converting to cmyk - 'convert to profile' vs. 'color settings'
I am trying to understand how to convert from rgb to cmyk for printing in photoshop. I know that you can select image-->mode-->and then cmyk color. I also saw that you can select edit-->convert to profile and seemingly convert to cmyk that way as well. What does destination space mean? I also saw that you can go to edit-->color settings and also convert to cmyk through that?
Which one should be used to convert to cmyk for printing? Why would someone use 'convert to profile' over 'color settings' or vice versa?
Thanks!
