Fluidity and Warmth

Goes without saying but thanks for saying it. :) So it turns out the different groups need each other. No sense arguing. The engineer will never be as concerned with the result as the method. The artist is the inverse.
And were it not for the artists we may have never had the idea of
producing a machine that could make pictures.

We wouldn't have had pictures as a starting point.

Well that would be similar to aphorism "Philosophy is what philosophers do"... ;-)

I'm rather fond of the musings of John Barrow in his book "Theories of Everything" in which he talks about the immature state of human thought which leaves us still short of the necessary technical tools to do a proper job on the scientific examination of interrelated complex systems but rather good at studying reductionist systems.

Psychology (it seems to me) suffers from this problem...

"Science"? That would be the little brother of "Nature" wouldn't it?

;-)
Actually several branches of science deal with intangibles.

My field, psychology, struggles to define and measure intangibles
constantly. As does economics, sociology, ....
I'm not sure any of these three count as science in the strictest
sense. They may one day, when we have developed better tools for
dealing with holistic systems but at the moment science does better
with reductionist stuff...
Well, science is a very difficult thing to define. One of my
favorite definitions is that "Science is what scientists do."

That said, the journal "Science" (know it?) didn't have any problem
letting me publish there.

No problem with this in principle. In the case of the SD9, my problem is I just can't see anything different about the pictures once you print them out and compare them to images from convention DSLRs.

As far as I can see the SD9 pulls of a neat trick of producing the quality of the 6MP brigade from half the pixels. This is a sparkling achievement but the additional claim that there is something beyond this is what puzzles me.

Now if someone could produce evidence that convincingly demonstrates the existence of some unique qualities in the SD9 images I'd be happy to hold my hands up and share in the wonder...
OK D, let's start this from a slightly different perspective.

I've got a background in music. My 'ear' might be better than the
average Joe.

Let's take a really accomplished violinist and put him/her behind a
screen with a Stradivarius and another really, really good violin.
Have them play the same selection over and over randomly changing
instruments.

You might not be able to tell the difference. I might not be able
to tell the difference. A top rate violinist might pick the Strad
every single time.

Can some people sort photos based on 'fluidity' or on 'warmth'?
Maybe.

If they can does it mean that it exists? Quite possibly.
Something is different in the photos that allows them to make the
discrimination.

A scientist or engineer might wish to pursue the basis for that
discrimination in order to know how to build that feature into
other cameras.

A photographer might not give a damn about how the camera does it.
Just whether or not it will.

Good note DM... well represented on what you are seeking and where you are coming from. The more I can see of another's perspective the better I can understand so I thank you for that.

My ex girlfriend had some difficulty in seeing colour and it was only after I had asked her to help pick the beige color for my 2 story foyer that I realized how different she saw things.. I now have a nice light canary yellow foyer that was supposed to be beige! Sigh.

I think the biggest intangible here is the differences between people's eyes and how each person processes the informatoin. I was waiting on the D100 but after seeing many of the images it simply did not grab my eyes. I saw very coolpix like photographs.. detailed, well focused, etc etc but just had a coolpix appeareance of rmost part. yet MANY people do not see the images this way. Same 1's and 0's, same picture and yet some go " wow now THAT is an incredible picture". In general I find the D60 pictures to be the most pleasing overall to my eyes but also realize the workflow to get there isn't always simple. While I love photography and don't mind post processing I simply do not always have time to post process every picture. Photography is a hobby not a life. The Fuji S2 may ofr me then be the best overall compromise in cameras at this point in time due to it's decent in camera jpgs thoough it's images don't have the warm feel I get from the D60 post processed images. By warm I mean a sense of depth, very flowing form color to color and almost lifelike versus a picture.

When I bought my coolpix 950 and Canon Pro70, one thing that stood out quickly in the Pro70 shots was the sense of depth in the pictures. I could shoot a picture of a line of trees and in the Pro70 shot could easily see the distance between the trees and even the branches. Not a depth of field isue. In the CP950 shots the trees were often flattened and the tree branches were very mixed together and difficult to tell the distance between them. SO I sold the CP950 even though I liked the body better. But my eyes just perceived the picures differently and I am not convinced you can always answer the WHY part with science, least not in terms we currently can use.

And I had to laugh.. trust me no L Ron Hubbard here and no talking chickens in the zoo! And I don't see anything mystical in the SD9 but so see at times images that just seem to have more color depth than some of the other DSLR's and at same time seemingly that require LESS post processing to get there. I think that is the benefit thus far. If the auto settings work wel to generate decent jpgs then it MAY save time getting to a decent picture for those of us with time concerns. For me though it is still a works in progress and I doubt I would buy the SD9 until it has undergone some maturation and would prefer to see a gen 2 foveon chip in a different body but will save that dicussion for later!

So just like your previous hi fi buff aspects ( I love hi fi but mostly is a past thing as well.. think as we age our hearing tells us we can't hear what we once could lol ), it may all come down to your eyes are seeing and interpreting differently than mine. If so that is where the fluidness and warmth lie.. in the manner in which each person sees! I simply cannot give you a measurable quality to determine these parameters but would if I could! :) John

This post suggests to me that you are unfamiliar with experimental psychology.

If you were you would know that a lot of the knowledge of vision (color vision, depth perception, etc.) that we use in photography comes from the field of psychology.

Psychology as a scientific endeavor suffers from two things in particular. First is that some of the things studied are difficult to measure. Second is that some of the practitioners of the 'art' refuse to believe the data when it runs counter to their techniques.

In the mid 1800s Weber and Fechner developed the basics of 'just noticeable differences' - the minimum amount that a physical stimulus must be increased before a person can detect a change.

This is the basis of signal detection theory.

Without signal detection theory we would have no digital cameras.

(BTW, I prefer the definition of philosophy as the love of knowledge....)

Indeed. One of the early classes this engineer took in grad school was a human vision class from the Psychology department (and an automata class from the Philosophy department; only because Patrick "Mr. Axiomatic Set Theory" Suppes taught in that department).

Don't forget that Newton also became the czar of the Royal Mint and he was no Alan Greenspan :-).

But to make a work that is timeless, that is so magnificent to defy
criticism, that in its simplicity contains beauty, that contains
something outside of the cold, sterile "camera obscura" (Dark Box),
that transcends the material and moves into the realm of the
ethereal... Do you see it very often? Do most of the photos you
look at kind of cause a sort of emotional reaction but not really
enough to move you? The way standing in front of the Pieta or the
Sistine Chapel or the Guernica would move you?...

Joy,

Good post Michael. I've been an exhibiting fine artist for more than 30 years. My most formative years were the mid 60's where POP Art reigned supreme. Warholl, Jasper Johns, Robert Raushenberg, Tim Wessleman, Robert Motherwell....you get the idea. I trained as an art student during a time when anything was considered fair game as Art, any style or approach was not only appreciated but encouraged. I still feel that way. The age old question, "What is Art?" really has no meaning for me. Everything, every process, every media can be used to create an image we think of as art. Its too bad your parents droped off the conceptual boat somewhat before the fabulous 60's. If they had stayed plugged in they would appreciate that a camera is no different than a paint brush, chissel or welding tourch as a valid tool for making art. I would disagree with your assumption that all camera's do is capture a moment automatically, that anyone pointing a camera in the same general direction could achieve the same photograph. They wouldn't. As someone said above, look at Ansel Adams. You really think that if you or I were to go to Yosemite today armed with our film or digital cams that we could take an image anywhere near his? Not likely. A photograph is first conceived in the mind. All a camera allows is image capture. The real creativity happens afterwards in the darkroom, digital or chemical, and only there is the image finished inn a way the photographer saw it in his mind. Camera's record but they don't create. People with cameras create great photographs.

As for the terms "fluidity and warmth" well they are no more
meaningful than "shimmering treble" or "fast bass" or any of the
other cross-sensory terms that are invented to try and put into
words someone's subjective experience. The trouble is the terms
don't have a direct relationship to the qualities being described
and therefore mean as many different things as there are people
using them. At least with some kinds of objective measures any two
people do have a chance of agreeing that they are talking about the
same thing!
Art should provoke and challenge, that's the whole point. Its a good thing that people have different values and sensitivities when viewing things in a gallery or museum. Whoever told you that an artwork is "great" simply because its hung on a museum wall did a real number on you. Most of the work of the 21st Century you'd see in the MET or MOMA was considered offensive and dismissed as 'bad art' by the intelligencia when first displayed.

Could you possibly post an example, or examples of 'warmth' and/or 'fluidity'?

What would be very interesting would be side by sides of with and without.

What would be even more interesting would be side by sides of with and without of the very same scene shot with two different cameras. You know, this camera shoots 'warm', this camera shoots 'cool'.

----

Or let's run a little experiment. Post a half dozen or so 'warm or fluid' images and the same number 'cool or not fluid' images in some random number (toss a coin). Put them up without title or comment.

We can run a little test, have the viewers vote 'warm/cool'

If you're interested I can tighten this up into a reasonable test.

OK, let's assume that there is a certain "je ne sais quoi" to SD-9 images. Do all of them have it or just some? Do any collections stand out as having it more than others?
and at same time seemingly that
require LESS post processing to get there.
If the auto settings work wel to generate decent
jpgs then it MAY save time getting to a decent picture
This is what I'm curious about. First, this is effectively a statement that none of the other cameras produce a "decent" in-camera JPG. (Because obviously it's less work to not have to do anything at all!)

Secondly, what is the practical difference between using the Sigma Photo in "auto" mode and a Photoshop "autolevels" action? There are 4 theoretical differences:

1. The price of Photoshop (or equivalent). This is either critical or non-consequential - you either already have/need this or you don't.

2. One additional JPG save. If this matters to you then you should not be using JPG to begin with.

3. The sigma software should have access to all 12 bits. For the "autolevels" type processing, this should not be significant. Any operation that is likely to make real use of the extra bits should not be done automatically.

4. Processing time. Which workflow is quicker? On my computer, the time for an "batch" read/autolevels/write in photoshop seems to be about the same as the reported speed of the Sigma software.

So which workflow are you comparing?

For "default" jpeg, the Sigma approach is slower.

For "automatic" jpeg, the Sigma approach may be about the same (compared to "jpg/autolevels/jpg"), or faster (compared to RAW/mfgs RAW plug in/autolevels/jpg") to about the same again (if Photoshop raw support works as in the preview.)

Customized processing will be about the same as "automatic". The Sigma software may have a shallower learning curve, but it's less capable as well. Anyway, "eyeball" time dominates this processing.

It's back to that tough issue: how do you account for the software capabilities? (E.g. Olympus Camedia has an option to remove the lens distortion based on the model/exif info. Should the this software be used when measuring the amount of pincushioning? Would the answer change if the ONLY way you get get images from an Olympus camera was to use Camedia?)

Bob, I could no more do that than fly to the moon today. The whole point of this thread was to suggest that when analyzing a camera's performance one could also consider certain personal, non-objective qualities of the camera's output. You're reading the thread's catch phrase "fluidity and warmth" too literally; and that wasn't even my choice of terminology!

This thread was a carry over from one that dead-ended at 150 posts and could not be added to. J Davis coined the "fluidity and warmth" phrase. Fluidity might equate to smoother tonal gradations that look more film like (continuous tone) than most digital. It could also refer to the fact that some like me see more detail in shadow areas thereby creating a more natural transition from highlight to shaddow, this could produce a feeling of a more fluid image. But I guess you'd have to ask J Davis for his definition.

As a fine art photographer I know what he was getting at though. I might have used different terms to suggest similar characteristics such as better dimensionality or volume, image immediacy or accessibility, better overall color, etc. You see, I just can't get away from the subjective when I discuss an image, and even if I could we probably wouldn't agree. Tell you what though, when I get my Sigma, I'll post a new thread showing a comparison as best I can.

I admit that I have used this thread to suggest that a fine art photography baromoter be added to th endless pixel debate.

How about this... When you run across a picture that illustrates to you warm/cool, fluid/not copy it into a separate folder.

When you get about five of each let me know and I'll set up a little test to see if your subjective definition agrees with others' definitions.

(At least we'd get to look at some pictures rather than words....)

Why would this matter? I don't care if anyone else agrees with my subjective considerations or not. By definition they're mine. An exercise like this might be interesting but I'm not trying to convince anyone to agree with me, I'm suggesting that there are other considerations for some that make as much sense as looking at one pixel test patterns when considering a DSLR purchase.

Because without a frame of reference either by words or examples, you might as well say "I think these images are more brillig. And look how mimsy THAT one is."

Or say only that they have a certain je ne sais quoi and leave it at that. There is nothing wrong with a purely subjective impression (although it leaves the skeptics to wonder if the difference actually exists or is sample bias.)

This realy is the most foolish tread I ever have red.

All people without having post a single photograph made by them selfs, writing about the feeling some new hardware is giving them.

This is 'relegion' this doesn't have any thing to do about looking at the merrits of a new hardware aproach.

He, he the pixels are bleeding / blooming, the noise is everywhere where you look, there is lot of CA, but well it's new technologu so we will trow in about $ 1500 / Euro 1500 and a lot of more for the not to be used with other bodies lenses.

How can I can baptised ?

who still feel the idea is great, but the level of the technolgy isn't.

I was speaking partly tongue in cheek. I have an interested layman's knowledge of cognitive psychology and I find the stuff concerning consciousness etc fascinating. My comments were partly aimed at the somewhat nuttier fringes of the psychiatry profession rather than psychology as such and were partly a comment on the extreme difficulty of designing meaningful experiments in this field. I'm always impressed with the way the best researchers come up with ingenious experiments to test and verify mental phenomena e.g. working out the delay between actions and concious recognition of the stimulus.
Well that would be similar to aphorism "Philosophy is what

Shoot film for 30 years, figure out what works for you and then make a personal comment or two on the nature of photography at DPR; you'll soon see the light!

Actually its interesting you mention baptism. Here's my final statement concerning photography on DPR, The all-techno / all the time types are really gonna like this one. You're born with an eye for photography or you're not. You'll never learn how to be a good photographer by reading books, searching the net, buying a digital camera or taking classes. These things will help you perfect a technique perhaps but unless you're born with an eye that knows how to conceive and compose a shot and when exactly to trip a shutter, you'll never understand a thread like this one.

It ain't about mysticism and it ain't about magic; but it definitely concerns more than quantifiable physics. Those that know, know. Those who are scratching their heads will never know and I can't help enlighten you evidentially. So it goes. It was worth a stab though. I've had fun, hope you all did too.
