Thank you very much everyone, all comments are much appreciated
Re: saturation, I am very happy with the way this file prints, which is what I post-process for; in my workflow, once I am happy with a print, I just save for web the file and I am done - I am aware that this sometime may results in a bit of extra saturation on screen, but I don't really mind it - post-processing for the screen adds too many variables in the mix anyway, IMHO, to make it worth it to dedicate much time to it: on the other side of the line you get calibrated screens, not calibrated ones, color-aware browsers and not aware ones, saturation / luminosity / colours are all different, etc., you have to save images in RGB versus the larger colour spaces you can take advantage of when printing, etc. The print is what counts for me
