Impressionists Flower Photo — like oil paintings/DD Pinhole Images

These are the Photos of  [Wide-angle Double-density Pinhole]  😀

Just a pretty pretty sweet pictures.  Nothing else. (Don’t ask too much.)

Now a day, sharp pan-focused images are everywhere,  especially “Phone-Camera”

become even more popular. (The smaller the camera, image become more

Pan-Focused)  —– Though, our eyes are not Pan-Focus = Brain only sees where and

what the person wants to see and feel irritated to see Pan-Focus image —-> Thence,

Google issued a program for Android called [Google Camera (Google Play)] which

makes an image “Selectively Focused”.

I can make a photo, well Pan-Focused if I need but other than that I’m not much

fond of sharp image = rather like an ambiguous image, double image etc.  🙂

So, I’ve spent many years to seek and try all sorts of “Soft Focus” techniques. = This

Double-Density Pinhole with additional Concave Lens, which made it Wide-angle,

is the best so far.  Not all-rounder yet it produces pretty jokey image.  I like it.   😀

 I don’t think even a Botanist wants to see the details of common garden flower.  

What we need is just a coloful flowery air !

It seems what I need to add here is, a distant back ground

and the blue sky over it and the Victorian Ladies with umbrella !

Carnival in Greenwich (3) — Impressionists Pinhole Photo

I expected that the bold color and the shape of Masquerade and the Carnival costume

would suite for the Pinhole photo though, in real life, it was not as colorful or bold.

This photo is a reference, how it looks like through normal lens !

Double density Pinhole creates big hallo around brighter subject,  

though, this softness seems to be a bit too much to be the Impressionist’s.  😀

(In this post, the results of  two days shot = wet cloudy and fine / bright day

were mixed, hence, it might give confusing looks.)

Wide-angle Double-density Pinhole was mounted on Canon 5D Mk-III.

Leiz 35mm Lens — filter size

A camera shop who noticed me got

a soft spot in the particular number,

sold me a lens, Leiz Elmarit-R 35mm

F2.8 which has been converted to

the Nikon mount.    By doing so, the

lens lost all the communications to

the camera body = it became totally

manual, hence very difficult to sell.  

So, the boss resorted with a pretext as the

lens got the particular  number, I ought to buy.  😀

I don’t mind to have a Leiz lens, anyway in a collection, I have Leica R and Leica C,

and to have one more lens wouldn’t create any trouble.   And my Canon 5D is an

extremely capable camera which can be used with any lens.   THOUGH, Leica is a

notoriously awkward camera company.  = All the system was designed to be unique,

therefore the everything has to be genuine Leica made.  So, even just like a filter = this

lens got a screw size in odd 48mm.  ( Standard filter size is  46mm, 49mm, 52mm, etc.)  

In order to use a filter on this lens, a user has to buy a lens-hood which can hold a filter,

and only  special series filter can go into its gap. —– you might have guessed,

they comes with an extortionately high price ! 

A poor man like me can not afford to buy.      So, the solution is ……… if no matching

filter is in the market, why not to make one myself.

Outer diameter of the lens top is the same as 49mm filter though the internal

screw is for 48mm —– So, I scraped-off the male screw of 49mm filter, down

to 47mm.   Then this filter ring was glued onto the lens top.

So that, the filter size of this lens was converted to the universal 49mm.  

(which even allow the use of humble Tamron lens cap.  🙂 )

(Further screw-on another filter doesn’t cause a corner cut-off. )

Impressionist’s Flower Photo (without Pink)

Those photos were taken on the same day of the Shooting Party.

Being as an impressionist (for one-day 🙂 ) = no botanical

observation or comment.

Till here all the photos above were taken using a Fun Camera’s Lens.

And those last three photos were taken by the Wide-angle

Double-density Pinhole on Canon 5D Mk-III.

Pink — Impressionist’s Pink !

In early spring when the sun is not strong, the flower has to rely on its

hi-visibility color = yellow to appeal to the insects.

But when the spring deepen with increasing  sun light,  flowers who got other

tactics such as sweet scent doesn’t need to rely on its visibility,  hence  free to

pleasure  with another color. —– Then the Pink become in fashion.  😀

Though, I’m not knowledgeable enough whether those Pink has any effect to the

human psychology. Why a young lady saw something naughty blushs pink (red ?)

or a glass or two drinks makes the cheek pink ?

My friends has been rather wondering, or even suspicious about my eyes or

mental condition if those fuzzy images were the symptom of poor eyesight or

a kind of drowsiness for some kind of intoxication.  😀  

Surely, drunken wouldn’t say “I’m drunk” and I think I can focus if I need.

Those photos above were taken by the lens from Kodak Fun Camera on 5D.

But this photo above were taken by the Wide-angle double-density Pinhole.

And this one is a normal photo as a reference

—– whether you feel boring or sigh of relief (at home).   😀

Shooting Party

Yesterday, I’ve joined a Shooting Party who had taken the photographic course

together many many years ago !

As they are living in the Greenwich area, party went to familiar

Greenwich Park.

I went there with my Fish-eye lens, 24~70mm Zoom and

I field-tested yet another funny lens from a Disposable-camera !

Fish-eye lens worked well as always.  🙂

And those pictures were taken by another fancy lens 

= Wide-angle Double-density Pinhole !

The lens (?) worked perfect for ” the Impressionist’s Photography”.  🙂

(May be I need to have costumed actor and actress ! )   😀

Easiest way to make impressive picture is —– take picture of grand subject.  😀

Lens from Toy-camera

——- (Photo above :  Left = the edge of the lens has been cut to put a LED illumination.)

On the market, there are many adapter lenses for a Smart-phone or Tablet camera

to take wide-angle or tele-photo picture.  And many people might have

experimented to put magnifier glass or even the interchangeable lens of a SLR on

front of a Smart-phone camera.  = Yes, the lens placed on front, affect the image.

——– (Photo above Left = With additional lens, small letters on a receipt

——– was magnified = looks very sharp.)

Though, in most of the case, any lens put on front, functioning like a close-up lens.

And only the concave lens (such as short-eye-sighted specks lens kind) could make

the image smaller = wide-angle effect but may not give you any sharp image.  

Yet still, they works well like as a close-up lens, even like a microscope.

The photos here shows the effect of a small lens put on the Tablet (Nexus 7).

The very lens came from a kind of toy-camera.

(Lens and the Image censer looks same to the £30  Security camera.  😀 )

Still, this lens can project the outside image to the 4x3mm size censor.

It’s mean, use this lens in reverse, the lens can pick up the image of 4x3mm

and projects it to the land-scape size. 

So, I mounted this lens on the top of  18cm  spray can,  same way as I did before.

——– (Photo here = Bird’s feather  x40  magnification)

Apparently, the lens got  6mm or so focal length and 180mm extension  (together

with camera’s 44mm flange-back) it can give  whopping  x40  magnification.

——– (Photo here = Butterfly’s wing again —–  x40  magnification)

(Though, I wouldn’t say, with such magnification, taking photo is easy at all.  

= image in the view finder is very dark and the depth of field is extremely shallow

= with slight movement, the image vanishes.)    😀  

—– Coincidently,  I found a collection of Butterfly wing’s photos.  It must be the

result of months, if not years of work (together with a lots of digital manipulation)

= still pretty impressive.

Cause of Broken Zoom

———————— (Photo above, Right — Note a clack in the white nylon gear )

Yet again, this is about the same broken Sigma Zoom Lens.

While examining the mechanism, electronics, I’ve been puzzling why

this lens was not working.   It seems everything are functioning. —– ? ? ?

—– Then I noticed, when the AF motor was connected to the battery

and rotating, focus mechanism only moves a little.  In both direction,

gears rotates only short time even though the motor was kept running.  

—– On the end, I discovered,  a gear connected to the motor has a clack, 

so, it’s loose from the shaft and slipping.

[]

In theory, it is easy to replace the gear like this, which is not expensive.  

BUT in practice, in order to access this part of the mechanism, the whole

lens has to be disassembled. —– Considering the time and the expertise,

just  change a small gear which cost (to the Sigma) may not be more than 50P,

still the service charge would be more than £100.  

= good second-hand would be even cheaper. 

[]

In my life, I rarely paid a service charge to the camera company.

 1) I don’t brake a camera.   2) If it started malfunctioning, I repair myself.  

3) If it was beyond repair, I disassemble and use it for experiment. (and have a fun !)  

4) Being as a technical writer, the service engineers are my good friend and to keep

cosy relation, camera company wouldn’t charge us.  (often, broken camera is a bad

news which the company want to keep it  in secret.  

And our feed-back is indispensable for them. )

[]

In principal, the Gear shouldn’t break, still, as I saw the broken gear like this

only  the second time, it is rare occurrence.  = it should be OK

= and if it happened on you,  you are extremely unlucky.  

Have a pint or two and blame the God.  🙂

B/W Photo

Well, not quite.  Never mind, it’s a sort of.

They are  x10 Macro shot. —– In order to have something significant image

out of bird’s feather, it needs to have  x50 magnification.

I still couldn’t figure out “How bird can make a egg” —– I mean

it’s technological aspects.

Not mention, How their Feathers were made ?

F-Aperture / Iris Control (2)

This is the up-date of the post with the same title before.

The temporally test circuit of the Iris control then has been made to

a proper board.  Still, where to put the battery hasn’t yet fixed.

(At moment the power was connected through the cables.)

To make the drive circuit of Iris control was rather simple (= Just put the

necessary components on a piece of strip board.) though, where to put the

Open-Close Switches gave me a headache.  —– Ideally, it should be inside of the

Camera or make the Camera’s shutter button function for the trigger of this Iris

control too.  (Asking too much !)    Or, alternatively, put the Iris Close Button

right next of the shutter button and press both of them in the same time.

—– On the end, I decided to use the Camera’s remote trigger switch.  

Remote trigger switch is double switch.    First half press activates the

auto-focus then deeper press trigger the shutter.  Though, to the hand made

macro lens, auto-focus switch is no use.   I decided to use this switch to close

the Iris, and put a change-over switch to select  either Focus or Iris close.

(The button to Open the Iris was put the back of Remote trigger.)

In this setting, Focus and Framing can be done while Iris was fully open,

then the press of button, first close the Iris then expose the picture.  

With a use of  TTL Flash-light, almost automatically a photo was made !

—–  a short coming was, as the trigger was made by Remote Switch in the

left hand, camera was held almost right hand only. = a bit heavy.  😦  

Still, the Camera in the free-hand, then just click the shutter and enable

to take picture is a great convenience.  🙂  🙂
