A Lesson in X-Pro
i sometimes feel that mobile phone photographers take for granted the "retro" filters provided to them. in reality, most of the filters are not retro at all...but are traits characteristic of toy cameras. toy cameras have weird like leaks and bokeh effects...and are thought to be "old school" mainly because they use film.

Here are examples of photos put through the "X-Pro" filter in instagram:
