Focus Shift (A)

Focas Shift-1A-A09A8705

Focus shift is a kind of the holy grail to me in the soft image photography

together with the camera vibration.   Since the images of both techniques

were affected by the three dimension or the depth of the subject, it wouldn’t

be replicated by a digital graphical manipulation or a soft filter.

(effect of filter appears everywhere flat, same as a graphical effect —

otherwise it needs to give days of manipulation, pixel by pixel.)

So that, I’ve been working for this quite a while, hence such as the lens

 in the photo appeared here long ago. (Lens was Canon FD 50mm F1.8)

Focas Shift-2-001

A device I made was not so complicated electronic controller which takes

the signal of the shutter-open from the Flash-hot-shoe then to start the   

AF motor in the lens, hence focus-shift (from the pre-focused point.)

= in the effect, the resulting image has both focused sharp image and

 an off-focused, fuzzy halo around.   The beauty of this technique is,  

it is not rely on the lens’ aberration but the out of focus Bokeh, therefore 

it can be done with any focal length. (as long as I got such modified lens) 

(For another lens = “softness made by the vibration of the lens” = which

can be done with ANY = non modified lens, would become ideal.)

(Click and see enlarged photo — the sharp detail is still there. )

(The field report would be coming soon.)  🙂
