<p>Aproveché que el otro día estuve jugando con mi 50mm f1.8 para subir esta foto a flickr. Está tomada en Astorga, en una calle cualquiera, con una larga exposición (6s) y totalmente fuera de foco. La apertura fue de f1/4.</p>
<p>Me gusta particularmente por el efecto del desenfocado. Los pentágonos que se ven en la fotografía son en la realidad puntos de luz: farolas los 4 de arriba más intensos y el resto reflejos sobre coches aparcados junto a la acera.</p>
<p>Técnicamente estas figuras deberían ser círculos perfectos. Cuando un punto está fuera de foco se convierte en un borrón circular, así que estos puntos de luz debería ser igualmente circulares. Pero no lo son. Si el objetivo estuviera con el diafragma totalmente abierto, hubieran sido, pero en este caso lo tenía ligeramente cerrado.</p>
<p>El diafragma del objetivo al irse cerrando no es circular. En particular, en este caso, tiene cinco hojas que según se van cerrando dejan un hueco que es casi un pentágono perfecto. Un punto de luz, al pasar por el diafragma que tiene esta forma, en lugar de generar un círculo de luz sobre el sensor, genera estas figuritas tan curiosas.</p>
<p>La siguiente foto es casi la misma, pero tomada con el objetivo totalmente abierto (f1/1.8), con lo que en lugar de tener un diafragma con forma de pentágono, se tiene uno circular que es el propio objetivo. Los resultados son totalmente distintos, ¿no?.</p>

<content:encoded><![CDATA[<p>A couple of months ago I purchased a classic lens for my Nikon DSLR's called the Nikkor 50mm 1.8D or "Nifty Fifty" as the legend is known. My D40 lacks built in auto focus so you have to manually focus this lens, but for barely over 1 bill, how could I pass it up?</p>
<p>Tachikawa Bicycle Park, my favorite photo so far-<br />
<a href="http://www.flickr.com/photos/amberandclint/2427083242/" title="Tachikawa Bicycle Park by Steezus, on Flickr"><img src="http://farm4.static.flickr.com/3271/2427083242_ea365db4ec.jpg" width="500" height="333" alt="Tachikawa Bicycle Park" /></a></p>
<p>With such a large aperture it can sometimes be very difficult to get your subject in focus, I think get my focus correct in about 1 out of 5 photos when I am below f2. I need more practice!</p>
<p>Train ride leaving Kawasaki-<br />

<p>I apply tone mapping to a lot of my photos in an awesome program called <a href="http://www.hdrsoft.com/">Photomatix</a>. Photomatix can really bring out the color in a photo and does a great job of creating HDR images as well. A lot of people do not like tone mapping and HDR, but I personally love the look.</p>

<p>There's something about this photo that I like. I think its the nifty pattern the fence bokeh makes in the background. And maybe the pop of color from the flowers against the gray of the fence. I wasn't originally a bit fan of this one, but it has grown on me a bit.</p>
<p>I was all excited about having the day off, and was hoping to get out and do some shooting today, but alas it's raining. So I'll have to wait a bit to finish up that roll of film. But at least I got my oil changed, and I've been needing to do that for a while now. Guess I'll spend the rest of the afternoon watching some TV with the katzen.</p>
<p>I'm also a bit torn on my upcoming dslr purchase. I've been saving for a Nikon D80, but I've been doing some research, and I've found the the D200 I can get used for a decent price. (for the body only, vs the D80 package). Its probably way more camera than I'll ever need, BUT it will meter with my old manual Nikkor lenses.  The D80 will work with those lenses as well, but it won't meter. I'm not sure how much of a pain that will be for me, or if buying the D200 used is even a good idea. Although the site I saw it on, I have purchased from in the past, and they've been nothing short of fantastic, so I'm not terribly worried. Any comments or ideas are welcome. I need some major help with this decision.</p>

<content:encoded><![CDATA[<p>Precisiamo subito. Non esiste il fuoco <em>perfetto</em>.</p>
<p><strong>Un obiettivo obbedisce alle leggi della fisica e dell'ottica e permette di mettere a fuoco perfetto attraverso una lente su una superficie bidimensionale solo un piano altrettanto bidimensionale.</strong></p>
<p>In parole povere, su una fotocamera riusciremo a mettere a fuoco perfettamente solo la zona corrispondente a un foglio di carta piatto.</p>
<p>In breve, se mettiamo a fuoco una colonna, tutto quello che è sul piano dimensionale della <em>messa a fuoco precisa</em> risulterà a fuoco, tutte le sue altre dimensioni tridimensionali risulteranno sfocate.</p>
<p>Questo perché il piano pellicola è bidimensionale, nell'occhio umano questo non succede essendo l'occhio un elemento sferoidale.</p>
<p>Lo schema qui sotto spiega meglio quanto appena detto.</p>
<p><img class="alignnone" src="http://www.funsci.com/fun3_en/lens/lens_01.gif" alt="" width="375" height="322" /></p>
<p>In pratica la distanza di messa a fuoco su un piano bidimensionale risulta (anche se di poco) diversa anche fra il centro della foto e i suoi bordi poiché la luce percorre una distanza diversa.</p>
<p><em>Nel disegno qui sopra la luce percorre più distanza fra la punta della fiamma che dal suo centro.</em></p>
<p>In termine tecnico la "sfocatura" si chiama col nome poetico di <strong><a href="http://it.wikipedia.org/wiki/Circolo_di_confusione">Circolo di confusione</a></strong>.</p>
<p>Detto in soldoni il Circolo di confusione è il cerchio (o allargamento) che viene prodotto da un punto quando questo risulta fuori fuoco. Nei punti luminosi questo è ovviamente più evidente.</p>
<p>Il Circolo di confusione di una fotografia è visibile all'occhio umano solo quando supera una determinata dimensione. Si intende di solito 0,2mm. Questo limite può essere calcolato per <a href="http://www.dofmaster.com/digital_coc.html">ogni dimensione di sensore</a> e per ogni tipo di stampa. Ovviamente più ingrandisci una immagine, più il circolo di confusione diviene visibile.</p>
<p>Il campo di profondità della foto che risulta "a fuoco" in cui il Circolo di confusione non è visibile è quindi la <a href="http://it.wikipedia.org/wiki/Profondit%C3%A0_di_campo">Profondità di campo</a> (o <a href="http://en.wikipedia.org/wiki/Depth_of_field">Depth of field</a>).</p>
<p>Ci sono vari metodi per aumentare la profondità di campo o migliorare la messa a fuoco. E anche vari metodi per diminuirla per ottenere effetti voluti.</p>
<p>La dimensione del Circolo di confusione e la messa a fuoco dipendono fondamentalmente da questi fattori:</p>
<p><strong>- </strong><strong>Focale</strong>: un <strong>obiettivo <a href="http://it.wikipedia.org/wiki/Grandangolo">grandangolo</a></strong> (&#60;50mm) ingrandisce meno il campo di visione di un <strong><a href="http://it.wikipedia.org/wiki/Teleobiettivo">teleobiettivo</a></strong> (&#62;50mm) e quindi <strong>anche se la foto sarebbe sfocata</strong> il nostro occhio non se ne accorge. Per questo usare obiettivi con focali minori diminuisce il rischio di foto sfocate, è anche il motivo per cui molte compatte montano una ottica con un grandangolo molto spinto senza nemmeno messa a fuoco.</p>
<p><strong>- Apertura del diaframma</strong>: più un <a href="http://it.wikipedia.org/wiki/Diaframma_(ottica)">diaframma</a> è aperto e più i raggi luminosi percorrono ovviamente la via più esterna dell'obiettivo facendo più "strada" e rischiando di rendere fuori fuoco più facilmente un soggetto.<strong> Un diaframma molto chiuso quindi permette di aumentare la profondità di campo. Per chiudere un diaframma e far passare la stessa quantità di luce però dovremmo usare dei tempi di esposizione molto più lunghi rischiando di rendere la foto mossa.</strong></p>
<p><strong>- Distanza del soggetto</strong>: ovviamente più una serie di soggetti sono distanti e più rimangono a fuoco fra di loro essendo la differenza fra le dimensioni dei Circoli di confusione minore in senso assoluto ripetto a chi osserva (per fare un esempio facile, nessuno si rende conto della dimensione di una stella rispetto a un'altra anche se i loro diametri reali sono in genere molto diversi).</p>
<p><em>Alcuni approfondimenti:</em></p>
<p>Per ridurre l'effetto dell'aberrazione ai lati dello scatto alcune case produttrici di obiettivi han creato le ottiche "asferiche". Normalmente la messa a fuoco decade sui bordi e così anche la fedeltà dei colori avendo questi colori lunghezze d'onda differenti (per lo stesso motivo di cui parlavamo all'inizio, il percorso della luce è più lungo sui bordi che al centro)</p>
<p>Queste lenti vengono prodotte con tecniche costose permettendo però risultati incredibili per quanto riguarda la nitidezza. In pratica vengono tagliate lenti con superfici non sferiche che permettono di ricreare sul piano pellicola una immagine con la minore aberrazione e caduta di rendimento dell'immagine possibile.</p>
<p><img class="alignnone" src="http://www.opticscom.com/img/aspDrwg.gif" alt="" width="351" height="330" /></p>
<p>Inoltre tali ottiche hanno un numreo maggiore di lamelle di diaframma e il <a href="http://it.wikipedia.org/wiki/Bokeh">Bokeh</a> risultante è di migliore qualità.</p>
<p>- Il <strong>bokeh</strong> possiamo riassumerlo come utilizzo creativo del Circolo di confusione. Sembra una cosa minima, ma mettere insieme vari elementi di qualità rende una foto più gradevole anche a chi di fotografia o ottica non è avvezzo.</p>
<p><img class="alignnone" src="http://www.the-digital-picture.com/Images/Other/Canon-50mm-Lens-Bokeh-Comparison.jpg" alt="" width="516" height="330" /></p>
<p>Esempio di diverso bokeh fra tre obiettivi canon con numero di lamelle diverso.   <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-1.2-L-USM-Lens-Review.aspx">Canon EF 50mm f/1.2 L USM Lens</a> obiettivo asferico (sinistra), <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-1.4-USM-Lens-Review.aspx">Canon EF 50mm f/1.4 USM</a> (centro) and <a href="http://www.the-digital-picture.com/Reviews/Canon-EF-50mm-f-1.8-II-Lens-Review.aspx">Canon EF 50mm f/1.8 II</a> (destra)<br />
Fonte: <a href="http://www.the-digital-picture.com">Digitalpicture.com</a></p>
<p><strong>Lo sfocato voluto</strong>: in molti casi mettere fuori fuoco alcune parti della scena serve a metterne in risalto altre. Ridurre la profondità di campo può servire per determinati e specifici casi. Cfr. <a href="http://it.wikipedia.org/wiki/Bokeh">Bokeh</a></p>

<content:encoded><![CDATA[<p>I can't believe I hadn't tried this until now. Dad has had his 5D for a week longer than I have had the 40D now and I've had the Sigma 30mm 1.4 for nearly as long. Anyway, last night I decided to see how bad the vignetting would be from the lens on a full frame camera. So I grabbed the 5D and fired off a couple of shots.</p>
<p><a href="http://www.flickr.com/photos/-spam-/2677950531/"><img class="alignnone" src="http://farm4.static.flickr.com/3034/2677950531_5b2f5680ca.jpg?v=0" alt="" width="500" height="333" /></a></p>
<p>First thing I noticed was not the vignetting but the colours and the DOF. Could not believe just how different the images from the lens looked on the different camera. The bokeh was a million times smoother and the colours, oh how I could go on all day about the colours. But I will just say, they are awesome as far as I am concerned. Sure, there is that nasty and rather obvious vignetting but eh, it is still a usable, fast 30mm lens.</p>
<p>I also tried to see how close I could get a shot using it with the 40D and well, its almost there, but at the same time, no where near in my opinion.</p>

<description><![CDATA[Bokeh (dal giapponese &#8220;Boke&#8221; ぼ け, &#8220;sfocatura&#8221;) è un termine fotografico]]></description>
<content:encoded><![CDATA[<p style="text-align:justify;"><strong>Bokeh</strong> (dal giapponese "Boke" ぼ け, "sfocatura") è un termine fotografico da qualche anno in voga che sta <a title="A garden in summer" href="http://www.flickr.com/photos/jjjohn/1429937344/"><img class="alignright" src="http://farm2.static.flickr.com/1155/1429937344_262bc668d4_m.jpg" alt="" width="240" height="166" /></a>sostituendo la terminologia paritetica italiana "Contributo dello Sfuocato" o "Resa dello Sfuocato". Si riferisce alla tecnica che fa un utilizzo creativo della capacità di un obiettivo di mettere bene a fuoco solo una limitata porzione dei piani di cui è composta l'immagine fotografica. In queste aree sfuocate, una resa speciale la hanno le luci che, a seconda della correzione dell’aberrazione sferica dell’ottica usata, possono risultare in quello che viene definito “buon bokeh” dei punti di luce sfocati e diffusi e nel “cattivo bokeh” dei cerchi luminosi con bordi piuttosto marcati.</p>
<p style="text-align:justify;"><!--more--></p>
<p style="text-align:justify;">Il bokeh dipende essenzialmente dall'apertura del diaframma e dal numero di lamelle che compongono lo stesso. Poiché la definizione dei dettagli fuori fuoco è minore man mano che si apre il diaframma, ne consegue che lo sfocato è più morbido quando si lavora a grandi aperture, mentre i passaggi sono più netti se l'apertura diminuisce. A seconda poi del soggetto sfocato, la sua resa può darci alcune informazioni sull'obiettivo. In generale le alte luci sono più sensibili al bokeh del resto; alte luci perfettamente circolari indicano probabilmente che l'obiettivo è stato usato a tutta apertura; se sono poligonali, invece, vuol dire che il diaframma è stato chiuso di almeno un valore, e talvolta è possibile addirittura contare quante sono le lamelle del diaframma dell'obiettivo. Quindi l'apertura del diaframma ha un'influenza sul bokeh, ed il numero delle lamelle un'altra. Anche la posizione del diaframma ha la sua importanza.</p>
<p style="text-align:justify;">In generale, quindi, i migliori obiettivi (per quanto concerne il bokeh) sono quelli che hanno sia un'elevata apertura (ad esempio f/2 o f/1.4), che un elevato numero di lamelle del diaframma che, anche qualora <a title="Little stars" href="http://www.flickr.com/photos/jjjohn/1949102662/"><img class="alignleft" src="http://farm3.static.flickr.com/2233/1949102662_c1286eea01_m.jpg" alt="" width="240" height="160" /></a>l'obiettivo venisse utilizzato diaframmato, continuano a simulare un'apertura 'quasi' circolare. In alcuni casi, addirittura, le lamelle dei diaframmi hanno un andamento curvilineo che consente di 'ammorbidire' la forma del poligono creato quando il diaframma viene chiuso.</p>
<p style="text-align:justify;">Ricordiamo, comunque, che un altro importante fattore che determina la qualità del bokeh (e spesso ne costituisce l'elemento principale) è l'<em>aberrazione sferica </em>, che determina il modo in cui le alte luci fuori fuoco vengono resi in termini di intensità della luminosità. Un buon obiettivo, quindi, avrà delle alte luci 'morbide', rese in maniera meno 'netta', con una migliore sfocatura dei loro bordi ...</p>
<p style="text-align:justify;">Volete degli esempi di un ottimo bokeh? Li trovate <a href="http://fiveprime.org/hivemind/Tags/bokeh,leica">qui</a>, dove sono riprodotte delle foto effettuate da un obiettivo particolarissimo, il Leica Noctilux 50mm f/1.0 con cui, come facilmente potete osservare, anche lo sfocato diventa componente integrante della foto, elemento creativo dello scatto stesso.</p>

<br />
Today is Bokeh Wednesday!<br />
</span><br />
</p>
<p>It's not always easy finding your way.<br />
To keep true to yourself and those you love...<br />
To keep busy and work hard...<br />
And not lose direction.<br />
It's a challenge.</p>
<p>As I sat and watched the world wake up this morning,<br />
Sipping my coffee in the cool morning air,<br />
I saw this snail.<br />
Making his way.<br />
Finding his way.</p>
<p>And while he didn't make much progress<br />
From first sip to last sip of my coffee<br />
He had great determination.<br />
Kept moving forward.<br />
No matter the obstacle.</p>
<p>So today<br />
Find your way<br />
Like this snail<br />
Move forward<br />
Disregard obstacles<br />
And keep true to life, love, and all the good that this world has to offer.</p>

<content:encoded><![CDATA[<p>I spent a few days in Kagoshima City last month, specifically the tenmonkan area (天文館). Host to countless shops, bars and restaurants, tenmonkan is a nice change from Tanegashima where the streets play host to the odd stray cat and passing tumbleweed.</p>
<p style="text-align:center;"><img class="aligncenter" src="http://farm4.static.flickr.com/3264/2628373486_d1d67bee81.jpg" alt="Motorbike" /></p>

<p>I spent most of day wandering around the city's many streets and back alleys, taking photos of whatever caught my eye. On my second day  I hopped on a train to the outskirts of the city and realised that this was the first time I had been on a train in Kagoshima!  As expected, it arrived and departed on schedule to the second!</p>
<p style="text-align:center;"><img class="aligncenter" src="http://farm4.static.flickr.com/3184/2628142880_7e465014ce.jpg" alt="Train" /></p>

<p>There wasn't much to see in the countryside, I guess everything looked a bit too much like Minamitane! So I caught a train back to the city and concentrated on shots of the city dwellers.</p>
<p style="text-align:center;"><img class="aligncenter" src="http://farm4.static.flickr.com/3285/2672723409_4f353c4257.jpg" alt="" width="500" height="350" /></p>

<p style="text-align:left;">After visiting a nice reataurant and a couple of bars, I dodged the rain and shot into the early morning. Things look great in the wet - the streets sparkle and umbrellas alwyays look cool!</p>

<content:encoded><![CDATA[<p>Thanks to my <a href="http://www.flickr.com" target="_blank">Flickr </a>addiction,  I recently learned about the photographic technique called <a href="http://en.wikipedia.org/wiki/Bokeh" target="_blank">bokeh</a>.  I'm totally obsessed with it now.   I had been taking shots with bokeh before I actually knew what it was, but now I guess I'm more conscious of it.</p>
<p>The term comes from the Japanese word for<em> bokeaji,</em> which means "blurry."  It's the out-of-focus area of a photograph produced by a camera lens (not through post-processing).  Usually, there will still be a large part of the picture in focus, and the bokeh will help reduce background distractions and give the picture a more artistic feel.</p>
<p>Here are some of my bokeh shots:</p>

<p>There are several Flickr groups dedicated to bokeh -- <a href="http://flickr.com/groups/extreme_bokeh/" target="_blank">Extreme Bokeh</a>,<a href="http://flickr.com/groups/bokehwhores/" target="_blank"> Bokeh Whores</a>, <a href="http://flickr.com/groups/bokeh_/" target="_blank">Bokeh: Smooth &#38; Silky</a> and <a href="http://flickr.com/groups/okay-bokeh/" target="_blank">Bokeh Glaore</a>, just to name a few. So if you want to see more examples of bokeh, that are probably better than mine, check them out.</p>

<p>So I broke my 50mm 1.8 lens. This picture is what bokeh looks like from a lens without a front element! yay! Well i popped it back together and it still basically works, it just doesn't auto focus anymore which is fine except it makes self portraits incredibly hard.</p>
<p>Well anyways, i'm considering buying a replacement lens... i'm thinking about the 50mm 1.4 or the 85mm 1.8. However if i do that then i won't be able to get a small pocketable camera... so i'm not sure which i should get.... small camera (probably panasonic tz5) ooooor spiffy new lens. decisions, decisions! Any suggestions?</p>

(Is it timothy or meadow foxtail?) It was taken with a 100mm macro lens. The background blur of that lens is just fantastic and has opened up a new world for me. I know that I will be spending a lot more of my time crawling on my knees with a monopod in the future. <a href="http://psc.photoshelter.com/image/PSC001270466" target="_blank">This image</a> is priced at $50 (royalty-free) in my PhotoShelter Collection <a href="http://psc.photoshelter.com/ewk" target="_blank">portfolio</a>.</p>

<p>I love my Canon 50mmf1.8 lens.  It takes really sharp photos, it's a good low light lens, and bokeh is just smooth as butter!</p>

<content:encoded><![CDATA[<p>I am so impressed by this lens, I have to blog about it.</p>
<p>I've got the Nikkor 50mm f/1.4D and the Nikkor 85mm f/1.4D, both of which produce outstanding (world-class even!) colors, contrast, bokeh, and sharpness. I consider both to be must-have lenses. Those aren't the lenses I'm blogging about now, though, those are just my benchmark.</p>
<p>The killer lens is the <a title="ATX PRO DX 50-135mm f/2.8" href="http://www.tokinalens.com/products/tokina/atx535prodx-a.html" target="_blank">Tokina ATX 50-135mm f/2.8 PRO DX</a> lens. This is a DX lens, made for crop-sensor cameras. It retails about $650, which is less than half the price of the Nikkor 70-200 (a roughly equivalent effective focal length). To me, its colors, contrast, sharpness and bokeh rival my two super-fast primes, and probably the Nikkor 70-200. No, it's not f/1.4 fast, but f/2.8 is great for a zoom. Seriously, I'm blown away by this lens. Let's compare.</p>
<p>First, a couple of nice shots from the 50mm.</p>
<p><a title="swings by kevwil, on Flickr" href="http://www.flickr.com/photos/driven2code/2598088023/"><img src="http://farm4.static.flickr.com/3246/2598088023_752488d392.jpg" alt="swings" width="500" height="332" /></a></p>
<p><a title="Victoria 4 by kevwil, on Flickr" href="http://www.flickr.com/photos/driven2code/2550631668/"><img src="http://farm4.static.flickr.com/3100/2550631668_a3f10e23a0.jpg" alt="Victoria 4" width="500" height="332" /></a></p>
<p>And a nice shot from the 85mm (haven't posted many from that lens on Flickr yet).</p>
<p><a title="peregrine falcon by kevwil, on Flickr" href="http://www.flickr.com/photos/driven2code/2582315407/"><img src="http://farm4.static.flickr.com/3163/2582315407_1a68120ba8.jpg" alt="peregrine falcon" width="500" height="400" /></a></p>
<p>Now, the Tokina.</p>
<p><a title="beautiful horses by kevwil, on Flickr" href="http://www.flickr.com/photos/driven2code/2617331594/"><img src="http://farm4.static.flickr.com/3214/2617331594_c6059c0b0a.jpg" alt="beautiful horses" width="500" height="332" /></a></p>
<p>no post processing!</p>
<p><a title="harris hawk - sin city style by kevwil, on Flickr" href="http://www.flickr.com/photos/driven2code/2587269971/"><img src="http://farm4.static.flickr.com/3194/2587269971_cdbfea5e9c.jpg" alt="harris hawk - sin city style" width="500" height="254" /></a></p>
<p>using the "sin city" Lightroom preset for colors, but look at that bokeh!</p>
<p>To me, this is another must-have lens if you have a crop-sensor camera (not a Canon 5D or 1Ds ??, or Nikon D3/D700, etc.) and need a medium-range zoom for wildlife, portraits, or sports. This lens is a steal for the money, almost as much bang-for-the-buck as a 50mm! <a title="Adorama" href="http://www.adorama.com/TN50135NKAF.html" target="_blank">Go buy one!</a></p>
