Seasonic presenta una fuente para PC totalmente silenciosa

Con los avances en miniaturización y optimización de consumo de componentes, están volviendo a asomar los productos “fanless”, es decir, sin ventilador. Cosa más que bienvenida para todos los que trabajamos con la computadora al lado nuestro, por reducir al mínimo el nivel de ruido de ésta, sin depender de reguladores de velocidad, (quitando cables del interior y haciendo esto también de ayuda a la optimización del flujo interno de aire), y además, reduciendo la posibilidad de entrada de polvillo desde el exterior, cosa muy dañina para los equipos, si no se hace un adecuado mantenimiento.

Como fan de las Silent PC, (si no me creen, les dejo mi Nous Machine a modo de muestra), espero ansioso que otros fabricantes sigan éste modelo, y traigan productos así por nuestras sudamericanas tierras.

Cuando ser camarógrafo es un trabajo de riesgo…

Me encontré con esta noticia y no dudé un minuto en traerla, recordando lo que había pasado con el incidente de Tiger Woods con el fotógrafo, hace poco.

Esto es un camarógrafo que sigue cumpliendo con su deber, pase lo que pase! (Aunque es poco común de ver, estas cámaras son protegidas por un lente especial, a éste efecto, por las dudas…)

TV Cameraman Keeps Filming After A Baseball Bat Smacks His Gear

We've seen what happened when a golf ball gently bounced off a camera lens, but what happens when a baseball bat is violently flung toward a very expensive camera? And more importantly: What happens to the guy holding the gear?

Turns out that very little happens to both camera and cameraman. Or at least very little happened during Game 4 of the American League Championship Series when Brett Gardner's bat flew toward the broadcast video camera held by freelance videographer Steve Angel.

The calm videographer didn't even flinch as the top of Gardner's bat made contact with the front of his camera. Instead he focused on doing his job:

A-Rod was about to cross home plate, so that's what I was doing. I was shooting him. And then all of a sudden, if you look at the video, it gets pretty frosty.

Part of the reason Angel was even able to continue shooting as calmly as he did is that the actual camera was damage-free thanks to some protective measures:

Angel said it would cost "more than a house" to replace one of those TBS lenses if it is broken. But in front of each lens, the camera sports a protective glass cover on the outside, which was all Gardner's bat wound up damaging.

While everyone is cheering about the fact that the bat hit this protective glass cover instead of the camera lens, I'm just plain relieved that it didn't hit Angel's head. Kudos to him for staying so calm while only a few inches from a concussion. [MLB]

Paso a paso: Fotografías UV a bajo costo

Instructables es otra de esas páginas interesantes para consultar en los momentos de ocio. Quizá sea un poco facilista, o bien, los proyectos no sean tan baratos de realizar por estas latitudes, pero no cabe duda, que es una muy buena fuente de ideas para desarrollar, aunque sea, al modo de cada uno :)

Hoy, y especialmente para los fotógrafos que quieran experimentar con analógica, o bien, con métodos ópticos poco ortodoxos: Como realizar fotografías dentro del espectro Ultravioleta “a la antigua”.

Photography in the Ultraviolet spectrum or "See the World Through the Eyes of a Bee".

 

For years I've wanted to mess around with UV photography. Unfortunately, all the websites on DIY UV seem to assume an infinite amount of money and access to specialized equipment on my part. There are two things that I don't like, when someone tells me I HAVE to spend a lot of money (quartz lenses starting at $3000) or that i need specialized equipment (Wratten 18A filters, not cheap either).

So I set out to do it my way, and here's my $5 solution to UV wavelength photography.

step 1 - Finding a filter

I was wracking my brains trying to find a UV bandpass filter, when, quite literally, a light bulb went off in my head. A blacklight bulb that is. Blacklight bulbs are formed from wood's glass. Wood's glass is a uv & ir bandpass filter.
There are two kinds of blacklight bulb (at least), incandescent and fluorescent. I tested both, good for you, because the fluorescent kind DID NOT WORK. This is good because the incandescent is safer to work with, and cheaper.

step 2 - Take your light bulb

and break it, once you've broken it, take a piece that will cover your camera lens and work out a mount. I used the same mounting technique from my previous instructable. Okay, I cheated and used a glass cutter.
Here it is already to mount on my digital camera.

 

step 3 - Go outside and take some pictures

You'll need bright sunshine, and maybe a tripod, you can use flash, it puts out plenty of UV and gives you a different look.
