Yet more Impressionists Photos (2)-B

With much of annoyance of the regular reader, I put yet another

fuzzy pictures — but with added “academic” ( 🙂 ) interest !

The pinhole which I’ve called 3rd version, used in the previous post

and “Quest for Fuzziness” post etc was the one gone too far, hence the

image has very little informations.  

So, I made the 4th version which gives less halation and a bit sharper image.  

(outer hole is still the same 1 mm though, the inner hole was much smaller.)

So, here is a comparison. (Photo above was by the 4th version)

And this was taken by the 3rd version. = Difference is too clear.

 Those white halation can be reduced by darkening  (shadowing) though,

by doing so, the color contrast also increase = higher color saturation.

This was the reason why the images in the previous post looked like

a copy of old cine-film.  (It is a contradiction, supporsed to be a soft image

end up with strong color.  😦  )

Outer 1 mm hole was made on the thin aluminium panel (from beer can)

though, the inner pinhole was made on the thin plastic (from a cap of yogurt)

therefore it is very easy to make another one in 10 seconds,

and thanks to the DSLR, the effect can be tested at once.  

So, the Pinhole photography suits for a DSLR camera and really a fun.  🙂

(Especially in the case of Canon DSLR —–

Nikon needs to have Non-CPU lens set-up. (See the end of the Post)

—– I haven’t tested with other camera though)

Yet more Impressionists Photos (2)-A

The pictures in this post were also taken by the 3rd version of  

Concentric Double Density Pinhole which was the same one I used

for the previous post.  And the one giving the most drastic Bokhe.

Outer hole is 1 mm though the center Pinhole was comparatively large and

the material filling the gap is rather clear plastic. (it was a cap of yogurt .  🙂 )  

So that, it wouldn’t give so much details of the subject.

So to say, they are somewhat the equivalent of rough oil paintings by large blush.

So, the use of this Pinhole is a matter of the taste and the subject.

= Sometime it creates nice picture but not always.  😀

Yet more Impressionists Photos (1)

I guess, to the regular reader who followed past few posts, those photos must be

looks very familiar.   Yes, they were taken by the Concentric Double Density

Pinhole but this time it was by the (say) 4th model.   (In fact I don’t know

whether it was 10th or 20th —– I’ve tried so many minute variations.) 

Still, this time the diameter of outer hole was smallest 1 mm and the image was

a bit sharper than the one on the post “Quest for Fuzziness”   🙂

They may looks the same though, where “Fuzzy enough, but still show

the identity of what” lies somewhat critical.  😀 

When the picture become more and more like a painting, it’s need to

have “likely stage-up” — like this picture, it may need to have

a man and the dogs (if not a peasant) near the foreground.  🙂

A Field by Homemade Lens — (1)

Well, the lens what I call “Homemade Lens” has first appeared here as

the  “Lens from Toy Camera” and then having had additional front element,

it became to the “Two element Retro-focus Lens“.

In fact, the additional front element was a concave lens from my

broken specs. (Photo above: Left)    Then, proper optical lens came from 

HOYA Optics.   And finally I properly mounted that optical lens onto

Canon EF Mount adapter, using  67 mm filter ring. —– But, to put

the main lens (from Toy camera),  I mounted it 10 degree tilted forward,

since this lens has no focus adjustment, tilting the lens would give

a kind of Pan-focus effect. (Photo above: Right)

Still,  the images were the good old Impressionistic fuzzy image

which I’m very fond of.  🙂

What I like the most of this lens was,  it’s small size,  good general wide angle,  

no need to bother focusing,  shows enough detail of the subject but

not too much,  with good fuzziness —– and above all,  it cost nothing !

It is really a lazy Sunday Painter’s best companion.  = just click a camera,  

it automatically produces the paintings in mass scale !    😀

So, a knuck to have a life contented is = don’t ask too much.  Be contented.  

Ha ha ha   😀

Riot of Flowers (1)

The photos from the same flower patch and by the same homemade lens.

The different tone was created by the combination of  White Balance in

the camera and a digital adjustment in the PC. 

I like those photo’s  Opal like tone.

Hot, Hot — Do something !

After the Summer solstice, the room temperature climbing up and up.

—– I think I wrote a story before, a comparison of two different approach to

deal with a summer heat in Buddhism. = The one said

 “Sinto wo mekkyaku sureba, Hi mo mata suzushi”

(When you negate the mind and the thinking, even a fire could be felt cool)

And the other “Atsusa no natsu wa ase wo kaki, fuyu wa chizimi-agaru”

(Get sweat under the summer heat, and shiver in the winter)

—– The former was a typical attitude in the Hinayana Buddhism and the

later was the Mahayana Buddhism.

I think, the both are correct —– for them.  Please carry on.

= It’s not my business to argue with them as they are not on front of me.

—– I’m facing the heat in my room. —– Of course, I can escape and go out 

though, my PC is here and I have to do something on the Net. = The trouble is,

since I’m using an Internet Dongle to connect, the Dongle get hot.    And as the

room temperature nearing to 30 degree, the Net-connection is getting slower

and stated to say “Connection timed out” “This page is not available”. 😦

[]

In most of the case, trouble or malfunction in the electronic devices were

caused by the overheat.   Any mistake such as wrong polarity, over current,

over voltage, all resulting overheat and burnt-down (of some area or inside of

a chip).  So, the heat management is a big issue in the electronic circuit design,

which is parallel with the issue of “Low power consumption” —– though, the

situation is always the same. ( 10A current on 1A device cause overheat, and

10mA current on 1mA chip will blow them off).   And the devil is, when they get

hot, the current increases = more current more heat = Thermal-runaway.

[]

Funnily enough, even this extremely advanced technological age, when the

fore-front of science is dealing with such as almost invisible Gravity Wave still,

the way to deal with a heat isn’t different from 100 years ago. = Hoping the heat

would disperse (hence, lower the temperature of the area) through heat

conductive material (include the air).

( To generate the electrics out of heat, hence take the heat away, seems a good

idea though, it’s efficiency is less than 10% = 90 % of problem is still there. 🙂 )

—– So, to against a problem of Hot Net-dongle, my solution was “as advanced

as the fore-front of the technology today can offer” = disperse

the heat through a heat-sink to the air.

Photo Left : Disassemble the Dongle.

The Centre : Put heat conductive paste on a metal part of the Dongle

then place a heat sink over it.

Photo Right : Place the SIM card in position and clamp all together.

—– It’s working perfect.  Heat sink is getting warmer, mean dispersing the

heat from the dongle and as a result, the Net-connection got much faster. 🙂

(So far so good. —–  In case, if small window appeared saying “SIM card

invalid” etc, it was caused by the card was not properly slide-in  ===>

Place the card again while mimicking the action to slide-into the position.)

~~~~~ So, have a cool Net surfing.    🙂

Cosmos

In that “Instant Flower Meadow” I found the Cosmos !  

— You may wonder why it makes a news ?  = Cosmos is one of the most

common (wild)flower in Japan, especially in a late summer, even though

it came to Japan about 120 years ago.   (It was originated from the Mexico,  

and taken to the Spain about 230 years ago then spread to everywhere.)

But, in here I’ve  seen  the Cosmos only handful times, and this is the one !

(= It’s a good question why Cosmos got out of favour in England. )

Still, as it spread to the wild in Japan,  if you see a field or disused land, 

the chances are,  you will see either  Cosmos if not Susuki (You may not

think, Susuki is a Flower though)  otherwise a bush of  Yellow rod.    

(Strangely you may think,  that notorious Japanese Knotweed is not

spread in Japan. —– Obviously, they like the England more.   😀 )

When the Cosmos fills a field, they do literally end to end.  

And they are as toll as 1 m, 1.5 m or even taller.  

And this  kind of flower meadow was what I remembered as a child.

(So the photo above shows how the Cosmos field looks like in Japan

—– Photos from Maki Yamamoto’s site)

Their variation of color is from white to deep pink. — There is

also yellow one but, we don’t call it Cosmos.   🙂

On the end of the summer, under the dark blue sky and be in a 

Cosmos field, which seemed to stretch as far as I could see, and

the fragile Cosmos are trembling in the first wind of Autumn.

The field became an Universe. (= Cosmos !)

—– was one of my Proto-image with nostalgia.

(A burnt down city, thanks to American Bombing, Tokyo was

almost a wild field then. —– it’s mean, lots of flowers survived the fire, or

scorched land was quickly covered by the plants from surrounding area. )

 So, for me, the flower photo is not just for a  fun to the eyes, but

a clue to trace back mental landscape as well.

(That’s why they are fuzzy.  🙂 )

—– 

Photos here were taken by the Two Element Homemade Lens

(with or without Extension Ring) on Canon 5D Mk-III

Meadow Flower – (2)

Yet another photos from the same flower patch as before.  

And this time, I used the same homemade lens and the Zeiss 85 mm F1.4 lens.

On the photo, if the back ground image was not completely out of focus in a Bokhe,  

such as this one and the top photo, they were taken by 2 element homemade lens.

Other photos, which got strong Bokhe in the back ground, like this one,

it was taken by the Zeiss 85 mm lens with  F1.4  aperture setting.

Not only it is a short telephoto  85 mm,  its extremely bright  1.4 F-aperture gives

very shallow depth of field —– yet still, the image in focus has pretty good details.

(That what this lens was famous for)

The photo Right is in fact the part enlargement of the Left photo.

Likewise, Right photo was a pert enlargement of the photo Left.

When this 85 mm lens was used on the close-up distance, it shows very

soft Bokhe due to the increased Coma aberration, which I like very much. 

Stopped down to a smaller F-aperture, hence increase the depth of field,

photo became like ordinary photo.  🙂

Still, which way to chose is depend on the purpose and the taste.

My original image of the wild flower meadow was in my vague child’s memory,

when the flowers were taller than me, and it was far more than 60 years ago.

There shouldn’t be the same clear images, therefore,  I don’t need to see

the images from a catalog  of a garden-center kind.

(And, I do no longer dealing with the reference book publisher.)

Scissors’ Sorcery

Yet more puzzle on the previous post was that joke

” Scissors working on to cut a hole by itself”    🙂  

Nobody would believe it though, it looks, the scissors are flying in the air.

Has Scissors image been added onto a photo of the Tape using  PS ?

And has shadow been created to make looks, the scissors in the air ?

—– Yes, some of the people are pretty good at PS and may be manage

to do this kind of sticking job in 10 min.

 

 But I’m also a sculptor —–

 I rather like to spend the same

 10 min to twist a wire instead of

 sitting on front of a PC.  

Actuary, the scissors has been glued to the wire and held on to the position.   

Same idea to suspend a  “Levitating Guru”  in the air,  and quite common trick

among the photographers. =  So, this is yet another reason why you should

see the photo with a pinch of salt. —– Photo lies.  😀

Still, to make a photo to trick, is nothing but a pleasure of the photographer.  

= It’s really a fun.

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.)
