How silly !

While checking my own post (I need = notorious trouble of mis-speling), I realized “Wait a moment, why did I need to make a screen shot of Aster flower, while having such fuzzy pinhole — How silly”

Whether you believe or not, I’ve completely forgotten the existence of Double Density Pinhole.  I should insist, this was not a demented memory but the Zen No-mind.   🙂   —– Zen only deals with the things on front = if not on front, it is not exists, since the mind is not clinging the No-existent things.

Anyway, to find the “Pinhole Machine” for Sony A7  and  For Nikon (+ adapter), and had the shot of Aster with ISO 25600 setting.  (More artefact noise would appear with longer exposure = dark evening)

aster-pinhole-nik2-001

The left photo was a Double density Pinhole. — Nikon type Pinhole machine has Multiple Pinhole as well. (Photo right)

aster-pinhole-sony3-001

They are the compalison = Pinhole machine for Sony A7 —– As the pinhole is much closer to the sensor, the images are much wider and the color on the edge is sifted to magenta. (Left is DD, and the right was mono-pinhole though, not much present fuzzy effect.

Pinhole sounds simple and easy to make though, — because it IS such small, very difficult to controle = very difficult to replicate the same effect.

So, I have to be contented to have this fuzziness on Autumn Color.  🙂

Exploding Cinema or Firework

exploding_cinema_ivy-house1-001

Last night was a so called Bonfire night and may be to coincide with it, a cinema session “Exploding Cinema” was held in south London.

I popped out carring A7R camera with a homemade “Mag lens” attached on it.   But as I saw the fireworks over a park,  soon I realized that I put a wrong lens. 

Mag lens makes the largest halation among my homemade lens = bright spot like firework become just a big blob.  Still, that’s what I got then, — never mind, it won’t kill me in any way.

exploding_cinema_ivy-house2-dsc03912

Exploding Cinema has been running by the volunteers, film enthusiasts for the past 25 years.  (And I know the current figurehead, Matt for 20 odd years.  When I met him, he was a visual media technician and I was an almost a dancer in residents of the Fridge Club in Brixton.)  Exploding Cinema is showing all the films submitted without selecting, and running totally independent. (so that, the waiting list said to be more than one year to be shown there)

exploding_cinema_ivy-house2b-a09a6891

exploding_cinema_ivy-house3-3-001

So, the films shown there were from short comical Anime to professionally made quite serious one. (A film produced by Chris R’s “Drone Strike” was a heavy staff good enough for the big screen.)

exploding_cinema_ivy-house4-2-001

And MMM    🙂

When I popped out, the fireworks exploded over my head, —– I found, the lens character of big blob is quite pretty in deed.  Ha ha ha,   😀

Battery Charger

charger1-a09a6890

I’ve got numerous number of Battery Chargers and I made quite a few by myself, since I’m buying many Battery type tools etc. = its own charger comes with.  On top of it, I’m using many photo flashlight, LED ring light etc etc. so that, I’m a big user of the battery and its chargers.

But here I’ll talk only about the Chargers came from Lidl. — (As far as I know, Lidl sold 2 battery chargers (Ni-Cd, N-MH single type battery) in the past 10 years or so, and I’ve bought and used both of them. 

Lidl sells the things really cheap = it’s no doubt but the reputation is

“Half of the goods we bought, may not be used and the rest of the half would break down within 6 months”. —– Still we may not bother to claim a money back, because they are anyway so cheap and we may not bother to keep and find the receipt.

charger2-10-001

Their larger, universal type charger could show “Start fine” — but one of the charging post had stopped to function. (Photo right)

charger3-9-001

And the more compact type charger (only for AA and AAA) started to make a big noise from its cooling fan and one post stop to charge, then burning smell came out!  

(Incidentally, the photo right showed the plastic cover of the battery shrunk and exposed the metal can = because of the heat-up with a rapid charge = it could cause a short-circuit and a fire)

charger4-8-001

I check the inside circuit and found one transistor has been burnt out.  Its small SMD transistor  HJ31 was a common PNP transistor though, it’s not easy to replace it = we can not buy just one, but may be 100,  if not 1000 in one lot.  

Still, common PNP, SMD transistor could be replaced by an old common PNP transistor. (50V, 10~50Mhz type though, it was not in a critical Hi-frequency circuit but simple on-off) —– So, I replaced it with an old transistor. = It’s worked perfect.   😀



PS :   When I talked about this repair work to the computer geeks at the WW meeting, they responded with rather typical view, saying that normally the people do not think to repair the equipment using such old style transistor. — Then, I realized that this repair work was the Zen response.  With normal thinking, people wouldn’t conceive such idea to repair without having an identical component.  Yet still, completely open Zen mind could say Why not ! = Why we needed to be confined to one idea.  As there may not to be any idea to restrict us.  All those idea, restrictions are our own making in the mind. — unless we try, we never see a possibility, even if it might be only one in million.   (If you think, the Zen is to twist the leg and the enlightenment is How to giveup.   YOU were wrong.   Zen and Buddhism IS the matter, How to OPEN the eyes)

Aster — (Secondly Photo)

aster1-dsc03697

aster2-dsc03628-001

Aster (Aster amellus) must be one of the most common flower here.Its name Aster came from its star shape (why the round shaped star was sheen by such astric * shape  is the other problem ! )  😀

aster3-dsc03715

Leave such problem to a neuro scientist to argue.   I did some screen shot of its Aster’s image and created the secondly images.

In my policy, I reject the use of Photoshop or in-camera “Effects” kind, because they were the creations of somebody else. Not mine.

So, whether the artefact of “Hi-ISO noise” is a Digital process or a Character of the hardware is a point of the argument.

aster4-dsc03629-001

aster5-dsc03718

On process, the screen shot was made with ISO 25600 setting and during the exposure, the focus was shifted to give a blurring effect.

(Originals were shot by a homemade Mag Lens and the copy was made by Gaudy Lens on Sony A7R)

Coconuts

coco1-dsc03589

Everybody knows what the Coconuts are, still this Nuts (?) Fruits (?) has number of myth or misunderstanding.

Long time I was made to believe that the coco2-dsc03587name Coco was a Hawaiian word of the Monkey as a Coconut got a face like pattern, since I’ve read it long time ago.

But now I know, it was simply a Spanish or Portuguese word means head or skull.

—– Another myth was that the Coconuts spread through the sea current = ride on the wave and reach to the another island.

So that one Japanese song 椰子の実 (Yashi-no-mi) was telling such fancy story of sea voyage though, the counter-proof of such story was well documented on the history.  = When Captain Cook reached to the eastern shore of the Australia, there was even a single tree of Coco palm there to alleviates their thirst. 

Neither Columbus found any Coconut when they reached to the Caribbean Island.  = Coconut was brought by the human hand.

—– There are many Coconuts products, from Coco-drink to Coco-cream, Coco-powder = they are all from the same tree = but a difference was whether it was young or matured. 

(After a while, green Coco’s juice become whitish meat inside)  🙂

Sow Bread (Cyclamen) — (Secondly Photo)

cyclamen1_dsc3484

cyclamen2_dsc3416

(Top photo was in fact a screen shot of the second photo. — Second =

original photo was taken by a homemade Mag Lens and the

screen shot was done by even fuzzier  Gaudy Lens)   😀

Sow Bread (Cyclamen) was introduced to the Japan about 150

years ago.  Botanist then, Saburo Okubo named it as a direct

translation of the English name Saw Bread to  Buta-no-Manju !

(How beautiful ! ! !)

cyclamen3_dsc3418

Most of us think, Cyclamen as a potted flower associated with

Christmas. — As a matter of fact, they are the best-selling plant 

in the winter.   So that, to find its flowers in a shady ground of a

public park was a rather surprise to me. (I have no knowledge or 

a proper reference book to distinguish whether this one was a

wild one or just humble but a tough type for an outside garden.)

.

Biggest selling plant mean, it has a very competitive big market

= how to attract the customer, so to find a good sale’s point is a

serious business.  So that, adding a nice smell to the normally

smell-less Cyclamen having a fierce battle. —– On the end a

Japanese scientist has succeeded to develop a nice smelled

variety by manipulating / tampering its chromosome.  =

Made a cross bleed between C.persicum (2n=48) and the

C.pupurascens (2n=34) with scent, to (2n=41) then by the 

use of  Colchicine alkaloid from Saffron, made it to (2n=82). 

(And further process by exposing to Ion-beam to change its

DNA to create nice color with nice smell.)

The whole process sound very complicated and awful. 

Somebody, a kind of  “Activists” may start a fuss, still others may

say it was not actually tampered the Gene but only the change of its

container (Chromosome) which technique has been used to creates

many Seedless fruits such as  the seedless grape, water melon etc.

(When the number of chromosome set was changed to x2, x3 …

such irregularity obstructs the normal development of the seeds

= hence seedless fruits.) 

Although, the plant can produce the fruits, its plant was fertile =

even a cross-pollination couldn’t produce next generation = no

possibility of its spread of an abnormality = safe to the Nature.

—– ?  is it ?        

(As a matter of the fact, our Nature has been bombarded by the

cosmic ray, nuclear particles etc. which is causing the damage /

change of the Gene.

(Which may have contributed to the evolution of many species.)

—– Even on the worst analogy, an Atomic Bomb on Hiroshima,

must be caused millions of genetic mutations if not just burnt to

the death, didn’t create a single Super cockroach nor Giant man.

Genetic mutation might cause the abnormal development or

abnormal growth of the cell or organ (which was called Cancer)

if not die straight, but to have a chance to create any distinctive

new feature to the species is a rare rare occurrence.

To see what is natural and which is not, or how far we can go is a

very difficult question (unlike Activists are shouting) = may be

our useless ideological imagination (and a want of nice smell) is

creating more trouble.  😀

Hop

hop1_dsc3397

A  plant Hop (Humulus lupuls) is a very peculiar plant, which

belong to a small family of Cannabaceae.  From its family name,

you might have guessed, yes, Hop is a cousin of Cannabis.  But

they two looks so different — How botanist found that they

were related ? ? ?    And you might have heard that a stronger

kind of Cannabis, Skunk was created by a crossbreed with Hop. 

(Though, it was unlikely the cross-pollination, nor grafting, so 

some said even a genetic engineering — how it was done

was still in a mystery.)

But, in generall, Hop was onlyhop2_dsc3401

associated with a beer.

As a matter of fact, me to see

this plant, it was only the third 

time on my life.

First time was on a farm hedge

in the Hertford Shire.

Second time was in a fringe of

a park in the south London.

Then this time, it was a hedge of a

non assuming ordinary hose in south London. = It seems

she always appeared in the most unlikely place. (Of course,

as I didn’t go to see it “likely place” = Hop garden of Kent

or Hop yard of a west country.) — So, the question was,

how this plant or its seed came here ?      And my biggest

question IS how Hop was added to a beer in the first place.

— Has people got a habit to chew it to fleshen the mouth ? 

Then got an idea to put it into a drink ? 

Otherwise, it was the most inventive / creative idea the

mankind got.   (Though, I don’t drink beer.)   😀

(Those photos were taken by Tamron SP 90mm F2.5  on

Sony A7R)

Pen-F Zuiko 38mm F1,8 Lens on Sony A7R

pen-f-38mm1-a09a6822I don’t remember why this lens was still here.  This Olympus Lens

has been in the end of shelf many years.  It was a Olympus Pen-F’s

standard lens though, Pen-F was a half frame camera (24×16) and its

flange-back was 28.95mm, the lens couldn’t have a focus other than

a macro use, I might have had a test of close-up photo on Canon 5D.  

— The funny history of this lens was, on late 80s, one of my friend

photographer who wanted to experiment, “To get a rough-grain soft

image, using a Push development on a Cross-process” = In order to get

rough Grain, he wanted to use even smaller original = hence Half-size. 

—– So, he asked me to make an adapter to use Nikon Lens on a

Pen-F body.  =  I made it out of Nikon close-up ring and a Pen-F

mount from this 38mm lens = So that, this lens lost bottom mount.

= in normal sense, it is an utterly useless junk

—– though, while Googling the Net, I found the people using Pen-F

lens on the Full-frame Sony camera !    (Unlike the lenses for the

Cropped size senser DSLR camera, those Olympus Lenses has

been made to cover (well almost) the full-frame image circle !) 

pen-f-38mm2-001To modify this lens for a Sony E-mount camera, I found a M-39

Leica lens to E-mount adapter has the almost a right size. 

So, I screwed  M-39 ring to the back of Pen-F lens (+ some

adjustment for infinity focus) = = = Voila, Pen-F lens on A7R.

pen-f-38mm3-a09a6830The test shot on general

distance was usable but

not bliliant.

(The lens might have 

sold as a spre parts =

damaged goods)

Still, Close-up photo

was pretty good.

(Photo below, middle)

Though, there isn’t much soft texture (It may be because

the Sony A7R camera or its image process.) (Photo right)

pen-f-38mm4-001

Olympus Pen-F Lens is very small, (In comparison to such as

Nikon lens + adapter on Sony) pretty nice match to the A7R,

so that, I’m quite happy to have this  F1.8  wide-angle lens.

What ? – 3/4 second on “B” setting ?

a09a6803On the 100 years old lens,

an instruction was given,

“On a dull day, use a tripod

with the “B” setting and

give 3/4 second push.

—– What ? ? ?   In 100 years

ago, could a user of camera

give 3/4 second push to

camera’s shutter ? 

—–  Well, my guess was, that the camera user then must have

practiced a lot for the precise push of the shutter lever.  

The English tradition was, to count the second while saying

One Monkey, Two Monkey, Three Monkey ~ ~ ~ ~ !    Therefore,

only say “One Mo” would be half second and “One Monk” would

be 3/4 second !      (Really ?   You must be kidding )   😀

But I’m not sure whether a French photographer ever did

“Un Monkey, Due Monkey ~ ~ ?       equivalent Japanese practice

said to be, say “Obaaachan” (Granny) for one second and

“Obachan” (Aunty) for half second. (— Count many second by

repeating  “Obaaachan” while counting on fingers.)

— Try Count One Monkey ~ ~ ~ Ten Monkey while watching a

watch and get the rhythm.  (One day, you may need it.   😀  )

Kodak Red Bellows Lens

Kodak-op5-001

(Photo left / Kodak folding No.1A — image from CameraWiki)

Well, even if you were a keen photographer and have an interest to the old cameras, you may not know the Cameras with red bellows. — They were 100 (110) years old Kodak Pocket Folding Cameras. (I got two of them though they are in a box, bottom of the pile of 50 boxes = I’ll show you a photo one day.)

— I bought just a lens in a junk box of George’s Camerafare shop in the Portobello Market.

red-kodak-lens2-002

When the camera mean big wooden camera, Kodak started to sell “Pocketable” folding cameras for the consumers.    (Be prepared, the size of a pocket then could take even today’s laptop.   😀  )

red-kodak-lens3-001

We may guess, it was a situation like teaching the people to have a selfy and send it through Net phone.   

The Kodak preloaded the teaching App on the camera body = all the instruction were written there. =Such as : Use 1/100 for Moving Objects or Gray day, Use Tripod and with B setting for 1/2 second !  ETC. ETC.  (Shutter was triggered either by pressing a lever  or using an Air pump ! )  In fact I was rather impressed to see the quality of the manufacturing standard = after 100 years, they are still working ! )

The camera was made by Eastman Kodak Rochester USA though, the Lens was made by Bausch & Romb Optical Co. Rochester, USA (once before, Sunglass, Ray-Ban was a part of this company) of which they call, Rapid Rectilinear lens. ( though, it only meant, no distortion)

red-kodak-lens4-001

The second photo above center shows the lenses = front and rear element seems to be identical (both showed the same focusing length = symmetrical design)     And each lens seems to be a single lens.  

Mounting the lens on a bellows to have a test shot = the image seems not bad ! 

red-kodak-lens5-001

Thanks to the bellows extension — have look a close-up.

red-kodak-lens6-001

Then to see the So-called Softness on the same test bench.   It seems this lens showed no Zeiss kind of softness.  (The photo left was taken by Sony A7R —– to be fair, I did the same shot on the Canon 5D Mk3 as before (right) —– in comparison, Sony showed much higher crispness and Canon seems softer) —– Still, this matter needs more critical test to find the reason.

Much more serious question over this old Lens IS, = No focal length was found still, the extension of the bellows showed it is 175mm.   Even though the front plate was saying F4, the diameter of the lens IS 24mm = F-aperture should be F7.3 but from a measuring of the exposure indicates that this lens got a brightness of only F10. —– It is quite puzzling.

= To see the old lens is fun in deed, still it is not necessary a gold mine to find any nostalgic image !  (Unless, use a homemade emulsion on a glass plate together)  😀

Such as a photo of dried Rose by A7R above — this sharpness might be created by the digital process in the camera, not an original optical image.)
