Hole on the Tape
In the age of PS and CG, now the people doesn’t necessary believe the image
they saw in a photograph. It could be cunningly Photoshoped or Filtered.
— In deed, Photographer is an expert of manipulating the image and its context.
In fact, it is an inherent limitation of any “Expressive” business =
Speak Truth, Draw Truth, anything is not perfect, especially when people got an
illusion, that the photo is a first-hand real reflection of the situation or the thing.
The more believe the more fooled, hence better detached.
Since when I revealed the reality what “The Created Lens” looks like,
before I get a praise how pretty the resulting image was, I received the
questions asking me how I could make a hole on the sticky tape so perfect ?
Well, — to a person “It’s a Photoshop” and to the other “It was cut by the best
Henkel scissors, like a magic. Good German scissors would work by itself,
like a broom in the music ” Sorcerer’s Apprentice ” by Richard Strauss.
Have look the Top Photo here. The work of scissors was captured in action.”
You see, this is an evidence. You got to believe. It’s not Photoshop !
—– So, you got to see, — a photo with a pinch of salt.
Try to cut a small hole on a sticky tape is a futile attempt whether
it was a Henkel or not. Paper Punch could make perfect round hole,
but only 1/4″ (6.35 mm) size unless you got an industrial machine.
—– Still, we might able to simulate the work of Hole Punch. = So, I did
put a metal washer under a tape and press its edge with round object.
(in here, it was a bottom of a table knife.)
We can find a different size of washer, but if you can’t find the exact diameter,
drill a hole by yourself. (Size of drill bit may not be what you want though.)
Anyhow, in the case like this, it wouldn’t be so critical.
(If you need very precise work, ask a shop doing laser cutting. But it’s not cheap.)

Meadow Flower taken by Homemade Lens
This flower meadow was suddenly created in the past 2 weeks.
It was a green patch between the buildings of the council housing estate.
Two weeks ago, somebody made a bald patch on the grass, — then after few
rains, it became a flower meadow. = Packaged Instant Meadow !
From this meadow, my regular diet of fuzzy photo was made — but this time,
I used a Home made lens which is a Retro-focus type, 2 element lens.
Sound a bit ostentatious though, in short, as the main convex lens had a little
short focal length, I put another concave lens to extend its back-focus, hence
it became a Retro-focus type. —– (Main convex lens came from a toy and the
Front concave lens was my broken short-eye-sighted glass.)
This photo was a comparison. = taken by the same
Wide-angle Double-density Pinhole lens, I’ve been using.
Note : Regardless the distance, Pinhole never posses a core of sharp image.
And rather blueish color cast, because not much glass lens there to block
the UV. —– (It’s a Pinhole ! )
For this Double-element lens, I improvised an “inter-changeable F-aperture” to
reduce a halation by stopping down. (Sound heavy “F-aperture” though, it was
just a hole on a black tape to stick on the back of the lens. 🙂 )
——– (Photo above : The clear samples of Iris (F-aperture) Effect =
——– Left = Fully open / 10 mm. Center Photo = 6 mm. Right Photo = 3 mm.
Despite the utter humble origin, amazingly this lens has certain image quality.
And those pink flower having rain drops on it —– just able to see !
So, the image was Soft and Fuzzy, because of too much Coma- aberration
still, they are retaining certain sharp image in the center. 😀
This is a part enlargement of the photo above —– Not too bad. I like it.
(Can you see the water droplets on the petals ! )
And able to give enough fun !
I have no idea, what those flowers called.
Still, I like this glowing color ! — not the Sun, but like a kindling fire in the ash.
[]
PS : May be much of your annoyance, this is it ! = THE home made Lens.
Photo Right shows “F-aperture” ! = Hole in a Black sticky tape. 😀
= To clack a nut of creativity, it doesn’t need to be ostentatiously heavy
Lens, even though the Camera happen to be expensive.
= Typical case was, just smear the Lens with sliver to soften the image.
Heavy pretense blocks the flow of the idea. = Anything can be done.
Matter is Just Do and discover a FUN.

Tilting Macro Bellows — Field Test
Following the test like previous post of homemade bellows, I took it to the park.
Setup was either Micro Nikkor 55 mm or Tamron 90 mm Macro on the bellows
which was mounted on Canon 5D Mk-III. And the most of the shots were taken
while the lens was tilted up to 30 degree. (Nikkor 55 mm = up to 20 degree,
Tamron 90 mm = up to 30 degree —– before the corner cut-off starts.)
And as no F-aperture control, all the photos were taken with
fully open F-aperture. (And hand held.)
Photo above, Right photo, you may see something strange = why the back petal
was out of focus. —– Because the lens was tilted.
Those photos were the too conspicuous demonstration of the tilting effect. 😀
But those were a bit more subtle.
And above left photo was made with Pan-focus effect and
the right was with Shallow-focus effect.
Shallow focus with rather exaggerated out of focus Bokhe.
With the Bellows extension, the lense can give even larger close-up.
There were a lots of Bees and Bumble Bees though, they were too busy.
This small black fly seemed to taking a rest.
This Hovering Fly — right 2 photos, she was in the air hovering.
(I needed at least F5.6, not fully open 2.5)
Looks quite inconspicuous, still this photo was benefited by the tilting effect.
—– Tilting the lens works well though, to have full benefit of it need to have it
from infinity, not just on the close-up = But to do it,
I need to make yet another Tilting SLR using DSLR body. 🙂

Tilting Macro Bellows Test
These are the photos of the test shot of the Tilting Macro Bellows
which I’ve shown in this blog two posts ago.
[]
In photography, Focused Plain is parallel to the Image Plain. = It’s mean if you
want a photo of the wall painting, you have to aim a camera parallel to the wall.
(Ideally, the camera should be held at a half height of the wall and in the center,
provided the lens can cover wide enough for the whole wall.) But when you want
a photo of the carpet, you may not able to hold the camera right under the ceiling.
= Then you have to take a photo from one end of the room. As the carpet stretching
end to end, to have the whole area in focus is not easy. = You have to use small
F-aperture and very slow shutter speed.—– Otherwise, use a camera which can tilt a
lens or use a lens called Tilt-shift Lens which may carry a price of £1500 or more.
——- Photo above Left is a modified camera “Conica-Tilt 2” and here with
——- Nikon PC-Nikkor 35 mm F2.8
——- and the Right, this massive lens is Canon TS-E 24 mm F3.5
When the lens was tilted 10 degree, it can focus the object 20 degree out of parallel, in
other words, even if the camera was held parallel to the wall (90 degree to the floor),
if the lens was tilted 45 degree down, it gives a sharp focus of the floor, end to end.
( But very few lens can work while tilted 45 degree =due to limit of the image circle.)
Photo above, are the demonstration of Tilting lens effects.
Photo Left, the lens was dropped hence, Pan-focus effect was created.
But in the photo right, the same degree tilted lens was aimed to the same subject
“Upside down” (Lens was tilted upward) hence giving very shallow depth of focus.
The relation of the Subject – Lens – Camera was like this.
Left for Pan-focus and the Right for Shallow-Focus effect.
When the lens was tilted, focused plain is no longer parallel to the camera,
= like on this photo, as the lens was tilted left 20 degree, the focused plain
runs almost corner to corner. So that, this kind of technique gives more
choice of the focus control = which subject to be captured sharp.
(The photos here, Micro Nikkor 55 mm F3.5 was used on Canon 5D Mk-3
with F-aperture was set to fully open F3.5)

Tilting Macro Bellows
This is a photo of a hand made close-up accessory = Tilting Bellows, I made when
I was first year in my Uni’ and it was featured in a Japanese photo-magazine.
On that time, I didn’t have proper Macro lens — I had Nikon F Photomic,
24 mm F2.8 and 50 mm F2 that’s all. And for the special close-up photo
of the plant, I was using modified Mamiya Press (6×9 format).
I made this mini bellows for use with 50 mm f2 lens and this combination
gave 1/5 to life size close-up. —– Without doubt, this must be the most
rudimental, and cheap bellows ever designed !
(You may see the extreme minimal way of the thinking in this design !)
= Lens rear cap was mounted on a L-shaped small aluminium panel and
it was connected to a body cap with a kind of bellows made out of a plastic
sheet (it was a dark curtain). Lens panel and the camera body were both
mounted on a straight camera bracket by means of 1/4″ screws which
allow the lens to be held up to 50 mm away from the body, and the front
panel (hence the lens) could be held in angle to the body, therefore
tilting effect could be easily used as a focus control as well !
I’m certain I got the original somewhere though, to use it with Canon EOS 5D,
the height of the lens is not the same and to use it with Nikon D810 would be
too awkward ( because of their setting of Non-CPU lens. ) —> I decided to
make the same for 5D, but use with Nikon lens —– Nikon lens has manual
F-aperture ring and the flange-back is 1.5 mm longer than Canon. )
Photos above shows the making process. (I used the lens rear-cap again. )
Then, to make a bellows, this time I found a black leather in a flea-market.
—– Still, bag-bellows has to be designed and stitched in rather awkward way
though, it can be done anyway = only needs stitch, — by stitch. 😀
So, this is the finished product. (Though, I’m going to change the
body mount ring to black aluminium one.)
Still, what all those works for, was remained to be seen with the resulting photo.
This is the sample of the tilting effects. (55 mm Micro Nikkor, 20 degree tilt)
(Top photo shows Pan-focus effect. Bottom photo is its reverse effect.)
If the junk material was available, the cost to make like this would be
as little as £5 if not nil. 🙂

PS: Good additional reading = [Shallow Focus — Pan-focus]

Azalea and Rhododendron
Even among the same family of Ericaceae, Azalea and Rhododendron is
very close. Often their flowers are indistinguishable. (I don’t care. 🙂 )
A bit fragile branched tree is Azalea and having stiffer branches, thick leaves is
Rhododendron —– in general.
In fact, in the mountain, both Azalea and Rhododendron are quite common.
—– well, Azalea in the grassy meadow and Rhododendron grows much higher,
even rocky ridged area of the mountain.
Even in the wild, both of them got variety of colors though, in most of
the case, one area got the same kind and the same colored flower.
So, in Japan, we climbers are proudly boasting, has seen the special
variety of the Rhododendron in the particular mountain.
It seems, the Rhododendron has an alkaloid (poison or medicinal constituency)
which rise a blood pressure, hence some are believing it has an Aphrodisiac effect.
In the mountain Shelter, I observed a group of the people experimenting it and
showed the effects = feel hot and itchy on the skin and having a feeling that their
earlobe are swollen. (but not their part of the anatomy —– how shame) 😀 😀
So, when I read a description in the book “Third eyes” —— Tibetan family eat
honey pickled Rhododendron flowers. = I was very suspicious about the
authenticity of the book = then, later I discovered that the author was in fact
an English Milkman. Whole book was just a fiction.
So, don’t make a Rhododendron Salad.
They are pretty as they looks ! (nothing more, nothing less)
(Whole picture were taken by Canon Fish-eye Zoom 8~15 mm F4
—– it’s a pretty useful lens ! )

Pippin’s Art
As I described in the other post, South London Deptford is a peculiar town.
And an artist Steven Pippin must be the most well known (to the certain
people) peculiar resident there. On the Deptford High Street, his studio
or work-shop having a sign as an Optician. (I haven’t ask him why though,
I guess, may be because he is dealing with “Optical things” 🙂 )
So, in his “shop front” there are numerous “Kind of Camera” or “Used to be a
Camera” which are heavily modified or some might say “almost destroyed.”
Whether his art lies in the resulting images created by those cameras or the
Camera itself is the Sculpture —– or the action to make those Cameras are
the conceptual art ? —– is a question but I couldn’t find an answer yet.
Like a typical artist, he seemed to care little and just doing what he want to do.
(Right = Pippin. Center = Julian, and James —– we three were from the
Wireless Workshop in Greenwich)
Often, his creation was more of the destruction — such as to make a camera
explode or shot with a gun.
But his recent project [ Ω = 1 ] is a kind of autonomous machine to keep a
pencil standing upright. = It’s a X-Y optical feed-back system, and he want to put
this machine installed on top of the tall tower. —– (on the end, he seemed to
persuade the people of the [Sky-tree (634 m tall)] in Tokyo to install this on top.)
(I guess, this optical feed-back system would work only on the solid ground.
If the machine itself, with optical detector altogether moves (not just wobbling
pencil), its movement may go beyond the feed-back range, as the Sky-tree’s top
sways more than 5 meters, wen hit by an earthquake or strong wind ! )
—– incidentally, the link for the anti-shake structure of the Sky-tree Tower
[Shin-bashira] and [Mitsubishi Counter-weight system].
By the way, the reason why Sky-tree was 634 m tall was because it’s in Tokyo where
used to be called the county of Musashi. (to pronounce 6=Mu, 3= San, 4=Shi) 😀
Photo Left = Carl Zeiss’ folding camera “Zeiss Ikonta” was burnt to produce
the image of the “End of the Camera”. In his “Aladdin’s cave” it’s hard to
guess what there and what for or what would it become to. 🙂
He got fully equipped work shop and all those tools are pretty familiar to me.
Though, to the local folks, the world see through his window must be
the remotest world, let alone to understand the significance of the
[Half-cut Camera] !
So, whether his studio is transparent or invisible to the people or not,
a gap on the street itself shows the mysterious zone in the human mind.
