Screen shot by Soft lens (2)

Mag COPY(1)_DSC0028

I found this pretty image in the net.  The original was much sharper, rather normal picture.  When I took screen copy using my homemade Mag lens, in order to avoid a moire, I gave a bit of off-focus.  It was a character of the Mag Lens, when it was off focused, the image suddenly increases the aberration thus, the image become nice soft picture.

Mag COPY(2)_DSC0024

This image was not as much as off focused like the first picture. (Just enough not to see the screen pixel, hence neither moire)

Mag COPY(3)_DSC0027

Then give a bit more off-focus.  —– Isn’t this picture looks more sexy ?  (Shame, I was not the photographer to see the lotus flower in the first place)

I think, now you were convinced to appreciate soft image !

Need lens ?

Cyriacus & Julitta church 11

(Photo above by Gordon Cooper, Church Window, July 2018)

My friend cinematographer Gordon sent me the Photos he took on his holiday in the Cornwall.

While rest of us has been barely surviving in this heatwave, what a lucky guy, Gordon.  He sent photos while saying “Who need the lens” = In deed the photos were taken by the Pinhole which I made for him. —– Yes, exactly like us living without cloths, the camera can take a photo naked = without the lens.  With Pinhole.  That’s true.  I’ve been forgotten the Pinhole —– so, take them out and took some photos around.

Pin

(What I don’t like Sony A7R is, their AWB / color balance fluctuates a lot)

I got enough variety of Pinhole = this one was even fuzzier “Concentric Double Density Pinhole” = a smaller Pinhole inside of the other pinhole = create a void inside of yet another void = how can we ?.  (This is a physical and the philosophical problem.   😀 )

Pin

Need lens(4)-DSC09903

The advantage of the Pinhole is, (as long as the camera can co-op) we can take photo without bothering the focus. (= in any distance, image would have the same fuzziness which depend on the size of the hole)

So, the Pinhole convert the image into a constant pattern, almost like a paper cut-out.

And this is the comparison.  Those three photos were not Pinhole but by the Mag lens. Lens will make one focus = other than this distance, the image will be out of focus, which effect gives a feeling of the depth / three dimension.

Mag

This Mag lens image has the strong effect of the aberration together with rather messy out of focus bokeh.

Mag

On this photo, right amount of out of focus bokeh is giving a nice softness —– if this one was by the Pinhole, it would become rather messy image. = Pinhole is not necessary suit for all the subject. (better suit for bold pattern and that kind of image = in other words, for the some subjects, optical lens would make better image.  Needs lens !

Vest Pocket image on the 6×7 camera

Vest'P6x7(1)-A09A8379In the previous post, you might have seen the Vest Pocket lens’ image captured by a 35mm full size digital camera.  Though, the original size of the Vest Pocket camera was 6×9 (43mm x 65mm exact) —– so that, the image only on the cropped center wouldn’t show the full character of this 100 years old lens. —– (Strangely to say, don’t you agree this picture above looks like 100 years, even 200 years old painting ?)  

—– The fact, you must be noted is, 100 years ago then, the user of Vest Pocket camera seeing their picture contact printed on 6×9, card size B/W print.  Today’s reader of this blog can see the picture’s detail / sharpness easily enlarged, though there was no such luxury in old days = people just accept the picture made by the camera (with no focus adjustment).  As long as the picture showed the face looks like your boy, it was a good picture ! 

A funny story was,— there was a Photo-club in Japan,  namely “Vest Pocket camera appreciation club” (Ves-tan Club”/ べス単クラブ — Ves-tan stands, Single lens Vest Pocket ) of which the photo enthusiasts of the photo image made by the Vest Pocket camera was associated together.  And among the members, there was a special practice = use the camera while lens’ front hood which restricts the aperture smaller was removed (— See the previous post =  Lens was originally F6.6 but with the front hood makes it to F11). So, they appreciated the images with soft bokeh by the spherical aberration, the most.  In today’s standard, they might be branded “Otaku”  (It was almost like a religion, same to prefer the images made by the Canon or Leica lens than the Nikon, saying that the Canon shows the atmosphere / or taste (aji / 味) more, but the Nikon lens pick-up just clinical flaw of the skin.  —– mind you, this was the story of 40, 50 years ago.   😀 )  

Vest'P6x7(2)--004I mounted the lens on the Pentax 6×7 body using a camera’s body cap and tested its image character.  (You may say, 6×7 is not 6×9 though, don’t be too fanatic = it wouldn’t kill you anyway) 

Vest'P6x7(3)--003

(In order to mount the Lens unit to the body cap, an aluminium ring was cut out.  Because the lens has to be very close to the camera body, there was no space to put a focusing mechanism.  So that, the close focused image was made by adding an extension ring. )

Vest'P6x7(4)-A09A8359So, I took some photos on the 15 years old,  Fuji, Provia  ISO400 film — but exposed as ISO160 as I anticipated the film’s loss of sensitivity in time. — (Since, the lens was set to maximum F-aperture (F6.6) the image was pretty fuzzy on the 6×7 Pentax view finder too = rather difficult to see the definitive image.)

Vest'P6x7(5)-A09A8343

Vest@p6x7(6)-A09A8364

(Since the 100 years old single grass lens has no coating, image has a lot of halation as well.)

Vest'P6x7(7)-A09A8365

Vest'P6x7(8)-A09A8374

Vest'P6x7(9)-A09A8368

(Fuzzyness was created by not only its out of focus bokeh but by its aberration too.)

Vest'P6x7(10)-A09A8376

Vest'P6x7(11)-A09A8357

(In here you can see a lot of bokeh by the spherical aberration.= unlike the intentionally created bokeh of Helicoid Lens (A) or (B) kind, Vest Pocket lens’ fuzzyness looks more natural.)

Vest'P6x7(12)-A09A8381

So the painterly effect of this Vest Pocket lens looks rather subtle and looks natural. And the image has more atmosphere which gives more depth to the image too.  A depth of its image was induced by the emotional resonence (something like = I’ve seen this long time ago), not from the detailed data which will talk to the intellectual brain —– in fact, too much data in the image distract an emotional response, exactly like a noise in the music.

(Which the members of the “Ves-tan Club” most appreciated.)

Vest Pocket Lens on A7R

Vest'P(1)-DSC09764On here, the images of Vest Pocket lens from the field test.  (Give a close eyes to this photo and see how the details and rich tones are there ! —– by the way, the image looks a bit more greenish on iPad screen.)

Vest'P(2)-DSC09800

—– If the image looks fuzzy, the lens was fully open (F6.6).  (But mind you, the original Vest Pocket camera’s image was 6×9, therefore we are only seeing its cropped center here.)

Well, Vest Pocket lens on the Sony A7R was the camera who took those photos though, behind of those, there were many more minutely blurred photos, seemed to be caused by the wobbly lens structure.  Otherwise, some photos were amazingly sharp, considering that they came from such old single glass lens !  (And it would rise a very serious question, that is, the great effort the manufacturer spending to create 10, 20 elements lenses using ED glass etc, what sort of practical significance was made ? —– of course, unless otherwise, there couldn’t be such as 14mm F1.8 lens or 18mm~400mm Zoom etc etc still, —– ? )     In reality, often, those expensive technical samples were made for demonstration purpose and made only 100 or so to display in their showroom.  In contrast to the millions of  18~55mm plastic kit lens.  Funny fact was, even after the people was made to believe that “the Larger the Better” myth suddenly changed into iPhone camera. —– It indicates that, so-called fine sharp image might be just a formality nobody actually bother. )

Kodak Brownie camera and its Images

To bring the analog B/W image to show, its needs to make a paper print (unless we use the scanner and upload straight)  Unlike a color process, B/W print-making is not a kind of automatic mechanical process (even just to choose which paper and one of 5 contrast grade of paper to start, then where to burn etc etc) = lots of interpretations and intentions could bend the original concept. = (if it was only to  check  the quality of the lens or the images, it can be done by just looking close into the Neg’ —- though, just develop the Neg’ = the half century old Ilford film has jumped around and self-scratched by their strong carl, which was made by their own fate =  tightly wound on the narrow spool such a long time ) —– so, I show you the contact print here and forget the individual print at a moment. ( Despite such awkwardness, the B/W test shot showed quite consistent results — made me amazed a bit = So, don’t misjudge the Brownie from its humble looks = once they were the Darling of the era like an iPhone camera now.   😀 ) 

Brownie(C)(1)-5-003

(B/W contact print above = The film was 50 years old Ilford Selochrome ISO160 / Though, Exposure was given as ISO80 / developed by D-76, 1+1 / 11 min’ on 18°~23° )

Obviously, Brownie camera has no focus neither a good viewfinder (their aerial image finder needs to look-down from feet away = its mean, no eye-level shooting other than a blind-shot) so that, beyond the fun snapshot or memento pictures, it may not suite for critical “Creative” work. 

And this was the test shot by the 15 years old Fuji color film on Brownie camera — (400 ISO Fuji Provia seemed to retain only 200 ISO after 15 years) = still, looks pretty good aren’t they !

DesktopBrownie(C)Nun-5-007

On a casual shot of the Nuns Head Pub, I realized that the notice board was almost legible (Photo right — Did you notice heavy chromatic aberration on the man’s head ?)

Brownie(C)(2)-A09A8225(do not ask the quality of the digital copy —– it was just a DSLR copy by a flash light behind the transparency.) (—– I’ll make more properly digitized photo = when I found white perspex board which  I used before)

Mag-BrowBrownie(C)(2B)-06-18 Folder

I show you the comparison, The same Brownie photo and the other by Sony A7R — It is obvious, the disadvantage of the blind-shot. (In fact, the Sony’s shot was made next day)

In this situation, not only to test the lens on 35mm DSLR,

Brownie(C)(3) -620 film

(Those photos here were Brownie lens on the Sony A7R.   Not too bad mean, not brilliant —– on the Bokeh test, this lens showed halo together with chromatic aberration = blue fog on the edge)

I mounted the Brownie lens on a 6×7 SLR (Pentax 6×7) with the additional focus control to see how this lens could perform. (Since, only the lens was taken out ( leaving the shutter mechanism behind, which has been acting as a smaller F-aperture as well)  now the lens is effectively F8 = As the peripheral of the lens which is not the good center part, the image became lot more foggier.)

Brownie(C)(3)-5-002—– This 6×7 body was a spare-body when Pentax 6×7 and  Hasselbrad was my main camera.  I’ve sold those mid’ format cameras when I had a Court battle.  ( I fought for 3 years battle without a lawyer, and in the Court of Appeal, stand against the President Judge who tried to white-wash the case) — It was my same stance “If Canon can do, I can do it too = If the English Lawyer can do, why not a Japanese” —– But, about the camera, nobody wanted to buy this body which has no viewfinder, so that it remained in my hand = still its works as a big camera.   😀  —– On this occasion, I made a waist level view finder using juice-cartoon ( = good to be a sculptor as well)   😀   

Brownie(C)-Pop-5-006

(So, those photos were a bit more properly digitized 6×7 images = Copied on a white perspex, with TTL flashlight behind.)

Brownie(C)Blu-5-005Those are the photos of Brownie lens on the 6×7 SLR. (for those macro shot, extension ring were added too)    (waist level finder was not easy to use = such as, to see reversed left and right in a vertical image ? — Where am I looking at ? )

Brownie(C)-Cow-A09A8231

(Brownie lens on the Pentax 6×7, shot on the 15 years old Fuji Provia film which were  Digitized by the Canon 5D Mk-3, like making a Copy )

Short Walk (B)

Short walkB(8)-DSC09273

Short walkB(1)-DSC09243

Those photos were another product of the same Short Walk (A), hence using the same homemade lenses Helicoid (A) and (B) on the Sony A7R.     While walking through the park, finding which flower is really a chance encounter, and how to capture it, while seeing the character of the optics and the shape of the flower, how to compose it, in which angle and the distance IS what all about the Photography.  In certain extent, it is a game or the match between the two personalities.  In Zen Buddhist term, we are living on the moment to moment life.   And to deal with the Person (subject just encountered) as if there is nothing else exists and nothing else to do is, so-called Mindfulness, and in this mind-set, there is no Ego.   So, this situation is a proof of the No-self or Anatman.   Yet still, in other stance, to see a subject as a subject might be seen as yet another Ego, therefore not aim the subject but to see everything as the everything may be a right view.   Though, in practice, the image of an ultra-wide angle lens clicked random is just a mess —– so, the question is, whether the Zen needs a nice answer ?    Or such answer itself is not Zen ? ? ?  —– Good question.   What a nice day ! —– Ha ha ha,  😀  

Short walkB(2)-DSC09268

Short walkB(3)--2018

Helicoid (A) lens happen to have an Iris, so that, by the depth of field control, flower showed a bit more details, still, take the image of Helicoid (B) (photo right) is a matter of the taste.

Short walkB(4)-2018

Both (A) and (B) lenses, its center of close-up images are amazingly good.

Short walkB(5)-DSC09267

Short walkB(9)-DSC09283

Short walkB(6)-DSC09279

Short walkB(7)-2018

Those two pictures were given a shake when the shutter was opened. (Don’t ask me what for — it’s only for a fun)

Short walkB(10)-DSC09294

Short walkB(11)-DSC09293

I realized that I don’t have many photos of the Blue Bell.  May be their flower is too common, yet only in a short period.  Still, why it makes the difference to the Cherry ? —– M m m ?  —– I might have an unconscious notion, that the Cherry is the Japanese but the Blue Bell is English.   But why ? ? ? —– May be because, I didn’t grow up with Blue Bell but with Cherry.   As the photography is a way of the Self expression, it became a kind of a biography.

.

Short Walk (A)

Short walkA(1A)-DSC09254

In deed, I haven’t have done a photo-walk a while. —– without a reason = IS a problem = just getting lazy.   So, bashing myself and went out with a camera and two lenses. (still, all in one pocket = that’s a beauty of the small homemade lenses. = Helicoid (A) and (B) lenses with Sony A7R)

Short walkA(12)-DSC09290

You may wonder what was a point to have those two lenses.   Ha ha ha, you are right.  Both of them are equally fuzzy lenses.  The differences were, —– if the fuzzy surrounding has Coma bokeh, it was the (A) lens.  And if it was with Astigmatism bokeh, it was the (B) lens.   Both for the sake of painterly effect which I like very much.

Cherry Cherry – 2018

Cherry cherry(1)-DSC09146

Since I put the photo of the first cherry, it’s already 3 weeks past.  They are still in full bloom though, the flowers started falling. The end of Somei-yoshino season.   (Then Multi petals cherry is coming.)

Cherry cherry(2)-DSC09140

So, this year’s Cherry pictures were made by “Helicoid-B” lens.  (One of the worst reputed lens ! = therefore in these days I’ve been using the most.   😀 )

Cherry cherry(3)-DSC09147

Without me shake even a single finger, the picture became almost trembled. ( = The technique to produce the paintary effect in the most economical way !     😀 )

Cherry cherry(xx)-026

Cherry cherry(7)-DSC09150

(Only the problem was that the image in the finder was too fuzzy to see the focus.)

Cherry cherry(5)-DSC09166

So, those two (three) photos were taken by a kind of normal lens = Tamron SP 500 mm Mirror lens. —— Somebody teased me saying “Can’t you take normal picture ?” “I leave that kind of business to the Phone camera user, otherwise no point for me to use bulky interchangeable lens camera”   😀

Cherry cherry(6)-022

Though, the Tamron gave me too pale color.  (May be I need to use Photoshop kind though, that’s what I hate most.)

What ? — OMG, it’s Cherry flower

Cherry-18(1)-DSC09083

On the street, I found a dropped Cherry flower.   —– ?    What ?   —– I looked up, OMG it was a cherry tree started to open the flowers.   Only few days ago, there was nothing.  It’s suddenly happened.  I picked up a dropped flower and a bud to bring back.

Cherry-18(2)-021

I put the flowers on the water in a lens cap.  And took pictures.  (After a while, a bud opened as well) —– It was a kind of my habit in these days, which was to make the photos for comparison = the photo left above was taken by Sony 30 mm F3.5 Macro and the right was by Helicoid-B lens.

Cherry-18(3)-5-001

So, this year’s first Somei-yoshino flowers were put next to the kitchen tap = In fact, this IS my photo studio.  (All the “Studio shot” in my Blog were taken in this “Studio” !    Another funny fact was — that all those homemade lenses were made in this kitchen work shop, and almost all of my sculptures were also produced in here.)  

It’s very simple, if we need to make, make it, or just do it.   There may not need to have any good-cause or theory or facility kind.  So, if you have a knife, you can cut.  With the same knife, you can cook as well.  If you can’t, you were just clinging an excuse of not to do or even worse you might be waiting somebody to push your back.   😀     (By the way, this is in deed the way of Zen = Zen need no cause or reason to do.  In fact Zen is to eliminate anything that kind.  Therefore Mushin (Mind of No mind) still, even a mind to think No-mind shouldn’t be there, = hence “Everyday’s Mind” (Heijo-shin 平常心). That’s why to able to be in the Everyday’s mind which is nothing special / peculiar  (is so ubiquitous as a dog shit) IS the Enlightenment.

Screen Copy by Fuzzy Lens

Hel-B-COPY(1)-DSC09007

The outside is still cold and not much flower, and, I’m not keen to take picture of cut flower = so, just took photo of a flower in my old post screen using very fuzzy Helicoid-B lens.

Hel-B-COPY(2)-006

When I try, I realized that the old screen of XP laptop makes moire pattern, so I changed it to iPad screen. (though, iPad screen makes the color a bit artificial)

Following 4 set of those photos, Left side were the original and the right photos were the screen shot. (All those photos came from Somewhere Net website —– I hope they don’t fuss about the copyright)  (If you Google, you may find the same very easily)

Hel-B-COPY(3)-003

Hel-B-COPY(4)-001

 

Hel-B-COPY(6)-004

Hel-B-COPY(7)-000

Ideally, I should take the original photo myself though, I’m no longer such keen —– (and neither the model herself keen to see dirty old man.  Ha ha ha.  😀 )

I think you may agree, we don’t need to see too much details of the girls.  We are not seeing the woman like an ological specimen.   In certain extent, the beauty of the flower is the same = We only need to feel its atmosphere. (If we go into the details of the flower, often they are rather grotesque. —– after all,  flower is the sexual organ of the plant. —– or, am I a sexcist ?)
