Thanks a lot for all your replies, I've just read the article and it's very interesting.
Now I had lots of information to decide my way on colour. My first step will be to shoot on 8x10 colour and I'll try to developed it, I have a CPE2, so in this case I'm able to try this process, after I'll try to make some prints, before using the filter that I have, if I should decide to dedicate a bit more time on colour to prepare a colour portfolio, I'm quite sure that I'll buy a little enlarger for colour.. I also quite lucky before it's easily to find in Europe this kind of materials(film,paper, chemical). Now I have lots of Black and White prints to do, so I'll pass a bit of time reading all the information that I'm finding on Apug, when I'll have more time I shoot in colour....
