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 !

Mug shot (2)

Mug'B(1)-DSC09827

Yet another collection of Mag lens images taken around the Oxford street, London.

Mug'B(2)-DSC09830

Sony A7R’s AWB tend to give brownish adjustment when it has too much blue sky for alien lens.

Mug'B(3)-DSC09832

Mug'B(4)-DSC09831

Strangely this lens is pretty good to create 19thC townscape paintings like image.  May be Sony’s brownish AWB was contributing to this tendency too.

Only a trouble of this Mag lens is, its effect is sometime unpredictable.  😀

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.

What on Photography

What(1)-DSC_0461

Although it was a bit cropped, still this was a quite wide-angle view (18mm) of a morning sky, and this was more or less the view what we are actually seeing = in other words, this IS a faithful representation of the view = and that was what we expect to a photo.  —– So, the Photo IS a COPY of the subject, therefore if the subject wasn’t there in the first place, the Photo couldn’t exist neither.  And may be because of that, the Photo competition prohibit the Photoshopped photo.   Photo has to stay as a faithful secondary image of the subject.

What(2)-DSC08529

And this is the image of the same sky, taken by the other camera at about the same moment of the photo on top.

So, this is a tricky situation. This photo above may be seen to be an illegal image using a ready-made digital effect, so-called “Filter” such as in a smart phone.

What(3)_Photos

But this is the natural character of the lens.  From the common sense, this images may not to be regarded a Photo still, this IS the image, straight out of the photographic device / camera.  (Downsized to 1200x*** and collaged by Picasa in my XP laptop)

What(4)-DSC08525

What(5)-DSC08521

They were the images out of Sony A7R with so-called Helicoid (B) lens. —– If the photography was a mean to express oneself, those photos may have my feeling which evokes much deeper into your subconscious.  And they were not by the ready-made effect but only one of the kind in the world. (Whether you like it or not.)   😀

Helicoid Lens (B)

Helicoid-B(1)-DSC08508

Helicoid Lens (B) is a sister of (A).  Both came from the same Sony Zoom lens and I’m using the same size helicoid which I got from China.

Helicoid-B(2)-A09A7721

So, this 18~200 Zoom lens became the SZ lens and the Helicoid A and B.  Well done.

Helicoid-B(3) -004

Lens was tested while temporally fixed on the camera using plastic pate, such as whether the lens should be used reversed or not, and with smaller Iris etc. (Photo middle) In order to adjust the infinity, lens was fixed on a M42 to M39 adaptor ring on the M42 to AI (Nikon) mount adaptor. —– after the infinity point was found, the position was fixed with super-glue. (Photo right)

Helicoid-B(4)-010

It seems this lens was an aspherical as the funny shaped reflection on the surface suggests. (Photo left)  This helicoid extends from 17mm to 32mm and the Lens which got about 35mm focal length can focus from infinity to 15cm close-up.  And the calculation from the exposure reading, the brightness seemed to be F2.2.

Helicoid-B(5)-005

Though, this lens is having very strong aberration. ( Astigmatism ?) —– same as the Lens (A), the center wasn’t too bad but image quality was one of the worst = which I appreciate a lots.  😀     (It’s so rare to find this kind of image in the photography because, nobody design the lens like this for sale.)

Desktop5

(Photo here above, Left was the (B) lens in its finished looks — looks cool isn’t it ?   😀  And the right showed the Lens’ closest view, which showed its softness for comparison.)

For impressionistic fuzzy image, the poorer the lens quality, the image looks more interesting. (I think / and that was where Pinhole Photography stands) —– strangely, the close up image was rather sharp. (I mean its center was) (Photo right)  —– Whatsoever, I’m quite happy with its outcome.   😀

Helicoid Lens (A)

Helicoid Folder(1)-DSC08423

While hibernating in the winter (because, I can’t go ski kind, let alone climbing the mountain, = still have to do something — I made yet another homemade Lenses. (this time using a focusing helicoid sold in the net.)

Helicoid Folder(2)-003

In the political stance, I should re-use other old camera’s lens barrel kind though, they may not come when I want.  So, I bought some focusing helicoids from China such as 12~17mm, 17~35mm, 36~90mm, mostly M42 fitting.  (M42 rear mount / Pentax screw mount can be easily converted to Nikon, Canon, Sony-E with a simple (and cheap) adapter.)

Helicoid-B(2)-A09A7721

And the lens I used was came from broken Sony zoom lens. (In the center of the photo above, two of the small lenses)

Helicoid Folder(4)-001

So, the game starts = how to fix a small irregular shaped lens to the helicoid.   In here, cut a card-board paper to the shape (Photo left) and mount into an empty filter ring (Photo middle) — and 52mm filter ring was mounted to the helicoid. (Photo right) = to test and check if the infinity focus can be made. —– (this approach failed)

Helicoid Folder(5)-002

And in here, another lens was temporally mounted on a helicoid with soft plastic patty (Photo left) —– Photo middle showed the lens on the previous photo was screw mounted to an aluminium ring which was epoxy fixed on to the 52mm filter ring, and to the helicoid, then to the camera body. (Photo middle and right) —– (For clarity sake, those photos were taken before the mat-black paint was applied

Helicoid Folder(6)-00

This lens, with about 65mm focal length has an Iris ! —– though, the image made by this lens was too bad (except pretty good center) and the effect of the Iris was not much help.  😀

Helicoid folder(7)-Fullmoon-31-01

So, they are the images. (Looks hopeless coma aberration)

My attempt to make homemade lens has been having funny paradox, while making the lens DIY, the image quality was just fuzzy and poor, —– yet still, I’ve been trying to make it somewhat usable. —– ? ? ?    Then the “Enlightenment” came which was “Why not”  It IS the nature of the lens = bad lens makes bad image.  What’s wrong ?  The top photo here was made by this, Helicoid Lens (A) —– I think, this bad image was not too bad.  I like this painterly effect.  Don’t you agree ?  (It seems, the Japanese Zennists are visiting here.   So, those “Play with lenses” are also the demonstration of the “Mind game in Zen”=  “liberate yourself from a stucked mind” “Why not”    Ha ha ha.   😀 )

Meadow by Twisted Lens

Twist Meadow-1-A09A5796

This was the first field test of the so-called

Twisted Lens = Two convex lenses stacked on a bellows.

As the lens was on a bellows they were easily

re-positioned = so, the effect of blur was adjusted.

Twist-Meadow-2-001

Twist-Meadow-4-001

Twist-Meadow-3-001

Twist Meadow-7-A09A5782

Twist-Meadow-5-001

Twist-Meadow-6-001

Twist Meadow-8-A09A5791

Twist Meadow-9-A09A5763

As the lens was on the bellows, they were rather awkward

to use, nevertheless it managed to produce the photos.

You might wonder why I fuss about such fuzzy images =

The reason is, in our eyes we may not seeing sharp clear

images — they might be the brain re-constructed image.

(Remember, we never see straight line with rownd eye balls

— straight line IS the re-construction in the brain) 

That’s why we are surprised and impressed by the sharp

clear photos, same as when we see a detailed close-up

photo of an insect which we can’t see otherwise.

Moving or shaking

1-A09A5432

To create focus-shift soft image, it is nesessary to

use a slow shutter speed = in consequence, pictures

easily get bluured —– don’t worry, bluured or

shaky picture is still the pictures.  😀

Anyhow, I know, nobody would complain. 

In fact, to anybody, it’s not a matter at all.  

Ha ha ha   😀

Cherry Cherry – 2016

CherryC'16-1-A09A5196

Those photos were from the several Cherry trees,

probably the last cherry photos of this year.

CherryC'16-2-A09A5177

CherryC'16-3-A09A5173

CherryC'16-4-A09A5171

CherryC'16-5-A09A5192

CherryC'16-6-A09A5191

CherryC'16-7-A09A5178

CherryC'16-8-A09A5176

CherryC'16-9-A09A5184

Lens used was that modified Tokina-Wide-Converter

with bellows on Canon 5D Mk-III.

—– Don’t you agree, £1 junk from an Odds n’ Ends box

of a Camera shop wasn’t too bad.  😀

Cherry by Soft Lenses

1-A09A5079-Gaudy

The photos here were taken from the same Cherry tree as

the previous post.   (As they are not plain 5 petals flower,

this is not Somei-yoshino) 

The softness (?  Blur) on the previous post were created by

the Focus-Shift = focused image and the out-of-focus image

were mechanically superimposed on the shot. — But here,

the softness was caused optically by the lens’ aberration.

= Those first 4 photos were taken by the homemade

single glass lens = nicknamed “Gaudy lens” .

2-A09A5063-Gaudy

Among my homemade lenses, this is the most useful,

easy to use lens.

3-A09A5072-Gaudy

You may say, the aberration of this lens is too much

though, this is what I wanted.   🙂

4-A09A5075-Gaudy

5-A09A5094-Tokina

Above those two photos, you can see the type of

softness are very different.  = The photo above and

the following 3 photos were taken by  the modified

(front diverging lens was removed)

Tokina Wide-Converter.

6-A09A5088-Tokina

7-A09A5086-Tokina

8-A09A5097-Tokina

Regardless the technical blur blur, all about

the photography (or any art) the matter is the

end result = if it is good, it’s good. 

Nothing else.   😀

(And when the result was the same, the cheaper

the cost is the better.)
