Re: preferred sequence of parameters

My understanding is that in general for non-vector formats it should 
follow the input and for vector formats it should precede the input 
(for example when converting a cmyk pdf to rgb image).

However, better results are generally achieved by using profiles, 
depending upon your actual goal.
