Just wondering,

I am new user to mac, and I have install Photoshop element 4.
But seems like, not able to locate the channel tab next to the layer tab?

What I tried to do is to use the channel mixer to convert my photo to black and white
Is it true that there is no such funtion on a element software?

I am also a new user for Photoshop, I just happen to read in the book that channel mixer is a good way to convent to black and white?

please enlighten me..thks
