E&#8217; interessante, in particolar modo, la funzionalit\u00e0 che offrono la maggior parte dei cellulari di ultima generazione (Android, iPhone, WinPhone ..), che permette di salvare immediatamente le foto in un proprio spazio Cloud, spesso sincronizzato con una cartella del proprio PC di casa, cos\u00ec da non doverle trasferire nemmeno attraverso cavo o wifi, ma avendole gi\u00e0 pronte da visionare, stampare o archiviare nel momento in cui ci si siede di fronte alla propria scrivania di casa o del lavoro.<\/span><\/p>\n<div style=\"text-align: justify;\">Tuttavia, se parliamo di <u>fotografia di qualit\u00e0<\/u>, di fotografia &#8220;tecnica&#8221; o artistica, le cose cambiano.&nbsp;<\/div>\n<div style=\"text-align: justify;\">Poi \u00e8 vero che l&#8217;elemento principale che in una fotografia fa la differenza, non \u00e8 l&#8217;attrezzatura che viene usata, ma <b><u>\u00e8 il fotografo<\/u><\/b>, ovvero la bravura, l&#8217;esperienza e il tocco creativo ed artistico di colui che sta dietro l&#8217;obbiettivo.

Mi \u00e8 stato gentilmente concesso in prestito da un amico e collega), un&#8217;ottica fissa molto &#8220;luminosa&#8221; (apertura del diaframma f\/1.4 \u00e8 eccellente, e permette di ridurre notevolmente la profondit\u00e0 di campo, cos\u00ec da isolare nettamente il soggetto principale dal resto della scena sullo sfondo, che apparir\u00e0 sfuocata, anche se sarebbe meglio dire &#8220;fuori campo&#8221;).<br \/>Il secondo \u00e8 l&#8217;obbiettivo base che viene dato quando si acquista il kit con la fotocamera. Generalmente questi sono obbiettivi economici, di qualit\u00e0 medio-bassa. Tant&#8217;\u00e8 che tra fotoamatori, chiamiamo umoristicamente &#8220;<i>plasticotti<\/i>&#8221; tutti gli obbietti che appartengono a questa categoria qualitativa.<br \/>Ciononostante, vedremo dall&#8217;esame delle prove fatte, che comunque anche con quest&#8217;ultimo obbiettivo sono stati raggiunti risultati molto soddisfacenti (talvolta anche con stupore del sottoscritto), o comunque risultati eguagliabili tutt&#8217;al pi\u00f9 con una fotocamera compatta di qualit\u00e0 dotata di un discreto zoom ottico, ma non certo con fotocamere di Smartphone a focale fissa e fotosensori al di sotto di certe dimensioni.<\/p>\n<p>&nbsp; &nbsp; &nbsp;In tutte le foto scattate per il test, ho lavorato in <u><b>priorit\u00e0 di diaframmi<\/b><\/u> (<i>Aperture-priority<\/i>), in modo da avere principalmente il controllo sull&#8217;apertura del diaframma, influenzando di conseguenza la luminosit\u00e0 in entrata e la Profondit\u00e0 di Campo (d&#8217;ora in avanti, abbreviata per semplicit\u00e0 in <b>PdC<\/b>), e con una <u><b>sensibilit\u00e0 fissa a 100 ISO<\/b><\/u>, e lasciando impostare automaticamente alla macchina il valore restante (<b>tempo di scatto<\/b>) in base alla lettura esposimetrica della scena (con <i><u>misurazione valutativa pesata al centro<\/u><\/i>).<br \/>&nbsp; &nbsp; &nbsp;Le prime due foto che presento in questo blog, sono state realizzate facendo uso del primo dei due obbiettivi usati in questi test, il 50mm fisso f\/1.4. La sua straordinaria massima apertura (F\/1.4), mi consente di ridurre la profondit\u00e0 di campo al minimo indispensabile, isolando in modo evidente il soggetto dal resto della scena. Occorre notare, che non ho mai impostato il diaframma alla sua massima apertura (ma entrambe a f\/2.8), poich\u00e9 essendo abbastanza vicino al soggetto, avrei rischiato di ridurre eccessivamente la PdC, provocando cos\u00ec diversi livelli di sfocatura persino sul soggetto principale stesso (ad esempio, naso &#8220;in campo&#8221; e orecchio &#8220;fuori campo&#8221;).<\/p>\n<p>Come si pu\u00f2 notare dalla seguente foto, vista in dimensione schermo, lo sfondo appare s\u00ec sfocato, ma non eccessivamente. Guardando l&#8217;immagine nel dettaglio a risoluzione piena, invece, si nota il viso e la mano del bambino (mio figlio Alessandro ^_^) perfettamente a fuoco, ma lo sfondo &#8220;ordinatamente&#8221; sfuocato, tale da attribuire una sensazione di tridimensionalit\u00e0 tra il soggetto a fuoco e lo sfondo. Addirittura la parte sfuocata\/fuori campo \u00e8 cos\u00ec omogenea da distinguere i cerchietti tipicamente creati dalle ottiche con diaframmi ad apertura circolare, che sono ben evidenti nelle aree &#8220;fuori campo&#8221; dell&#8217;immagine.<br \/>In qualche dettaglio dell&#8217;immagine, ho anche evidenziato il punto con un cerchietto, indicandolo con il nome di <b><a href=\"http:\/\/gabrielezappi.net\/?p=10\" target=\"_blank\">Bokeh<\/a><\/b>.<br \/>(<b><i><a href=\"http:\/\/gabrielezappi.net\/?p=10\" target=\"_blank\">Bokeh<\/a><\/i><\/b> \u00e8 un termine giapponese che significa pi\u00f9 o meno, campo di confusione, o semplicemente confusione, indicando con questo termine appunto l&#8217;area dell&#8217;immagine fotografata che \u00e8 al di fuori del piano focale, o in altre parole, &#8220;al di l\u00e0&#8221;
