One of the main reasons instagram is popular is that it blurs out details such as skin blemishes, giving the appearance of being more attractive.
I don't have any beef with removing skin blemishes, it's adding over the top effects that hands down ruin the photos! Heck i've even seen local newspapers use that "instagram blur". Even webpages with photoshop actions
I work in a photo department. I can't stand instagram because of the square photos. People are dumb as hell, "What do you mean my square photo gets cut off when I order a 4x6?". I spoke with a Fuji tech today, he agreed, square photos are something that should have died years ago and never been brought back. It's a non standard!
IIRC, wasn't there square film as well?
