Look in tiff.h, TIFFTAG_PHOTOMETRIC indicates the type of the image.

it's possible to read only one color chanel from tiff(CMYK) let say cyan and save it as greyscale?
Yes. Anything is possible for a programmer. I don't think that any existing libtiff utility will do that though. But ImageMagick and GraphicsMagick *can* do CMYK channel separations.
