Bokeh (from the Japanese boke ぼけ, "blur") is a photographic term referring to the appearance of out-of-focus areas in an image produced by a camera lens.[1] Different lens bokeh produces different aesthetic qualities in out-of-focus backgrounds, which are often used to reduce distractions and emphasize the primary subject. The effect itself is the circle of confusion, an image of the aperture convolved by the image itself.


Mike Johnston, former editor of Photo Techniques magazine, claims to have coined the bokeh spelling to suggest the correct pronunciation to English speakers,[2] replacing the previous spelling boke that derived directly from the Japanese word for "fuzzy" and had been in use at least since 1996.[3]

The term bokeh has appeared in photography books at least since 2000


Although difficult to quantify, some lenses enhance overall image quality by producing more subjectively pleasing out-of-focus areas, referred to as bokeh. Bokeh is especially important for large-aperture lenses, macro lenses, and long telephoto lenses because they are typically used with a shallow depth of field. Bokeh is also important for "portrait lenses" (typically medium telephoto — 85–150 mm on 35-mm format) because the photographer would typically select a shallow depth of field (wide aperture) to achieve an out of focus background and make the subject stand out.

Bokeh characteristics may be quantified by examining the image's circle of confusion. In out-of-focus areas, each point of light becomes a disc. Depending how a lens is corrected for spherical aberration, the disc may be uniformly illuminated, brighter near the edge, or brighter near the center. Lenses that are poorly corrected for spherical aberration will show one kind of disc for out-of-focus points in front of the plane of focus, and a different kind for points behind. This may actually be desirable, as blur circles that are dimmer near the edges produce less-defined shapes which blend smoothly with the surrounding image. Lens manufacturers including Nikon and Minolta make lenses designed with specific controls to change the rendering of the out-of-focus areas. These lenses include the Nikkor 105mm f/2, Nikkor 135mm f/2 and the Minolta, now Sony 135mm STF.

The shape of the aperture is commonly believed to have a great influence on the subjective quality of bokeh. When a lens is stopped down to something other than its maximum aperture size (minimum f-number), out-of-focus points are blurred into the polygonal shape of the aperture rather than perfect circles. However, this is only apparent when a lens produces undesirable, hard-edged bokeh. Some lenses have aperture blades with curved edges to make the aperture more closely approximate a circle rather than a polygon. Lens designers can also increase the number of blades to achieve the same effect. Canon's EF 85mm f/1.2L II lens (often used for portraits) is an example of an almost circular aperture diaphragm.

Bokeh can be approximated by convolving an image with a circular box blur kernel. In general, a particular look can be achieved by convolving with a kernel corresponding to the image of an out-of-focus point source taken with a real camera. (Diffraction optics may alter the effective shape of the blur.)

The other characteristics of a lens that cause it to produce pleasing bokeh are complex. Some lens designs are known to produce a certain kind of bokeh, but most photographers do not fully understand how the lens design influences bokeh; they merely note whether a lens produces results that please them. For example, mirror lenses produce a "doughnut" bokeh that is generally considered unpleasant.

Unlike the Doisneau photo, the Eisenstaedt kiss does not appear to have been staged.

This picture by Robert Doisneau is perhaps one of the best known images in photography and one of the best selling ones as well.

Would you believe it that it was not a snapshot but it was staged? And there was a huge case with people claiming to be the kissers and asking for money

Another famous image of a kiss is Robert Doisneau’s “The Kiss by the Hôtel de Ville,” taken on a Parisian street in 1950. Alas, the image — considered one of the most romantic ever taken and widely reproduced since 1986, when it was first printed as a poster — has a less happy story. As Hélène Fouquet reported, in 1993, a former actress, Françoise Bornet, emerged from anonymity when she sued Doisneau for $18,000 and a share of the royalty in the image. The case was dismissed, but during the proceedings Doisneau revealed that the scene had been staged. Doisneau died in 1994. Ms. Bornet sold her original print of the photograph for $242,000 at an auction; the rights remained with Doisneau’s agency.

I took these pictures in Market Street, Manchester (just outside the Arndale centre), summer 2007.

I just stood and watched gaping as this old geezer sat and played the flute for a prolonged period of time without wasting a single puff of his cigarette. I thought it not only redefines the concept of addiction, but the concept of avarice.

Pity I only had my mobile phone with me and the quality of the pictures is not that good.

This is a photograph I staged with the help of a friend.

Her gaze is big, deep, clear and loving. I am very happy about this picture.

I loved the expression the mood and feel.

I find this picture funny in a weird sort of way as it draws indirect parallels between the work of art and the woman. From an exhibition of the students of Vakalo - School of Art & Design.

Photoshop was used in order to add the flower. I find that the colours of the flower happily match the ones of the girl. And, of course, the girl is simply beautiful! Picture shot in Paxos.

This was shot in the studio of my photographer friend Katerini.

Taken in Koh Samui, Thailand. Very slow speeds were used (2-3 seconds) and the camera was hand-held.

I love the poetry of these shots.

An impressive phallic rock formation in Koh Samui, Thailand with some extra... jizz. A truly orgasmic experience.

Monks in Thailand

This picture was taken in Bangkok.

And this one in Chiang Mai

Thai monks watching a parade.

Hey, what do you think these monks are watching with such intensity (behind the walls of their monastery in Chiang Mai)?

It is a very titillating parade:

This is from Doi Ithanon temple in Northern Thailand. I loved those big round balls and the long straight shaft in the middle and I played with them.

Who says elephants are not good at basketball? Even Michael Jordan would envy this lay up. Taken in Koh Samui, Thailand where elephants have their own local basket ball league.

A picture taken in Sukothai, Thailand with just a tad of naughtiness...

Colouring and distorting the photograph using various filters and effects.

Shooting photographer Andreas Katsikoudis and Ioanna in a playful photosequence.

There are portraits of my friend, artist, architect and interior designer Manolis Iliakis.

The one that personally moves me more than any other, is the one shot in a church, where the spiritual qualities of the model are quite successfully emphasized through the gaze and the warm colours:

From a fashion show at Booze 9/12/2005 by Poupée (Χριστίνα Μαθέα).

My absolute favourite is the following picture:

These are some photographs I took at Dimitris Dasssios' brilliant show held at Zappeio area and part of the 4th Hellenic Fashion Week Show - October 2006. I must confess I really liked the clothes, the models and the whole presentation. One of the best shows I have ever been to.

Μια φωτογραφική διαδρομή της μεταπολεμικής Ελλάδας με πρωταγωνιστή το αυτοκίνητο παρουσιάζεται από τις 3 έως τις 31 Δεκεμβρίου 2007 στο «National Theater – Athos Bulcao Gallery» στη Βραζιλία.

Η απελευθέρωση, τα Δεκεμβριανά, ο εμφύλιος, οι πρώτες προσπάθειες για την αποκατάσταση του κατεστραμμένου από τον πόλεμο συγκοινωνιακού δικτύου της χώρας, καθώς και προσωπικότητες και αρχηγοί κρατών που κινούνται με αυτοκίνητα στους δρόμους της Αθήνας παρουσιάζονται στις 55 φωτογραφίες τις έκθεσης που έχει τίτλο «Αυτοκίνητα 1944-1964».

Οι Βραζιλιάνοι θα έχουν την ευκαιρία να θαυμάσουν θέματα τόσο διαφορετικά όπως συλλαλητήρια, νικήτριες καλλιστείων, το Ράλι Ακρόπολις, η επιστροφή του αρχιεπισκόπου Μακαρίου από τις Σεϋχέλλες, η Ford που σκότωσε τον Στέφανο Σαράφη, η περιφορά της εικόνας του «Αξιον Εστί» με μια ανοιχτή Plymouth στους δρόμους της Αθήνας, τα οποία έχουν ως κοινό παρονομαστή τους «τέσσερις τροχούς» ενός οχήματος.

Πρόκειται για μια παραγωγή του Μουσείου Φωτογραφίας Θεσσαλονίκης που παρουσιάζεται στο πλαίσιο του φεστιβάλ φωτογραφίας Foto Arte Brasilia.

Οι φωτογραφίες της έκθεσης, των Ευριπίδη Μάρτογλου, Δημήτρη Τριανταφύλλου, Δημήτρη Φλώρου και Δημήτρη Φωτεινόπουλου, προέρχονται από μέρος του αρχείου του πρακτορείου των «Ηνωμένων Φωτορεπόρτερ», το οποίο ανήκει στον Νίκο Ε. Τόλη.

There is a big debate going on as what is better. I am sure that most high-end DSLRs (of 8 megapixels or above) give on the whole much better results than 35mm films in most areas. Below you can fins some links which explore this issue further

What is a photoblog?

A photoblog (a.k.a. photolog or phlog) is a form of photo sharing and publishing in the format of a blog, but differentiated by the predominant use of and focus on photographs rather than text. Photoblogging (the action of posting photos to a photoblog) gained momentum in the early 2000s with the advent of the moblog and cameraphones.


There are 3 basic types of photoblogs. Photoblogs on individual domains, photoblogs on blogging services such as Blogger that were designed primarily for text content, and photoblogs on photo specific blogging services such as Fotolog or Flickr.

The dynamic nature of blogs and photoblogs compared to static sites means that blogs require some form of content management system (CMS) rather than being built by hand. These content management systems usually provide the photoblog's authors with a web service that allows the creation and management of posts and the uploading of images. The CMS delivers webpages based on the data entered by the photoblog author. Access to photoblogs is usually unrestricted and available to anyone with internet access and a browser.

Some existing blogging CMS have been modified by the use of add-ons/plugins (and sometimes core code rewriting) to enable the transistion from text blogging to photoblogging. As an example, a photoblog author might limit his blog to display a single entry per day (as opposed to several entries which is typical for text blogs) and he might put thumbnails in entry excepts to provide archives that display images instead of text snippets. Over time, developers have begun to write purpose-built CMS just for creating photoblogs. Additionally many services specializing in hosting and displaying images such as flickr and fotolog have APIs that allow other blogging systems to display their images giving the user many options as to the construction of a particular site.

The early days of photoblogging required some level of technical experience with setting up a webserver and installing or writing the CMS code for it (e.g. Pixelpost). Many photobloggers still prefer this option of running their own server, as this gives them full control over the display and functionality of their photoblog. However, there are now a range of photoblog hosting services available which provide ready made photoblogs in which everything has already been setup. This has made photoblogging more accessible to the layman.

I was just walking down Panepistimiou street (central Athens) at about 00.10 Thursday, 25 October and I witnessed a kiosk on fire. The copper was not very keen on me approaching further, as the firemen were on their way. Pity I only had my mobile phone with me.
