    Default Is DOF created by photoshop same as the lens?

    I'm a beginner and i'm wondering if the DOF recreated by photoshop looks the same as the ones created by the lens. For example, can i create the same portrait on a 50mm f1.4 lens using photoshop. Thanks in advance.

    Depends on the scene and your skill. You can definitely select the background and apply blur to it. With skill, and for fairly uncomplicated backgrounds, it can look pleasant and authentic. I haven't seen convincing software bokeh though, but then I haven't really tried looking for it. But it boils down to : do you want to take photos, or do you want to spend your time editing photos?

    reduction, if you are skilled and patient enough

    probably yes, though to make sure that it looks EXACTLY like, is subjective

    increment of depth of field, forget about it.. there is only so much you can do.

    its never quite the same. The lens blur in CS2 tries to replicate the effect by having you key in values for the blade curvature, blade leaves and shape. It is better than gaussian blur but you still cant get the shaped bokehs the way a prime lens would produce.

    Read this for a better understanding.

    by the way, it is Out Of Focus blur (OOF blur) you want, not DOF, which is the depth of the area that will be in focus...
