Quantifying "pop" ... that can be a tough ^ gig.

Kinda like quantifying the "pop" of a cork from a Champagne bottle. It's likely a fair statement to suggest that different Champagne's and corks will "pop" at different rates. Nobody is sitting around with gauge to measure when one "pops" more than another (i.e. to quantify it) in terms of Nm, psi, etc. Yet, folks have a different sensory response to those that pop more abruptly than those that pop less abruptly. Compare that to cracking open a beer, or the origins of a soda pop (previously corked) vs. a screw top. The rate of release will be more / less rapid, and the abruptness is attributed to the "pop" (i.e. abrupt rate of change).

Ours is the sensory visual response to the differing rates of change ... slow vs. rapid (focus, hue, tone, saturation, aberration, etc.). When that rate of change is more rapid (cumulative attributes), folks sense it as having more "pop".

Defining "pop" ... that is something that I think is rooted in the abruptness (i.e. rapid rate of change) of attributes as it moves into / away from the plane of focus.

To date, (as mentioned elsewhere) there has been no consensus on what the term "pop" means ... I've proposed this explanation before. If someone has a better explanation of how to connotatively define it (ideally, in concert with its etymology / denotation), please do so ... but, until someone brings a better way to explain / define what the term "pop" is inferring, this is my .02 on it (consensus, tbd).

YMMV

Can we close my thread?


It is A “secret,” but not THE secret. There are a variety of techniques that are found in images that are thought to exhibit whatever “3D pop” is, and the image I commented on (including that quote) uses quite a few of them.

Two reasons, perhaps.

1. There is a fair amount of misinformation in this thread, of the sort that can mislead less-experienced photographers looking for panaceas to go down an expensive dead-end road.

2. Perhaps more to the point, after well over 2000 posts, it is clear that there is no answer to the question posed in the original post and the tread title… and no further light is going to be produced by another 2000 posts.

I’m also amazed at the inconsistency among supposed examples of “pop.” Several do seem to exhibit something that might be termed “pop,” typically attributable to identifiable characteristics of the images, often linked to particular techniques and approaches. But others posted to, I suppose, “prove” the “pop” quality of certain specific lenses are really pedestrian images that reside in point-and-shoot country.

Since I am against attacking anyone’s photographic skills in so-called technical threads (that’s often a nasty technique of distraction), i’m not going to call out any specific photographic examples…

This is one of the fundamental problems: trying to deduce the thing (lens) that best produces an outcome, the definition of which no one can agree on, is a fool’s errand.

An interesting game for someone (not me) to play would be to answer the question: “If the term “3D pop” did not exist, what equally succinct term would apply to whatever this thing is?”

- - -

In the end, imagine that you are a person who has seen photographs with this quality that you think is attractive and appealing, and that you would like to get that quality in your own photographs and better understand how it is obtained.

You would be FAR better off looking at the visual features of those photographs, understanding what visual qualities produce this effect that you like, and then setting about applying those techniques to your own photography. These include effects of lighting, color, contrasts, selective highlighting, selective focus, composition, use of perspective, posing subjects, and more.

Any decent lens will get you there.

Even if there were a universally accepted definition of 3Dness or whatever is called, unless it came with a measurable attribute(s) or characteristic(s), it would be left in the eye of the beholder.

Any decent car will get you to the grocery store ... but some folks still like to discuss engines ... particularly the ones with more rapid rate of change (i.e. acceleration).

If you don't want be part of the discussion ... then, don't (pretty simple, imo) ... moreover than an incessant need to tell others that they shouldn't be discussing the topic they have chosen to discuss, specifically about gear, specifically in a gear forum, specifically in a thread, specifically about optics, and how it pertains to human visual perception response cues.

If gearheads want to talk about bore / stroke / .030 over / magnesium alloys / etc. ... would you waltz in to the garage and incessantly tell them that any decent car will get them to the store, etc.

Sometimes folks just like exploring things more deeply than the average Joe ... but, by all means feel free to exercise your wherewith to perpetually interlope.

Just an .02 for consideration.

A poor comparison, because all of this can be measured, as can many things related to lenses, such as resolution, vignetting, etc. The farce we are dealing with here in this thread would be more comparable to the discussion about whether a certain miracle stone in the tank or on the rearview mirror promotes more relaxed driving.

You pretty much completely missed my point.

But, sure, I’ll play.

Let’s say you need to go to the grocery store. You know that some people manage to get there in five minutes, but somehow you always get off track and it takes you at least 10 minutes. You really want to get to the store faster!

Someone says, “Well a BMW is faster than that Toyota you are driving!’ Get a BMW and you’ll speed up your trip to the store!”

You get the BNW and you DO get to the store faster — on average, it now takes you 10 minutes and 9 seconds instead of 10 minutes and 10 seconds! But you do own a really fancy car! (No offense to BMW drivers. They are fine cars.)

Meanwhile, someone else says, “You know, I don’t think that the BMW is going to help much. If you got to know the streets around here a little better, and perhaps if you didn’t always drive to the store at rush hour, you could cut your drive time in half. Or if you explored the neighborhood a bit you might even consider that other store that is half as far away.”

Buying a Stradivarius won’t make you t a better violinist. Working on your technique and interpretation will. ;-)

Car gear heads (my late father-in-law was one) also love to talk about things that can't be measured, like the sound--often described as the purr--of an engine. I think aficionados of almost any endeavor have their measurable things they obsess about and their subjective things they obsess about. The 3-D pop thing being discussed in this thread certainly is one of those subjective things that some photographers obsess about. I don't find telling people not to obsess about such subjective things to be anything other than a waste of one's breath. So, I agree with RustyBug--trying to tell people not to obsess about the 3-D pop thing really isn't going to stop them from doing it. Even if I don't share the same obsession, I am happy to let those who do discuss it as they see fit. I don't think there is much point in telling them not to obsess over this issue.

I'm mostly just curious if folks see a diff, or see no diff at all. It's not intended to be an answer, but ... rather, a question.

If folks would care to respond with a very simple "Diff" or "No Diff" (their own criteria of whatever it is they are looking for / defining), it might be interesting (or not).

No explanations needed, just "Diff" or "No Diff". Discussion can be later, after we get some responses.

I prefer the 28/2 Apo-Lanthar images: more contrasty on the focal plane and with more pleasing out-of-focus rendition. I think both of these aspects might contribute to 3D pop.
The images taken with 50/2 lenses are both so flat that we can only appreciate the sharpness and excellent CA correction of the Voigtlander 50 Apo, one of the best lenses ever made.

Since we are dealing at present with a 2-D medium, any impression of depth has to be in the mind of the beholder, impossible to quantify. I know what 'does it for me' but couldn't say why.
Yesterday I was at the dentist, having a crown fitted. This had been 3d printed so no messy mould needed as in the past, a 3d scan of my mouth was done.
Set me thinking on photography, maybe we will see stereo cameras again, with output fed to 3-D printer? That would be 'interesting'
No, I haven't been on the fire-water, stone cold sober.

Yes, 50mm comparison does not show any 3d (pop-or-not) at all, so it's irrelevant to the topic of this thread.
28mm comparison does not show any differences that contribute to 3d-pop in my eyes, I also think it's APO's contrast that stands out (unless pixel-peeping for resolution or it's a CA heavy scene).

Thank you, Dan.

You have been the most amazing source of inspiration and encouragement on a subject I endeavored to study years ago and share what I've learned with our fellow members regarding Trompe' Loeill. I'll never forget all that you have done to help (de)focus the depth of this niche conversation, and the impact you've had on my (and other fellow members) joy of our beloved craft and conversation(s) with others on Fred's most wonderful site. You have spent an enormous amount of time, effort, attention and energy to leave your mark on my life in a way that I cannot begin to express with words sufficient to convey, how much you have ensured that I'll never forget that you are ...


Dan the Man.

Yeah, it looks like a dandy.


As to the 50/2 APO, here's the thread on it ... #9 of the bicycle presents nicely, too (imo).
https://www.fredmiranda.com/forum/topic/1625777/98/#lastmessage

I haven't gone through this thread on the 50/2 APO to the degree that I have for the VM 40/1.2, but that if the #9 bicycle shot is indicative of more that the 50/2 can bring to the table, we'll see (bearing in mind the comps above for diff / no diff). Might be worth a look, too. I'm consider pairing it with my VM 50/1.5 II ... different optical design approaches. Not soon, but down the road, maybe.

My take on it is that Voigtlander's approach here may be similar (will compare 28 APO / 50 APO / 40/1.2 designs) regarding transitions, but when going faster to f/1.2 for the 40 ... APO is off the table wide open ... sort of a "near-APO" maybe.

The salient point being that a faster f/1.2 aperture (i.e. more BG separation, alone) isn't fully necessary as the sole contributory to the rendering.
