W 1/2 lens

Here, [W] didn’t mean 2 indivisual lens. = Both of the half cutted lens. Ideally, the soft image should have the nice halo around the sharp core image —– if there was no sharp core image, it was just an obscure bad lens image. = So, how about the one lens was divided into two and the one half makes focused image and the other was making out of focus bokeh on the same one picture ?

From a Kodak (one time use ) Fun camera, the lens panell was cutted-out.

Cut an ordinary lens to optically functioning 2 separate half was not very easy. So, I did it with disposable (one time use) camera’s lens. = Cut it into half (Photo left) and mounted the one half to normal position and the other half to out of focus position (Photo middle). —– (Then I noticed that the lens I experimented makes rather nasty ring bokeh when it was out of focus —– I needed to search more.)

Photo Left was taken by the original single lens. Photo right was done by the W lens.

This W lens is efectively a w-focus lens. I experimented many w-focus image done by double exposure, or lens shift. But here I took a drastic approach to use cutted two halves lenses. —– I think, it wasn’t too bad idea. The work I took was rather awkward though on the end it was well rewarded. ( = I think —– anyhow, I got prenty one time use camera junk to try again and again 😀 )

Stabilize the Camera — Head Pod

This is yet another trick to stabilise the camera after chest pod —– or analog aproach to stabilise the camera.

Photo left is for right eye use, Photo right is for left eye use (Pod was reversed)

If you ever try to take picture of the flower in the very close-up way, without a tripod, you may well experienced an awkward trouble to hold or suspend the camera in the exact position. Image stabiliser may stop the shake of the camera in certain extent = say 0.1 mm shake or vibration though, no mechanism would help to stop your camera drifting — say 1 or 2 mm above the flower. Worse still, if you take picture while using LCD monitor, holding the camera in the air, you can’t make your hand like a solid wood. While your hand may drifting or sway, your head may not shake like your hands = so, why not stabilise the camera with your head. As a matter of fact, when you attach a flash light on the shoe, your fore head may resting on the back of the flash light, so the camera is much more stable. —– so, why not make something to rest on your fore head to stabilise the camera. = The prototype I made (in fact more than 30 years ago) works very well (but only on horizontal way and right eye use — for left eye use, the pod has to be reversed like a photo above right). (The metal piece itself was a simple cut out from a left over of a window frame, inserted into a plastic flash adaptor)

Danjiri-matsuri – most dangerouse fest’ in Japan

It seems this fest’ in Kishiwada-city, Osaka is the most dangerous fest’ in Japan —– (after Onbashira fest’ in Suwa-city, Nagano.) (so far 38 death on the record)

Hundreds of the selected participant who might be even returned for fest’, from their work in the another city, pull the float and run to the Shinto Shrine while the float of each neighbourhood competing its speed and skillful control. (If the control wasn’t perfect, its 4 ton (4,000 Kg) float would fall or clash into the house and could make a casualty even a death.) (Each float said to be costed about 100 million yen and years to make)

(Some other Youtube viz of Kishiwada Danjiri, next to this may show the fall or the clash. ( the damaged house will be compensated by the City’s Danjiri insurance.)

Every year with the tens of the thousands of participants, 32 of those floats compating each other, it is nothing but the jaw dropping extreme culture of the Japanese.

—– You may wonder what drives those good grownups to do such crazy things. There is no obligation to the local people to participate, still no outsider was ever allowed to join for fun. It is strictly local afare. There wouldn’t be any fame beyond the own locals let alone any national competition kind = in other words, it is nothing but a gainless rusty local event. —– still, Strangely you may think, there is a hidden element of the Zen which is the backbone of the Japanese ethos here. = NO obligation to participate — yet still, the locals do aware a cause / Karma borne to be a man of Kishiwada = have to run with others, even if it could cost his limb even life itself. There is no glorious theory, story, high level thinking BUT just the humble act = run. — While the one is running, what mind in his head ? = NOTHING —– This nothingness is the ZEN. When Tsunami strike, what people think ? = NOTHING. Since there is nothing, neither grief nor panic = JUST live as normal (which was accustomed = これが平常心). What you need more to live ?

While practicing hundreds of times, all the emotion had worn-out and only the attention to the control details (or the instraction programed into the body) remains = the one became almost like an automatic running machine. = DO as much for the fest’ forget any worry or arrogance.

Despite having nothing, still run, run for better. Regardless whether it looks crazy, if it brings any gain, if it is dangerous, still just run. Why ? —– Run for better ? to achieve something ? —– In fact achieve nothing. While having no mind and achive nothing, still run for better —– Why ? —– Because that IS what the Dharma’s work was prevailing.

Owara Kaze-no-Bon / 風の盆

or, yet another Bon-Odori = annual dancing fest’ in Toyama-city, Ishikawa

Yatsuo in Toyama city situated 100 km north east of Kyoto.

Kaze no Bon is a Japanese festival held every year from September 1 to 3 in Yatsuo, Toyama, Japan. Kaze-no-Bon literally translates to “Bon Dance of the Wind.” This festival, having a history of about 300 years, is recently becoming a popular tourist attraction to the otherwise sparsely populated mountain area. Wikipedia

Unlike well known Awa-odori which originated from far remoted Tosa in Shikoku island, Toyama’s Kaze-no-Bon dance is more elegant. (Though, I myself is more familier with Samba)

O-M-G — Apple

OMG — the seeds started to germinate inside of fruit !

This photo was taken by a homemade lens called Yashica Macro. https://yoshizen.wordpress.com/2016/05/14/yashica-kyocera-macro-2/

This apple must be rather old — still, not started to rotten = must be sprayed with the strong chemical to make a long shelf-life. Still, the fruit itself has its own internal clock and timed for the moment to come-out.

Of course, the apple was not created to be eaten by a man let alone by Adam. In nature, the fruits will be fallen to the ground and the seeds germinates from its rotten but nutrition rich seeds bed. —– we are only intercepting their process and robbing their opportunity.

If you are “Pro-life” activist, you may plant this seed to a pot to grow an Apple tree —– but sorry Miss Apple, I’m not such tender person (in fact, I had too much trouble before to have too many such pots of plant) I’ll just throw you into a bin. (I’ve been killing too many lives, vegetables, fruits etc etc thrown into my cooking pan etc etc = too late to pretend to become tender hearted hypocrite.)

Our vision — Photo image

This is a part of the previous post —– as I found it got very important point in the aspect of Zen (See — feel — think — what is real — truth) not only in Photography.

Rather fragile looking Scabious —– the lens showed peculiar depth of field image, and the size of back bokeh is gorgeous.

(But have you ever seen such bokeh image in nature ? —– they exists only in the photographic image = they are not real, neither your eyes are telling the truth —– So, how can you tell that the photography IS the faithful copy of the real, without knowing your own eyes could not tell what is real.) 😀

(For example, we are not seeing square building, since we got fish-eye vision as our eyes are round ball, so that, our brain is reconstructing the image following the stereotype that the building is straight = therefore, the photo of the building has to be square ! —– So, how can you tell that the photo of the building is faithful copy of the real building, = you see what I mean.)

Fuzzy Macro for flower

They are the photos made by a homemade lens called NZ-B = It’s a very peculiar lens, = utterly fuzzy though in the certain condition, strangely it shows quite sharp image.

This one may seemed to be taken by any ordinary macro lens though, with a much of amazement, even an annoyance, it was done by the same NZ-B lens on Nikon Z7, AV mode.

In certain extent, this lens would work just like a fuzzy 40 mm F2 lens.

Still, under close look, the image has quite a detail.

Don’t aske me why I didn’t come here a week ago. —– It’s happened as it happened. (That is what the life is.)

When it was far fore-focused, the image became like this = I like this. I think, no other lens ever made the image like this bokeh. And the bokeh image like this only exists photographically = never in the real world.

Hind-focused (photo left) = lens was sunk beyond the infinity position / Focused (middle) / Fore-focused (photo right) = lens helicoid was fully extended = like for a close-up shot.

(Only one exception, the photo above left was taken by the Pentax 110 Auto 24 mm lens)

Quite exotic flower — I have no idea who she is.

Very impressive though, I never seen her anywhere else. — (Is it a kind of Thunbergia ?)

But this one is very common, yet I love this painting like image. (It seemed that the loss of tonal dynamic range was not caused by the softness of the lens but by the brightness adjustment of Picasa and a very bright color = red.)

Still, the same lens can produce prosaically clean photography-like image as well.

The photographer is believing that they are the user of “Photography” though, in reality, the provider of the Photography (= camera maker, photo journalism etc) is using photographer to keep and run the industry and the idea. So that, “Photographer” was made to believe a type of photography which was provided and such stereotypical style “IS” only the photography.

= The belief IS “Photography is to make a faithful copy of the subject” while blindly believing that his own eyes is seeing the true face of the subject. —– In reality, no such certainty ever existed.

And rather fragile looking Scabious —– the lens showed peculiar DOF and the size of back bokeh is gorgeous.

(But have you ever seen such bokeh image in nature ? —– they exists only in the photographic image = they are not real neither your eyes are telling the truth —– So, how can you tell that the photography IS the faithful copy of the real, without knowing your own eyes could not tell what is real.) 😀

(For example, we are not seeing square building, since we got fisheye vision as our eyes are round ball, so that, our brain is reconstructing the image following the stereotype that the building is straight = therefore, the picture of the building has to be square ! —– You see what I mean.)

——- ! ? ? ?

Here a kind of anemone ? —– anyway, the matter is the image. (If you can make a soft image like this using PS I would like to see it !)

I’m not familiar with this flower —– pretty impressive, and it looks even cannivorous. I wouldn’t be surprised if I see the dead bodies of insects laying inside, half digested. (Do you know what IS the truth.)

And suddenly here rather humble looking flower = the color of blue jeans, Indigo came from this plant. (or larger sister of her)

(If I could stop down, the image could have deeper depth of field though this lens has no iris = always fully open F2. But considering the condition as it was fully open F2, the quality of close focused image was amazingly high !)

Then, funny looking chap = the nuts of ceder tree, not a Pokemon still, he looks very very happy today !

The world seems to be pretty peaceful.

Retrofocus

Y-Mac + Div’lens

Behind the lots of experimental / homemade lenses, I got mountain of diverging lens which came from mountain of discarded lenses. —– Converging lens can be easily used as an image projecting lens in many occasions though, not many use of the diverging lens. I did used it to make Wide-angle Pinhole and for Two element homemade lens which was to extend the focal length of the disposable (one time use) camera lens for 35 mm SLR camera.

The diverging lens was simplly stack to the front of the Yashica macro lens (focus was made by its zooming helicoid) and the size of the image was depend on the distance between the Yashica lens and the diverging lens = if it was made adjustable it will become a zoom lens.

Scavenged homemade lens / Yashica Macro is quite good lens though, it got rather limited use only for the macro shot. — Why macro ? Because its focal length was too short to be used on the 35 mm SLR even on the mirrorless camera = When such lens was mounted on the full-size camera, it was same to the lens was focused to very close. = Close-up or Macro shot.

But the focal length of the lens can be extended by the diverging lens. = So, I tried it with a diverging lens which came from a Nikon Zoom lens = It worked well !

Somewhat similar to the situation of “Twisted lens” we are discovering the “inconvenient truth” of the optics. They may not be a residents of the holly land. (I’m talking about the optical effect — utilising its effect while making precise lens-shifting mechanism etc and make usable / reliable products is far beyond the ordinary man’s capability.)

〜〜〜で、ここまで来てハタと気がついた間抜け、[ Spiritualism ]と言うのはコメントを書いた誰かではなく実は大分前に書いた自分の古いポストからの抜粋であった。

で、そこでさらに出て来る疑問は、いったい誰がこの抜粋を作ってコメントに入れたのか???---そもそも1000以上も有るポストの中から、しかも日文の内容を理解して撰択すると言う作業を、果たしてどっかのボランティアさんがやったのか、あるいは WP かグーグルの AⅠ が全自動で処理したのか??? ーーーそのどちらであったとしても、これは驚き以外の何物でも無いし, いささか怖い話でもある。ーーーつまり処理する目的で僕のブログを読んでいる目にとってこれらはどう見えているのか。ジャンクのベス単と禅がいかなる脈絡で捕えられていいるのか??? フシギ。

Leitz 50 mm-vs-Zeiss 55 mm

Casually I called Leitz Elmarit lens I used on the Nikon Z in the previous post, a homemade though, glass itself was a serious Leitz product. Hence, having a proper optical quality as we expect. —– ? was it ? = was that quality, within a normal standard ?

—– So, I made a comparizon.

This is the test image taken by the Leitz Elmarit P 50 mm F2.8 at F2.8. With the focus peaking. (Photo right was a part enlargement of the centre = the top of the tree) —– the small twig still maintain its detail though, is this fuzziness normal ?

So, to have a close comparizon, Zeiss Sonner FE 55 mm F1.8 lens was mounted to the same Nikon Z7 body and had the test shot on the same tree, same condition. (since Zeiss / Sony lens has a funny habit = keep move the focus, so that, click the shutter when focus was peaked) In the photo right, some leaves on the tree were coloured red = may be an effect of the chromatic aberration. Was it ? Wait a moment = this is not a £1 junk projection lens but a genuine Zeiss / Sony lens costed hundreds of the pounds. (Even though it was made in Thailand)

Then, I gave yet another test = Zeiss Sonner lens was mounted on the Sony A7R body and had exposure of F1.8 and F8. (manual focus) —– F1.8 image (photo above middle) was the sharpest among all the photos in this post. (Though, strangely F8 image = photo right, was soft —– very difficult to make a precise manual focus on this A7R camera)

Since the same Zeiss lens showed no chromatic aberration on the A7R body here, there is a possibility of either (1) Sony has correction program built into their image processor to compensate lens’s own aberration. or (2) The lens’s obstruction = keep moves its focus when the lens was not mounted on the Sony body = moves only a small part of lens, only to destruct the clear image, hence making big chromatic aberration on the Nikon Z body.

Yet those photos here showed very different strory. The photos were taken same as those photos above.

= Zeiss lens on the Sony A7R body. Exposed on F1.8 and F8. —– But here, F1.8 image (photo middle) showed funny chromatic aberration (red leaves)

(This is the puzzle = how those red leaves were created ? The Sony camera and their image processor seemed to hide too many puzzles.)

—– the correction program of Sony Image Processor may be working erratic. (still, how to make only some leaves red on the Nikon Z and on the Sony A7R as well looks too strange = In fact, the culprit mast be the Lens, not the camera, though, how this Zeiss FE lens can put the red color to a selected part of the image ? === this phenomenon needs to be investigated further !

This is a problem of the “Soft controled digital imaging” = it would make a pretty picture though, it may work, may not work like a Beauty App. That why I hate those artificial images. (Still, film photography can create strange phenomena too —– but, as I didn’t have an experience to enlarge a 35 mm color photo to 1.5 m big and examin the details, may be I was not aware )

Here, they are the shot to finish-off this argument (of Red Leaves) made by Zeiss Sonner 55 mm ZE lens. = The lens was tested at F1.8 if it showes chromatic aberration of red and green fringe on the roof pattern. = The result was as you see. (When the lens was fore-focused, the image has green fringe — photo above right)

And I found a very interesting bokeh pattern on the tree behind. The question is, is this the quarity of the lens which says “Sony / Zeiss Sonner” ? ? ? ( 55 mm is not special, neither F1.8 is difficult to design)

So, how about the chromatic aberration of the Nikon 50 mm F1.2 (photo middle) and F2.8 (photo right) —– a lots of red leaves seems to be here too ! = We shouldn’t be surprised. —– Otherwise we need to pay thousands of £ for a lens which shows no aberration on fully opened iris. === Only the question IS, why we need such perfect image ? ? ? (May be the obsession.) = If you want to see the perfect image, come down to the tree and see it close)

The reason why we don’t see such Chromatic aberration everyday, —– (1) We don’t use maximum F-aperture often, except in the very dark situation. And if it was dark, we can’t see such color fringe in the dark details. (2) In those lenses (Zeiss 55 mm, Nikkor 50 mm) when we stop down two or three stops, the aberration would be disappeared = hence we don’t became aware its existence. (3) We don’t enlarge the image to such big size. = so that, in the small print, the color fringe (even if it’s there) would be buried in the details. (If you are seeing the enlarged tree top photos in this post on a PC screen, it is the equivalent of seeing a 36×24 mm size photo enlarged to the 120 cm x 80 cm (43″x32″) and giving a close look.

The aberration is an optical phenomena, when the light was not converged into the focal point and spread to the surroundings as well, make the image fuzzy. Among the cause of such problem, if it was coused by the way how the light was bend differently by its color (= wave length) it was called Chromatic Aberration. As you might remember to see the rainbow 7 colors made by a prisome, when the light go through the glass they bend according to the wave length (= color). To solve this problem, converging lens which bend the red light more to outward and the diverging lens which bend the blue light more to outward were combined together to conpensate each other to the light concentrate to the same focal point (so to make a sharp picture). —– While making the light bend inward and outward, still make them to converge to the same focal point, optical designer use the fancy technique and special glass etc etc = that’s why good lens is using 10 or more glasses inside of one lens. (= making such lens hugely expensive) —– Sigh 😀

—– Still, it is rather rare to see such prominent Chromatic Aberration like the red leaves here, —– in most of the case, the fringe color appeared only on the edge of the details and make the picture just a bit soft. (Hence the most of the people doesn’t became aware such things ever existed in his lens. )

And in this point, why the Leitz projection lens I’ve talked on the begining of this post showed such character become clear, = the projection lens showes the 35 mm slide image hugely enlarged therefore the chromatic aberration would become quite visible yet, a bit soft image wouldn’t be much of the trouble as the larger the projected image, people view it from the larger distance.

.

It seems, the battle between the camera, lens keep going on. 😀
