Fast lenses, depth of field, and Photoshop CS6

[Sheiky]

The Lytro camera is cool. In theory, you can control the DOF, focus plane, and the quality of the bokeh, all after the fact.

Yeah it looks pretty cool. It's still a bummer that it only takes about 1MP photos(not even enough for a wallpaper ) and is quite expensive at this time I'm not sure how fast the shutterspeed on these things is, but with an f2 aperture I guess you should be alright in quite a lot circumstances.

For instance this picture would not be possible to create with the DOF function:
I think fast lenses with good bokeh are safe for now.

To be fair, I wouldn't volunteer to try to recreate it with masks and layers either I think your conclusion is right...for now(and a few years down the lne probably).
