Early Magnolia 2020

In this post, the photos were taken by a homemade lens Godo Lens, except no.4.
Those photos were taken by Tamron SP 90mm Macro on Nikon Z7.

I featured this flower twice (?) before using another fuzzy lenses. But, it seems the people takes the flower branch home there is no branch left on the lower part of the tree, and made me very difficult to take picture. (So, I needed to resort with something special measure. ๐Ÿ˜€ )

Walk with Godo lens

Among my homemade lens, being as if it was almost ordinary lens, Godo lens is the most remarkable lens. There was no eccentric feature like 1/2, 1/4 lens kind but two ordinary unknown origins lens put together. (yet, one of them came from my friend Gordon = hence Godo lens ) And the lens happened to produce quite normal image (if not a lots of halation) together with quite nice softness. On top of that, thanks to a Chinese helicoid ring, good convenience of close up use.

I went back to the so-called Perpetual Cherry Tree and found that the area was in a construction site. (Tree was still there and seems flowering though)

I’m not sure whether they are bamboo or reed ?
I like a natural looks quality of this macro. (Too sharp image of most of macro makes the flower looks like an animal body parts) – – – Unless the one was a forensic scientist, we may not like to see too sharp detailed flower parts.

For the cost almost nothing homemade lens, I would say, this is the good lens.

Simple Arithmetic (2)

Was that the nature of Chinese electronics, I’m not sure, the LED ring light on a Z-light arm stop to work less than a month = switching control unit has brake down. Still, connecting the USB power direct, LED light itself can be light on. —– Then wait a moment. LED power is 5V, the Ring light was said to be 8W = its mean this lighting unit was designed somewhat for less than 2A (8W / 5V = 1.6A) (and anyway, the USB adaptor was 2A Max).

Connecting USB 5V direct to the LED light can be used though, it will be an over current to both LED and USB adaptor = soon they will be burnt out. To save the broken LED ring light, it is necessary to take a measure to limit the current = need to connect a resistor. To limit the current to 2A with 5V, we need a 2.5 Ohm resistor.

So, I connected 2.2 Ohm resistor (this type of resistor is getting harder to find though) (Why the wire of resistor was not cut short was, it get hot = need to disperce the heat) ( Note, for a sake of clarity, the photo was taken before applying insulation tape. )

With some improvisation, the LED light was rescued (though, without the brightness adjustment) —– I noticed that now, we can get the same LED light on Z-light arm for as cheap as ยฃ14 ! —– some of them may not break down. —– or am I expecting too much for ยฃ14 ? ๐Ÿ˜€

Is this ZEN or nuts. (2)

I’ve put this picture before though, this IS too iconic and deserve to have its own post.

Young man who reached to his adulthood this year showing off who he is on the local ceremony event where he may see his old mates of junior school etc.

You may think, that was his display of his EGO, but you were wrong. Think, if he got ordinary mind of ordinary citizen, or common EGO such as the collective unconscious, do you think can he do the public display like that ?

Too often, this was the case that the other people misunderstood the Japanese mentality. = It was not a matter of EGO but, he was just playing the role without his own SELF. And he might have taken the role without having any order or others suggestion. = it might come like a revelation = Oh’ I got it, I’ll do.

So, a Chameleon pearched on his head. = pretty impressive !

Thousands of the people took the role to volunteer the rescue work after the disaster in such a way. —– In the same way, often the people take their work / job to became a man of “research” or a man of “the convenient store” what so ever. And that was the reason why others hear the story of “How the researcher dedicated his life to discover or develop the scientific something.”

And here again, it was not a kind of the intended dedication. But, he just took the role, since there was nothing else in sight = so, he was just doing the subject on front of him. This mental process was in fact the mechanism of the ZEN of which the key word was No-SELF. Since No-SELF = there couldn’t be any intension. = Just do it !

The matter of whether this person doing IS ZEN or not, rely on if he can be selfless when he deals with other than his Chameleon.

Simple Arithmetic

In the previous post, I mentioned the strength of the image and the size of the lens. When the inside-lens was 6mm and the outside was 14mm, of course the image made by the outside-lens would overwhelm the image of the inside-lens. The image made by the inside-lens will almost disappear like a halo caused by the dust.

.

We can calculate the area size of the lens = 3.14 x R x R – – – but we can see just the relative size as 6×6 against 14×14. In the 14×14=196, 6×6 was the inside-lens – – – 196 – 36 = 160 – – – 160 is obviously too much – – – it got to be about 72 (36+36) and the root of 72 = about 8.5mm – – – it’s mean, if the outside-lens was 8.5mm, the area of its ring shaped lens was the same to 6×6 inside-lens —– The image strength should be the same ! (The Bokeh image made by the inside-lens should be as strong as to the outside-lens’s sharper image.)

While restricting the 14mm to 8.5mm size, effect of the outside-lens was reduced = the inside-lens bokeh became more prominent.
This was not just fuzzy lens but rather sharp (kind of) lens and Bokeh lens conbined = therefore it has certain sharp (?) details.

How awkward = like a useless game of Sisyphus. – – – In fact, that was what all about the game I’ve been plying here = making the lenses.

.

And that was what Lord Buddha told to his disciple, for sweeping the garden to Shuri Pantak, knocking the door to Kisa Gotami. – – – – – Why not to me make the lenses. – – – Why not ?

I like the tone (color shift) of this picture. The watercolor paint which the brush was not well washed = its color has been fused or casted. ๐Ÿ˜€

.

Those images were made on the Nikon Z7 – – – I think, the softness was just right. (Soft mean, the neibouring pxel’s data were spilled out and infused each other hence the edge of the small details disappeared and the color mixed – – – how wide this infusion occur is the depth of the softness. Or the spread of the light. = Bokeh ! )

When the subject was good, any camera can make nice picture. ๐Ÿ˜€

.

Pla (B) Lens

Pla Lens (A) was somewhat a kind of flop in my try. —– Then, Zen wouldn’t give up. ๐Ÿ˜€ Why not to try with a different lens. Anyway, the luck is in a chance encounter (with a suitable character lens)

A lens I found was a single meniscus glass lens which can make the image like this photo —– of course, this lens could be mounted in the centre of much lager lens though, such large lens tend to have rather longer focal length etc etc. So, I decided to make a hole in the centre of this lens and put other one-time use camera lens in that hole. It took only 5 min’ when I made a hole in that plastic magnifier lens, but this time I had to drill a hole into a hard glass lens. If I push too hard, the glass will chip or worse clack altogether. = slow slowly work took half day.

The one-time use camera lens was pretty small. (I used only front lens ) Which makes the image like this. ( = unlike you expected, the centre lens produce the bokeh, and peripheral lens would creates detailed image. )

So, the concentric double lens was mounted on the camera = AND suprisingly, the image came out was rather normal. = the image was just fuzzy mediocre lens kind. (The size of centre lens was 6mm, Outer lens was 14mm which has 4.4 times larger area = in exposure level, the effect of 6mm lens was too small = negligible) (Yet still, the fuzziness wasn’t too bad even though it was far less than what I expected)

I need to get better subject —– image was somewhat similar to the Godo lens.

The fuzzy lens suite for the flower photo. Nobody complain. ๐Ÿ˜€

.

Pla Lens

Sorry to be too casual — Pla was a shorten of Plastic magnifier. I don’t remember how and when I got it. As I was looking for a lens which is large enough to accommodate a lens of one-time use camera kind, I just found it on a corner of my desk.

Pla on NZ7

Yet another fuzzy photo was a result of the newly created homemade lens, out of plastic magnifier and a one-time use camera. —– I have tested 1/2 lens, 1/4 lens kind though, they were the lens combined the out side of each other. = So, how about to try “Concentric two lenses” !

Godo on NZ7

(Incidentally, this photo was taken by a bit more ordinary (?) lens = Godo Lens.) —– You might say, when one lens can produce the image like this, why do we need yet another lens ?

The situation was more complicated = TO accommodate the other lens in concentric mean, I need to put another lens in the centre of a lens = It’s need to curve a hole in the centre. —– So, I improvised some tools to make a mini bench drill.

I just carried out the work = 10mm hole was drilled on the centre of Pla lens and a one-time use camera lens was inserted into the hole. Then the lens all together was mounted to the camera. It was mounted to the depth where one-time lens can make the focus = but too short to the Pla lens = hence, the resulting image was like the photo right.

(Ring shaped Bokeh was made by the Pla lens’s so-called “Ring Bokeh” caused by too out of focus lens. — it’s mean, even the “Bokeh lens” has to have about near focal length = out of focus may makes nice bokeh, but “too” out of focus may be too bad. ๐Ÿ˜€ )

So, this image was the worst among my homemade lenses ! ๐Ÿ˜€

A night sky —– anyway, we may not need much of details.

So, how about this ?

M m m m. —– It may need some improvement (I need to find the lens which can make softer Bokeh ! ) still, I like their paintary effects.

I can’t resist loving the image like this.

Is this ZEN or nuts ?

You may not guess what I’m going to talk. And don’t know what this is.

It was my life’s residure and its accumulation. The Lidl’s plastic tray of the Chicken.

I stopped to eat Beef 1987 when the BSE was reported. (It happen to be the same year, I also stopped any sexual contact when the first news of new diseases = later named to be AIDS was reported.) —– So, since then I only eat Chicken or fish, on top of veggie and fruits. Therefore, with my regular shopping of Chicken (about 1kg par week), those plastic trays are keep coming. —– as a kind of tempolary container, those trays are always conveniently in use still, much more trays are piling up. (If I were a good business person, I might have made a rule to limit the number of the trays in stock.)

If it was 10 or 20, nobody would bother. But when it accumulated to the hundreds, people may started to wonder — “Is it ZEN ?” — or nuts.

Number of ZEN stories are the story of the endless concentration and the result of the tenacious pursuit. = as a matter of fact, the practise in the Buddhism is nothing but the endless repetition of the same action. —– whether the matter or its purpose was the end result or in the process, its practise changes the person. So, its hard to tell, whether the continuous action was a part of ZEN practise or the problem of one’s own mental.

Then, if it was the case, how they related to the Buddhist mind of Detachment, No-clinging or live on the Impermanence kind. = you may feel the contradiction between here. —– Why you feel contradiction IS because your understanding of Detachment / Mushin = Mind of No-mind was wrong. This was the most common misunderstanding in the Buddhism. = Detachment / Mushin IS NOT an idea or thinking BUT they are the condition of the mind = like the mind was in an up-beat or sud state kind. I’m not thinking “Not to buy Beef” but I don’t see the beef there. (Not to buy Beef was not an ISM or thinking BUT it was the situation of “No beef was there”. ) So, no-one see the beef, because the one who see the beef / SELF is NOT there.

Because of, the people try to UNDERSTAND the Buddhist’s mind or try to think “That way” they can NOT get it. Buddhist’s mind IS NOT attained by intention. It has to BE in the state. When you are in, you can not aware that you are in.

So, the tray of Chicken keep accumulates —– without my conscious. I’m living without me aware that I’m living. I do, I eat , I speak what is natural to me. So, I don’t import anything foreign to my life. This IS what we call Buddhism. IF you THINK and TRY to practise Buddhism, it is NOT BUDDHISM. BUDDHISM has to reach without intention. While living as a Buddhist but forgot that you are a Buddhist, you are a Buddhist. In that state, even the SELF = you are, not existing.

I found a photo looks too iconic of the Japanese mentality ! This is what we meant “Go for all hog” —– this mentarity was behind the recovery from the earthquake disaster etc.

The young people attending the local ceremony to count that they reached to the adulthood on this year.

Godo Lens

The reason, why the sky was dull = not because the Godo lens but the sky was dull.

My friend / Cinematographer Gordon was clearing up his etc — and gave those junk to me. I don’t know how the man neither geek or otaku, managed to disassemble those, even without having tools — I didn’t ask.

What so ever the history or origin, the lens is a lens = only a matter for me IS whether it is “Usable”. —– Another day, a man offered me a very expensive industrial projection lens = more than 20cm diameter and 5kg heavy solid glass. I can guess, when it was made and sold, it must have 10 thousands pound price though —– ? what can I do with this ? —– once before, the line or graphics of the big industrial design was transeferred onto the iron material by optical projection, but now the digital technology and the laser took the work role. So, some of those old staffs may not stand even for a door stopper now.

If it was a converging lens, placing the lens on front of the camera (I mean, SLR body without a lens) and see the image. === in most of the case, the lens would show the good image only in the centre = in certain taste, the fuzzy surroundings may give a soft good atmosphere though may not necessary always.

Then give more test while stuck the lens on front of the focusing helicoid etc and try combine with other lens and so on etc for all sorts = and hundred of test click.

Since I got number of fuzzy lenses already, this time I picked one lens which has rather even image field (photo above) but as the angle of view was rather narrow, I added a diversing lens to widen its image field. ( You might be amazed to see, that the lens game can be played in such a casual manner — Yes, the game was not reserved only for Newton or Gauss kind of people)

Resulting lens was somewhat like this. = a bit strange lens. Never has any defined focus, nowhere is sharp nor anywhere is very blur.

So, makes your day always somewhat dull. ๐Ÿ˜€

This softness is more like a stocking over the lens. = the image looks like a reduced resolution image / Toy CCTV, otherwise the picture looks normal picture.

When the light doesn’t go where supporsed be, we call it aberration. But, in this case, not enough number of the light reaching and occupied each point, as a resolution. If this was the case, where the missing light has gone ? Is this an insoluble paradox isn’t it ? ? ? ๐Ÿ˜€

Strange Fragmented London

Those photos were taken in the same time of other “Fragmented Lens Photos” though, something wrong with Colour balance setting. —– Still, I like them.

Is it possible to take photo without an intention of taking photos ?
