The first answer to this question says that
when saving images in TIFF, each pixel holds three colors' data and because of that, the file is larger... and RAW only hold monochrome data in each pixel and use RGB colored filters and hence the file is smaller
I also didn't get what it's said in the latter sentence.
But, what I have learnt is, a pixel consists of three sub-pixels (as in here) (btw, dots means sub-pixels, right?) or four (as in Bayer pattern).
So the my dilemma is, doesn't a pixel hold three colors' data (in sub-pixels) whatever the format is? And did that answer say that the three or four sub-pixels hold a single color (in RAW)?
Please clear me up....
