by over sampling, the processor generates the same number of colour values as photosites.

Have you checked if

exiftool -CFAPattern2

works?

The only color cameras that don't use the RGGB are the Fuji with the "random" bayer pattern and the Foveon with *no* bayer sensor, since each photosite senses all three colors.

Hi Peter, thank for your reply. I did find a copy of exiftool and tried several different TAGS. None that I tried would give me the CFA Pattern. However, it did give me the idea of pulling the raw image file into another program I use ... PixInsight. When I load the file it says the Bayer Pattern is RGGB. So it is confirmed.
