[BioC] Question on displaying color photo as Greyscale in EBImage

[Evan Misshula]

Hi,
If I change the colormode to greyscale in an Image does it behave the same way as the chanel function (uniformly adding the RGB with equal weights).  Or does it do something more sophisticated with gamma corrections or weights based on the image format?  I could not find it in the reference manual.

Thank you,
