Here's another how to video from Nokia regarding the Nokia 808.
In this one, Nokia shows an awesome feature of the 808's camera, and its called "bokeh effect"
I don't know much about photography and its various techniques and honestly I never heard of the word bokeh before until I saw this video...
bokeh allows you to blur targets on the and focus on ahsts needed as seen in the video.. the result is outstanding..
This is one feature I cannot wait to try out on the 808 as soon as I get it :)
