3D ? Pop ?

ok so i thought i would do a little test se see i i could get it when i want to get the effect.

ok so i tested out all the Fstops and il show you 3

first to clear things up this is shot on a nikon d7000 with a MC Pentacon auto 29mm f2.8 using an adapter with corrective glass.

so thats a crop factor of 1.5 1.5x29= 43.5 and that corective glass gives i beleve and extra 1.1 so 1.1x43.5= 47.85

so this would be equivalent to close to 48mm on ful frame.

first pic f2.8

so thats the first

second pic at f4.0

there we go
now from f4 to f5.6 there wasn't alot difference (the was a bit and i liked f4 better)
last one F8

i dont know what you guys see but to me it seems f4 pops the most
even the slight difference in DoF affects the pop effect a lot in my opinion.
and it might have something to do with the sharpness too.

sadly i dont have a wider lens except the tokina 11-16 but i think thats to wide but i could try i at 16mm[/img]

Thank you rwg!!! You are the first one to mention what I was thinking all along:
It's must appear like a "real" image to our eye.
I believe it is the right combination of subject (+ sharpness), transition zone and background, plus rendition of the background (bokeh) that gives images that appear "natural" to the eye!
To get all these things right needs not only good skill, but sometimes simply luck.

The focal lenght is not very important.
The aperture has to be chosen, so that the background is out of focus, but not too much, so this it totally dependent on focal length and distance, so use whatever Fstop is "required"! Even more important than background is the transition zone! There must be elements binding the subject and the background in this transition zone! The rendition of the zone and background are of course lens dependent, the lens is of extreme importance IMO! But don't forget; All the artistic decision considering perception must be met!

On Canon lenses:
I really enjoy my Canon lenses, but I don't think they do much 3D. (Don't confuse it with "pop", plenty of that possible with large aperture lenses.)
That's the reason I got into (old) MF lenses, there is just a something that modern lenses can't do Wink

I believe several things are needed:

1. Composition
2. High micro-contrast
3. Accurate focusing of the subject
4. An f stop which produces a sharp subject
5. Some shallowish depth of field somewhere in the image

yeah i totaly agree manualfocus-g i think we got the ingredients (or at least a bunch of them)
now we can try to achieve it when we want the effect.

ah yes centaur i think you are right about the focal length i saw some 200mm shots of birds in flight with very ugly buildings in the background but the rending of these out of focus buildings seemed natural and made the birds pop. ofc the birds were sharp enough to look real.

It is our eyes and brain that makes the impression of 3D, based on the perspective (i.e. the reduction in size of the background). If the background is so blurred it becomes indistinct, then the impression of 3D is lost.

I think the most important aspect, more than the depth of field, is the ratio of the distances from camera to subject and subject to background. The focal length has to be factored in as well.

while lens formula probably a big factor in this. it determines how micro-contrast sharpness bokeh ect. ect. is handled.

It cant be just lens formula or els we would have had an answer to the OP question already. because in that case certain formulas would always generate 3d/pop pictures. And it would be easy to point out the different lenses.

How about this for 3d?

Distagon 35 1.4 Wide open. This is not only separation of the main subject...I can feel the space between everything in this picture.

nikkor 55/2.8

you don't have to try hard with that one

impressive since there is so little contrast--- pen 42/1.2 @ f/8 +

1956 canon LTM 85/1.5

one last:

leica 50/2 M v4

when shaded subjects pop.....

the newer CV RF lenses really pop---the 50/1.1 is a real 3D machine stopped down some.

Here is my thought:

Leitz Summicron-R 2/50 wide open. Shot was captured with K10D stitched from 2 images.

3D?

Plasticity is the ability of a lens to convey the images exposed on the film the precise sense of photographed volume (a ball looks like a sphere or a circle?).

Difficult to explain in words (but only a few minutes and two lenses, one plastic and the other not-plastic, to make it clear to anyone what I'm talking about)

So plasticity is an objective parameter ... impossible to measure.

i think you mean plasticity not 3d

Great thread and some wonderful shots !

One of my first shots with my new C.Zeiss 85/1.4. Sat at a cafe waiting for a client. Shot at f2.8.

Very interesting topic!
Well, it isn't a MF lens, but i really love the 3D rendering of my Pentax 31mm Limited. The best lens I've ever used:

Closer:

Even closer:

Samyang 85mm f1.4 is very good for subject isolaction, but not so good for 3d, because of the longer focal length and the telephoto compression -I think- compared with the 31mm, but a I can get what I consider a "3d effect" image from time to time, especially with far subjects:

Awesome!
