replacing fresh tomatoes for canned

I want to make the following recipes, which calls for canned tomatoes, but I have some fresh San Marzano tomatoes that I need to use up. Can I replace the canned for fresh without changing anything else? http://www.saveur.com/article...

I think it would work fine and you wouldn't need to change anything else (although perhaps a bit more liquid if they aren't very juicy). In a fairly recent thread, @pierino said "Go by weight. A large can of tomatoes weighs 28oz. Substitute an equivalent measure of fresh tomatoes. You will want to blanch and peel them first but that's pretty simple. It's great to have delicious canned tomatoes out of season, but right now go ahead with the fresh ones." (http://www.food52.com/hotline/16392-how-to-sub-fresh-tomatoes-for-canned)
