Instamatic Macro

Instamatic Macro(1)-DSC06872

Well, as I suggested in the previous post that  25 mm lens of 110 Instamatic camera is suited for macro use = So, I made a lens.

Instamatic Macro(2)-006

No doubt, this must be the most funny looking lens among my homemade lenses, since the material I used was a water bottle for bicycle.  (No problem, it only costed me £1)   The lens was fixed on the cap in the reversed direction, and with its about 17 cm extension, its makes about x6 magnification of the image.

Instamatic Macro(3)-000

Photo left was  a dead mosquito I found in the kitchen.    I’m not happy with its bit blurry image (available light with 1/3 sec exposure —– at moment I’m not using my Sony with flash light = no synchro-socket, nor adapter) —– anyhow, I need to go out to see something small insects or a kind.  (Photography is a kind of life live on the leg. = You can’t do it while sitting.)   😀



Instamatic Camera (and its 25mm lens)

I found a dear old 110 type Kodak Instamatic Camera (together with their 126 type brother as well) in a junk-box of a camera shop.  This camera shoot 12×18 mm size image with its 25 mm lens. = So, it is possible to put this lens onto Sony A7 camera and see small round image though, if it was a case, have a test on the original camera with a film would be more worthwhile. 

But what I was thinking was, try to expand the image by adding a diverging lens on front (make it to a retrofocus type lens).

But, while disassembling this camera, I was amazed how the designer made this camera complicated.  (Due to the camera has to do so many tasks = wind the film, charge the shutter, rotate the Flash-cube, change the shutter speed for bright or cloudy day, together with shutter click then return the mechanism to the first state) —– Once disassembled, never able to put it back again !   (In comparison to today’s “One time use camera” which is doing about the same with much simpler mechanism,  they looks almost like a hell.)

With an added diverging lens, its became about 32 mm lens though, the image circle didn’t come wide enough to cover the full frame.  (I need to find even stronger diverging lens.)  (Lens quality was just usable with such modification.) 


PS : As I said above, I further tested that 25 mm lens with much stronger diverging lens (which has been used for other “Fancy lens” before) = With stronger diverging power, the lens could have much longer back-focus = hence larger image circle which can cover the full frame.  The image quality of the center was usable though the corner became very bad. —– Then I gave a thought, —– for a technical challenge, I found a sort of the answer though, ? ? ?   DO I need to use this lens ?   = On the end it became rather big = While having Very tiny omnifocus “Fun camera lens” etc, why do I need to use such lens ?  —– The reason why I started to use Sony A7 was, that I can go for shooting with my camera and 3~4 lenses all in my pocket ! =  May be this Kodak 25 mm lens suite only for macro use !

So, I tested this Kodak 25 mm lens as a macro lens, while mounting it on the reverse direction —– with 18 cm extension  = The results wasn’t too bad.  😀

(Photo left was a close-up shot (about  x7) of a Butterfly Wing.  Photo right were the screen of the tablet.)

—– Not so much dramatic outcome though, it was still a fun for one afternoon.  😀


Dorkbot gathering #87

Dork-Feb-15-1-276-001 Dorkbot is one of the most peculiar social group.

 As its motto says, it is the gathering of the

 people doing strange things with Electricity.

 Other than some Core-members taking care of

organizing the meeting, there is no membership kind, but just a mailing list. = If you

are interested in, just visit their site and join them (free).


After a bit of lapse, their gathering got back to the monthly base,

and this one was for the February.


The first speaker was James Auger and he talked about Robot things and

“Somewhat a kind of kinetic Sculptures” = kinetic mean, having some mechanism

with certain electronic controls. = hence, doing strange things with electronics.  😀

And, he is teaching it to the grown-up students and going to be a Phd !

James Auger is a designer, researcher and lecturer whose work examines the social, cultural and

human impact of technology and the products that exist as a result of its development and application.

His PhD topic is Why Robot? Speculative design, the domestication of technology and the considered

future. James is also a partner in the Speculative Design practice Auger-Loizeau, whose projects have

been published and exhibited internationally, including MoMA, New York; 21_21, Tokyo;

The Science Museum, London and the Ars Electronica festival, Linz, and

are part of the permanent collection at MoMA.


The second speaker was Tim Hunkin.  Since he has been running Fun Arcade,

with “Strange Game (?) Machine” he was THE genuine Dorkbot tribe.

Tim Hunkin is an English engineer, cartoonist, writer, and artist. He created the

Channel Four TV series and Science Museum gallery The Secret Life of Machines, which

explained the workings and history of various household devices.  He has just launched

a “new London arcade of home-made coin operated machines built by enthusiasts”:

The third speaker was Restart Project.

The Restart Project is a London-based social enterprise that encourages and empowers people

to use their electronics longer, by sharing repair and maintenance skills. Through community

and workplace events we create engaging opportunities to extend the lifespan of electronics

and electrical equipment.

And the last presenter was Pollie Barden.

Pollie is an artist, activist and game designer who has designed games from the mobile platform

to the urban landscape. Firefly is a tagging game that explores temporal memory, and exploits

the balance of collaboration and competition. The action takes place at night. Your first strategic

move is the clothing you wear. Players, wearing Flashing LED badges will compete to see who can

steal the most badges from other players. However, the prize you seek may be your downfall!


I’ve been with this Dorkbot London for about 10 years, so, I’ve been watching

the popularity side of the technology. = understanding and approach of the

people toward the electronic technology.  — Years ago, the presentation of the

gathering were the handmade strange machines and its electronics.  We could

operate the machine and see its function and the way how it was made. — though,

now we got used to fire virtual weapon by pressing a button and see the enemy

smashed over a screen. (I’m guessing = I never played Game)   The operation,

movements etc etc getting more and more realistic and the resolution of the screen

is ever getting finer.  —– but how many of us does know such as a color in the screen

was generated, let alone to simulate it by the LEDs and its control of brightness. —–

I’m not happy with this trend = “Virtualization of the Life, thanks to the Technology”

—– May be I have to write about it in the other post.

—– incidentally, my pieces such as Wire Dragon, the Archer = Cupidon were

first time presented at Dorkbot many years ago.


PS: The Red cast on some photos were caused by the low battery in the camera.

And a moale on the Pollie’s pullover was because of its pattern.

—– strange things would often happen in the Dorkbot.


Odd News

Posted in Art, Buddha Figure, Buddhism, Selflessness, Who is Yoshizen, Zen by yoshizen on July 25, 2009

Strangely you may think though, I have appeared in the BBC News Site,

but not as Yoshizen, but aka /  Yoshi Imamura, demonstrating

” Psycho-kinetic Motor “ and in the video clip ” Pendulum Clock “

made out of computer HDD, and above all, the figure of the

” Buddha-2009 ” also appeared ( with the rotating light as his heart ).

http:// news.bbc.co.uk/1/hi/technology/8125259.stm

(or Click top right column / ASSOCIATE / BBC News)


I’m going to put the Buddha-2009’s full picture in this blog

in near future, though just give you a brief explanation how and why

the Buddha was depicted in this manner.

——- More than 20 years ago, I saw an image of a stone carving of

Buddha in his asceticism practice, almost skeleton like figure from

Gandhara, and I was deeply struck by it.

So that when I decided to create Buddha’s stature 7 years ago, I designed

to make him like a skeleton of which the head is a clear glass sphere

as the Buddhism stands on the selflessness.

The heart shows perpetually changing pattern of light, since

nothing stays permanent. —– etc (all the Buddhism teachings

are symbolised and depicted in here)

——-This is a sample of the Zen Buddhism in action, not in talking.

And my way to the Nirvana.
