Earlier quoted context omitted.
that is a problem for instagram - it isn't defensible atm. I imagine the Android team will look at it and think 'really, so people want to do that - ok, lets add filters in the next release' and done.
I know, I wouldn't use instagram or these filters anyways, but people seem to like this hipster stuff. Bigger problem for them is, they have to think what to offer their users before these vintage-effect photos stop being trendy.
Now, on the other hand, take some serious optics and truths same and unless you explicitly start blowing things out on the photo you've got something weird and artificial looking.
