A Question for the Community - Help/Advice Wanted

How do you save your layouts - i.e. how do you get to the finished image that you upload online? Do you add any lighting effects or filters, adjustments or sharpen before saving? Do you flatten, save to web, save at 72dpi or do you do something else entirely?

I'm just starting out (less than one year scrapping) and I'm convinced I'm doing it all wrong. I feel like I'm missing something that the people-in-the-know, know (lol).

If you could give a brief outline of your own processes, that would help a lot.
