Take Instagram filters to the next level with Maxstagram

But :-) while your headline is justifiably front-page HN worthy, these are not "instagram filters to the next level". Take a look at all the instagram clones, and their filters. The filters suck. They are usually not very nice, and make most photos look worse.
Now of course the people who dislike Instagram will disagree with me, but as a photographer myself, I can see that most of Instagram's filters are lovingly made, and they do something that most people can't match - and it's not for lack of trying to copy them!
In other words, you can't take a bunch of random transformations and hope to get anything remotely like the Instagram filters. These things take a great effort to make.
Again, no criticism intended of your work - more of your headline....
cheers!
edit: I see that this is already a webapp, but the additional functionality I described would still be cool.
So why is this a HN? ;/
