Flowers by Vibrating Lens — Retake

Well, this was the retake of the previous post. — Since I found the most of the

photos there got a blurr by a hand-shake not by the vibrating motor intended.  

So I tried again using tripod. (You my need to see each photos, click, enlarged

and check the Bokeh imposed on the highlight (= bright yellow flower) and 

the sharp details maintained on the low-contrast area (= green leaves etc) )

I think, you might be convinced now the effect and the feasibility of this technique 

though, the question of What for may remain.

—– may be purely my endulgement, loves of the soft image.    

I would say, why not. 

(99% of the art are utterly useless, anyway.)  😀

————————————————————-

PS: The Lens I used were Canon EFS 18~55mm IS-II, Tamron Zoom 70~300mm,

the homemade device I used looks like this.

Lens ID — EXIF or Selfy

On the previous post, in order to show the sample photo of each lens, 

I took a lots of sample photos. —– then, to compile and name them, 

I found a difficulties —not always I could tell the photo by which lens.   

The each file of the photo normally having EXIF data though, it needs 

to have the lens’ ID from the lens’ rom memory in other words, lens

got to be a dedicated type.  

Unfortunately, lots of my lens isn’t genuine or dedicated type, so that

there was no EXIF data (still, I have 10 genuine lenses from Canon

— other lenses I’m still using with converter, adapter may be 20 

 altogether ?)  therefore often I have to guess which lens it was.

 ( When EXIF said 0mm lens, 1/8 second and if ISO setting was 12800 

= it’s likely a pinhole ! —– On the end, I decided to take “Selfy” on 

a mirror or a photo of the lens itself to record which lens was used

to take its sample photo.

Incidentally this was the Wide-angle Double Density Pinhole. (clopped photo)

By  this, low-contrast, low-color-contrast test shot, some of them showed

that they were not suited for this kind of subject !

= still I got good chart to select each of them.

Soft Image by Lens Vibration

After seeing the results of Somerset House shooting, I realized that the

“Focus-Shifting Technique” may not suite for that kind

of subject. —–> Then, I should try the 

Camera  Shake or Lens Vibration.

 There was a  good sample in my past

 experiment.    (Though, to replicate the

 same, perfect effect was not very easy.)

So that, in this time, in order to give a good shake to the camera, I devised a

vibrating element (small motor with ex-centric rotor) mounted on the lens. First, I tried it with Sigma Zoom 28~200mm while mounting the motor parallel

to the lens’ axis.(Photo above left)   But together with an effect of the gravity,

lens vibrated simple up and down.  Therefore, I changed to mount the motor 

perpendicular to the lens axis. (Photo center, Canon EFS 18~55 mm Zoom.  

And the Photo right, Tamron Zoom 70~300 mm)  

= As a result, the lens vibrates much more complexed way

= making a blur every direction.  — Still, there was much more decisive factor

here = the Sigma’s Zoom was quite hefty size and the weight, in comparison to

the almost weightless Canon EFS ZOOM 18~55mm which optical unit must be

lot easier to be shaken. —– (Position of the motor or its direction, such as on top

of the lens or 4:o’clock, 10:o’clock position and the camera’s direction etc are

also crucial)  It was the matter of the balance between the vibrating force and the

inertia of the optical unit or the camera body = hell lot of complicated dynamics.

On the end, a simple rule was, that if it wasn’t good, change the position of

the motor and try again. 🙂

This is the same flower as before, but here by the Lens Vibration on the

Tamron Zoom 70~300 mm at 130 mm . —– check the photo clicked and

enlarged to see its original sharp details and the added soft blur.  

Then to have a comparison with previous photo by the Focus Shift.

I know, I’m doing a very destructive aggressive approach to the photography,

somewhat akin to a musician smashing his own instrument though, I’m not

doing this for the sake of Conceptual Blah Blah but simply to create 

aesthetically nice soft image. —- It’s a paradox Sir.  

And, I’m having a fun— a lots.   😀  

( I need to go back to the Somerset House again and a field shooting to prove

that those exercises are not for wasting the time.   Ha ha ha. )

Focus Shift (A)

Focus shift is a kind of the holy grail to me in the soft image photography

together with the camera vibration.   Since the images of both techniques

were affected by the three dimension or the depth of the subject, it wouldn’t

be replicated by a digital graphical manipulation or a soft filter.

(effect of filter appears everywhere flat, same as a graphical effect —

otherwise it needs to give days of manipulation, pixel by pixel.)

So that, I’ve been working for this quite a while, hence such as the lens

 in the photo appeared here long ago. (Lens was Canon FD 50mm F1.8)

A device I made was not so complicated electronic controller which takes

the signal of the shutter-open from the Flash-hot-shoe then to start the   

AF motor in the lens, hence focus-shift (from the pre-focused point.)

= in the effect, the resulting image has both focused sharp image and

 an off-focused, fuzzy halo around.   The beauty of this technique is,  

it is not rely on the lens’ aberration but the out of focus Bokeh, therefore 

it can be done with any focal length. (as long as I got such modified lens) 

(For another lens = “softness made by the vibration of the lens” = which

can be done with ANY = non modified lens, would become ideal.)

(Click and see enlarged photo — the sharp detail is still there. )

(The field report would be coming soon.)  🙂

Sweetest Cherry Photo (so far)

Those photos were taken by a lens came from a Tokina Wide-converter and

its converging part of the lens has about 160 mm focal length, I call it Tele-soft.

In fact this lens can have a quite sharp image when an Iris was placed and the

spread of the light was centered — otherwise, its F4 equivalent of optics

produces beautiful soft Bokeh.     As the lens was mounted on a bellows, it is

quite awkward to use still, it can easily make a good close-up image as well.

I hope you appreciated to see them.   

(Honest ?)  🙂

PS : I didn’t use any filter or PS digital manipulation at all

—– only clopped and the brightness was tinkered on Picasa free program.

Images from Southbank (B)

Well, they were the rest of shots of the day at Southbank by the

“Homemade Two Element Lens”

— (This Lens was for Canon version, but I got Nikon version as well.)    🙂

I think, this lens and its images has enough significance, say raison de etre.

Anyhow you don’t need to agree.  😀

(What this lens amazed me was, despite its fuzziness, it still shows good details.) 

[]

Images from Southbank (A)

Like a word “City” mean a specific area of London, adjoining the north of Tower

of London where a lots of Banks, financial establishments were concentrated,

a word “Southbank” having special meaning as the center of the art performance,

from the music concert to the art exhibition.  

So, I’ve been this area quite often, long since —– though, this time it was

nothing to do with their art but just a casual snapshot on the street.

The lens used was that “Homemade Two elements Lens” consisting with two

plastic lenses = one from Toy Camera and a specs’ lens for short-eye sighted.

—– I didn’t design the lens but that toy lens happen to be there and I just

stretched its focal length by placing a concave lens on front.

(made it as a Retrofocus type)

(The beauty of this lens is, there is no focus or Iris control = just click it !)

I don’t have much of intention to control the image.  I happen to be there and

the scenery was there.  (by the way, there was no PS kind of process but just clop.)

Anyhow, this lens happen to have this quality which I like very much. 

It’s a fun indeed.  😀

Magnolia-2015-(A)

Magnolia here must be a garden variety of Magnolia Kobus, its origin was a Japanese

“Kobushi” (こぶし）which has 6 petals.  But I don’t know the Garden Name.

In this post, the photos were taken by a homemade Lens on Tilting Bellows.

And if it was not fuzzy, it was done by the Canon EF Macro 100 mm F2.8.

I still like those fuzzy images.  🙂

Graduation — ? ! ! ! of the Kyoto Uni’

Photos from Japan. —– a guy said “If anything crazy happened, it’s in Japan”.

As a very decent Japanese, —– still I agree with him.  Those photos were not from

Cos-Ple or Carnival but  can you believe, it was the Graduation Ceremony in

 the Kyoto University.

 Yes, they are new Graduates, the top-brains in Japan.  So, they are not crazy at all.  

 It’s not a Halloween or Carnival but more like an act  of Manga or Anime

 = Typical Japanese culture.

Before Manga, Japan had Ukiyoe (Utamaro) tradition.  = This tradition was in the context

 of Kabuki Culture.

[]

This Kabuki derived from a word “Kabuku” (傾く) = inclined or twisted = Eccentric. 

Strangely you might thought, the very traditional, Shinto, Buddhists Feudal society  

under the Shogun / Samurai-Ruled society,  still having very exceptional tolerance

towards the Eccentric or even indecency. ( think, mass publication of “Utamaro” !)

So, to have a public display of very extravagant Kimono of  Lord Date etc, etc, or

show-off of Fire-fighters, even a Yakuza’s stunt was a part of the Japanese culture.

= So, why not to have a FUN at the Graduation Ceremony ! ! !

(You may mistaken that it was a display of Ego, but far from it,

If the person could kill-off the own Ego, he can become a cat = otherwise, how

the one could make oneself fool, on THE day = only once in the life.)

Lens Test on Cherry and Plum Blossom

Those photos were taken a while ago, the same day I took pictures of Daffodils.

(After this, there must be much better full bloom somewhere else though.  🙂 )

(photo above was taken by a Canon Fisheye lens)

And the following photos were taken by the Two Element Homemade Lens above.

The beauty of this lens was that there is no focus  😀   (Other than this lens,

rest of the lenses were used with the Tilting Macro Bellows for focus.)

And the following photos were taken by a lens originally came from a Canon

compact camera G9 = it was their zoom’s front element.

The lens was Epoxy glued onto a lens mount ring and a filter ring was fixed too.  

Unlike first two photos, those photos were (I think) Plum tree.

Next was a front element of a Zoom lens  (I don’t remember where it’s came from,

Canon or Sigma ?)  — The lens was fixed in a similar way to the other homemade lens.

Front element itself couldn’t eliminate the aberration. —– but this one showed

very strong Coma aberration — (if not a camera shake).  In most of the case,

good softness of the image was created by the Spherical  aberration  

= so, Coma aberration was not desirable here.

Strangely, this Coma aberration appeared somewhat in middle distance.  

And not much so on the close-up.

This one above showed no Coma aberration but the following one did  ? ? ?

I need to have more test.

Last one here came from a cheap Wide-Converter for a compact camera.

It got quite big diameter — hence the effective F-aperture is F1.6 !

 

I like the images from this lens though —– strangely, despite full open F1.6,

the back image was not necessary out of focus or dissolved into big  Bokeh.  

Anyhow, each lens got its own character = pros and cons.  🙂

Last photo above was again by the same Fisheye lens.
