Re: which lens has the most 3D POP?


The blur may enhance the effect, but it is NOT the cause of it. Too much blur can help render that fake cutout look when the transition rate becomes too fast and our eye/brain detects this. Too slow a transition rate and we see it as flat / 2D.

Getting the right rate of transition associated with the right portion of the image is part of the key to creating the effect. Too many times, that DOF separation / blur can be evident between the subject and the BG ... yet the subject in and of itself still looks cutout/flat/2D. Thrice had a very nice image way back when that illustrated the criticality of focal point placement\'s impact on creating the effect.

As noted elsewhere, the 3D effect can be achieved without any blur in the BG (Makten and the 35/2 comes to mind).

BG blur and DOF separation are NOT the same as 3D-ishness (although they can often be associated with it as an enhancement to the effect in many images).

Different lens designs have different rates of transition. Within a given lens, knowing where those transition rates begin to change is key to understanding how to render a subject with the most 3D-ishness that lens has to offer.

It kind of reminds me of the need to understand what range a Beauty Dish functions best. The only real difference is with a BD, it is light going out, with a lens, it is light coming in. The output of light from a BD is not evenly spread and as evidenced by those donuts of light you can get from them and the falloff characteristics / variance between a BD and a softbox.

With lens design (which Zeiss frequently does) that uses un-evenly spread (non-linear) transition rates, the 3D effect is easier to achieve than with glass that has very even (linear) transition rates (i.e. Oly, Leica). Kinda like trying to surf on 0-2 foot swells vs. 5, 10 or 20 foot swells ... how much \'wave action\' is present impacts how \"WOW\" the ride is when you catch it right.

Every mfr has some glass that is +/- capable of creating the effect, but it is a function of lens design (transitions), focal point, subject distance, more than aperture to create a skinny DOF / bokeh / blur. In fact, too small of an aperture is often times counterproductive to the effect as it renders those transitions to occur within the sujbect rather than near the edge of the subject (while DOF still encompasses the subject). In the case of the C/Y 35-70/3.4, most people suggest that 5.6-8.0 is the aperture range that renders the effect best, not wide open (as the \'blur theory\' might otherwise suggest).

Study the MTF\'s of those lenses (various mfrs) that notably yield the effect and you\'ll start to notice a trend in design as compared with those that render more even imagery. It isn\'t brand specific ... although brands typically carry consistent design philosophies into the majority of lenses they produce.

On a related note, different thread ... the measured sharpness resolution of glass that has non-linear transition rates can be a bit misleading compared with glass that has more linear transition rates.

Getting the right rate of transition associated with the right portion of the image is part of the key to creating the effect. Too many times, that DOF separation / blur can be evident beetween the subject and the BG ... yet the subject in and of itself still looks cutout/flat/2D. Thrice had a very nice image way back when that illustrated the criticality of focal point placement\'s impact on creating the effect.

As noted elsewhere, the 3D effect can be achieved without any blur in the BG (Makten and the 35/2 comes to mind).

BG blur and DOF separation are NOT the same as 3D-ishness (although they can often be associated with it as an enhancement to the effect in many images).

Different lens designs have different rates of transition. Within a given lens, knowing where those transition rates begin to change is key to understanding how to render a subject with the most 3D-ishness that lens has to offer.

It kind of reminds me of the need to undertsand what range a Beauty Dish functions best. The only real difference is with a BD, it is light going out, with a lens, it is light coming in. The output of light from a BD is not evenly spread and as evidenced by those donuts of light you can get from them. With lens design (which Zeiss frequently does) that does not offer evenly spread (linear) transition rates, the 3D effect is easier to achieve than with glass that has very even transition rates (i.e. Oly, Leica).

Every mfr has some glass that is +/- capable of creating the effect, but it is a function of lens design (transitions), focal point, subject distance, more than aperture to create a skinny DOF / bokeh / blur. In fact, too small of an aperture is opten times counterproductive to the effect as it renders those transitions to occur within the sujbect rather than near the edge of the subject.

Study the MTF\'s of those lenses (various mfrs) that notably yield the effect and you\'ll start to notice a trend in design as compared with those that render more even imagery. It isn\'t brand specific ... although brands typically carry consistent design philosophies into their majority of the lenses.

On a related note, different thread ... the measured sharpness resolution of glass that has non-linear transition rates can be a bit misleading compared with glass that has more linear transition rates.

Re: which lens has the most 3D POP?


The blur may enhance the effect, but it is NOT the cause of it. Too much blur renders that fake cutout look as the transition rate becomes too fast and our eye/brain detects this. Too slow a transition rate and we see it as flat / 2D.
