    Looks like a bit of exciting technology is coming from Adobe in Photoshop.

    It looks like it could be impressive, but there's no telling how it will work in all situations. I guess we'll have to wait for May to see more.

    I thought PS/CS6 already had an unblur function (I've tried to use it but was not very successful).

    There is something, but from what I can find this is an entirely new technology.

    Focus magic

    There is lots that can be done with sufficient computing power and the trade off of dynamic range for resolution (or vice versus).

    The more one knows about the source of 'blur' the more effectively and efficiently it can be reduced. For example motion blur is different from defocus and the best tools for 'correcting' each is different.

    And can they do this in reverse so we can reduce depth of field?

    There's several programs on the market that do this such as Alien Skins Bokeh and OnONe's perfect focus.

    My impression is that these programs use masking techniques to blur selected portions of the image. I'm wondering whether a program that can identify and de-blur out of focus elements of an image could also identify the blurred portion of an image and, rather than sharpen it, blur it further in proportion to its original blur. Are you aware of any programs that work that way? Seems like this could be very valuable to smaller format photographers.

    Very impressive. This will probably make me upgrade.

    No. A slightly out of focus image is a vey different beastie than the 'focus' blur from DOF. One can use a set of images at different focus positions to extend DOF (see axial deconvolution methods).

    Theoretically if one knew the optical point spread function and the distance of each object in the field of view such a 'correction' would be possible - you can imagine such situations are exceptionally limited.
