Magnolia by Normal lens

N50-1.2

Again, they are the same Magnolia flower but taken by the ordinary lens = Nikkor 50mm F1.2 (set at F1.2)

N50-1.2

With wide open iris = F1.2, DOF was very shallow and out of focus bokeh was such big.

N50-1.2
N50-1.2 no ext ring

And, this was really the ordinally (without an extension ring) shot. ๐Ÿ˜€

Z85-1.4

Then, those following photos were taken by the Zeiss Planer 85mm F1.4 (at 1.4 setting and with extension ring)

Z85-1.4
Z85-1.4
Z85-1.4
Z85-1.4

Zeiss 85mm has a bit smaller F-aperture but longer focul length = so that having a more or less the same DOF —– still show a bit more solid image.

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˜€ )

Those following five pictures were taken by the other homemade lens “Pla-B” Lens” —– though, with the bad weather I trid three times to get a kind of results. 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.

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˜€

Kaki aka Persimmon fruits

There must be hundred of festive cooking and the food still, a fruits associated with Japanese New Year for me is the Kaki = known to the west as Persimmon. Tree itself is quite commom in Japan therefore to the kids grown up with the experience of picking the Kaki fruits from the tree was rather common, much more than a case of fig or peach.

Something unique to the Kaki is, there is a fun or game factor in the Kaki eating game to the kids. The fruits of some tree is very bitter and if it was too early, the fruits was also very bitter. = needs to know exactry which one is good on that moment. In the same time, there is the certain technique or tradition to make very bitter Kaki sweet. Such as to store the fruits in the certain period while putting a bit of sake to its bottom, was an exciting practise to the kids = kids always breach the line and test whether Kaki was sweet already. —– Peel the skin of kaki and let them dry under the winter sun is the other very common practise. (Kaki become a very sweet Hoshi-gaki)

So, in the New years time, eating the well ripen sweet Kaki is a journey to my kids day.

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 ?

.

Fragmented lens for London snap (A)

Somewhat the same landscape by the “Fragmented Lens” on Nikon Z7.

It is something puzzling me ? ? ? —– Advanced image processer in the latest camera straggling with unusual images and make the image even more unnatural.

.

Hi-ISO noise

Fragmented lens on Nikon Z7 / ISO 25600 / ND filter = in order to make the exposure time even longer, a dark ND filter was used as well.

Till now, I thought that the noise caused by Hi-ISO setting was just a nuisance, or necessary evil though, I became aware, in certain case, it could be an useful tool.

(ISO represent the degree of amplification of the signal —– any electronic signal would produce the noise when it was intensively amplified = whether it was audio signal, or light signal from the image sensor, when they were amplified, the residual charge in the circuit line etc etc were also amplified hence those noise was superimposed onto the main signal. — you may say why the digital signal has noise = the output signal of image sensor IS analog, until they were AD converted. = Here, in the AD converter, the depth of 12 or 14 bit etc decide the quality of the image. = one bit more mean twice as much process will be needed for each pixel of the image sensor ! = You see how enormous the task is = That’s why almost all digital camera is Japanese (inside of Leica is Panasonic) and almost all image sensor is Sony —– Who else would bother to take such awkward task in the world. ๐Ÿ˜€ )

Fragmented lens / ISO 25600 / ND filter
Fragmented lens / ISO 25600 / ND filter
Fragmented lens / ISO 25600 / ND filter
Fragmented lens / ISO 25600 / ND filter
W 1/2-B lens / ISO 25600 / ND filter
For a comparison, this photo was taken under the same condition but with the Sony A7R / Fragmented lens / ISO 25600 / ND filter (noise level seemed to be a bit less than the Nikon Z7 —– was that what the advantage to be an electronic company over a lens company ? )

Even among the oil paint, many different styles = so, in the soft paintery effect photography, there could be a grainy style —– looks not too bad.
