Bicicletas casi a prueba de robo

Bueno, son concept-bikes nomás, pero el Juri Zaech parece sugerir “para robarte esta bicicleta al menos, vas a tener que llamarte igual”.

Si bien le faltan algunas partes fundamentales, están buenos los vocetos, o al menos, bastante curiosos… Je, bueno, un inconveniente podría ser el de tener un nombre largo, y extremidades cortas. Tal vez, en ese caso lo mejor sea fabricarlas con algún apodo :)

Veremos en un tiempo si consigue quién las fabrique de forma accesible…

Write a Bike






  • Note:
    Thanks for all the support! I appreciate it very much.
    I am currently working on a way to produce a prototype of one of the bikes.
    I'll keep you posted when things proceed. Have nice ride!

McDonald’s entra al negocio de las bodas

Leyendo gacetillas, me encontré con ésta noticia que me dejó pasmado… Definitivamente, hay algo en el mundo que está cambiando… Para mal!
A PRINCIPIOS DE ENERO DE 2011 LANZARÁ UN SERVICIO DE BANQUETE DE BODAS EN TRES DE SUS SUCURSALES DE HONG KONG
15-10-2010 | La cadena de comida rápida McDonald’s lanzará el año próximo un servicio de banquete de bodas en tres de sus sucursales de Hong Kong, una alternativa a los costosos paquetes que ofrecen establecimientos tradicionales.
La propuesta incluirá los habituales menúes de la cadena Mc Donald´s que se podrán pedir preferiblemente en caja y no incluirá bebidas alcohólicas.
Hong Kong será el primer territorio en el que la marca pone a prueba este servicio. Además del clásico lugar donde asisten comensales, las tres sucursales tendrán un espacio exclusivo para festejar bodas.
En Argentina el gasto promedio de una boda (en el estrato social medio, medio alto y alto) es de $ 50.000. El ritual que en el país se celebra 90.000 veces al año, es un mercado que mueve $800 millones.

Como obtener el mejor color en tus fotos

Excelente artículo de Lifehacker que detalla y resume desde tanto teoría de los colores, pasando por los puntos a tener en cuenta a la hora de fotografiar, y finalizando por los aspectos básicos en post-producción.

How to Get the Best Color Out of Your Photos

How to Get the Best Color Out of Your PhotosBlack and white has long been the default "artistic" style for photographs, so it can be easy to forget how compelling a color photograph can be. Here's an in-depth guide to help you get amazing color in your photos.

An Introduction to Color

How to Get the Best Color Out of Your PhotosWe could talk for hours about the science of color and how it works, but that's only going to go so far in helping you with your photos, so we'll save it for another time. Instead, let's just have a quick chat about the color wheel and what we can do with it.

Types of Color

Before we can get into using color, we have to have a basic understanding of the types. So let's breeze through this so we can get to the fun stuff.

How to Get the Best Color Out of Your PhotosPrimary colors are colors at their most basic level. We mix primary colors together to make the other colors. Here we have red, yellow, and blue. On the computer we're actually dealing with red, green, and blue (RGB) as our primaries, but that's not really relevant for what we want to do here: create nice color harmonies.

How to Get the Best Color Out of Your PhotosWow, those secondary colors look ugly together. In most cases, most color groupings don't look fantastic when shown together. They tend to look better with colors outside of their group. But what are secondary colors? When you mate two of the primary colors, you end up with a secondary. For example, yellow and blue makes green—but you probably already knew that.

How to Get the Best Color Out of Your PhotosTertiary colors are the third generation—the grandchildren of the primary colors...except that's a bad analogy because you make tertiary colors by combining a primary and a secondary color—and that kind of breeding is frowned on almost anywhere you go.

How to Get the Best Color Out of Your PhotosThese are colors that complement each other. (Did you figure that out already?) If you're looking at the color wheel, they're the colors directly across from one another. They're supposed to look nice together but that's not always the case.

How to Get the Best Color Out of Your Photos
Analogous colors are the colors located in close proximity on the color wheel. In a simplified color wheel like the one shown above, they're directly next to each other. On a color wheel with more colors than your eye can count, they don't need to be strict neighbors—just pretty close. Using an analogous color (or two) instead of a direct complement can sometimes make for a better color harmony:

How to Get the Best Color Out of Your Photos

At least I think so, anyway. Color can be a very personal thing, so you want to choose harmonies you enjoy. Even if you don't think you have a preference, you probably do. Color is one of the first things we connect with when we're young. Think about how many times you were asked, "What's your favorite color, Sammy?" If your name was Sammy, you probably heard that question a lot.

So if color is such a personal thing, how do we make appealing color harmonies? Well, there are really only so many basic colors to work with and there are some general principles (some of which we've now covered) that can help to guide you. Let's look at some examples and pick them apart.

How to Get the Best Color Out of Your PhotosWhy do red and cyan work well together? Red is our primary color in this bunch and cyan is a tertiary color. Cyan is also a split complement of red. You get a split complement when you take a color, find it's complement, and then choose one of the complement's analogous colors. In this case red's complement is green. Cyan is analogous to green and therefore is a split complement. Of course, what you're looking at here isn't exactly red or exactly cyan, plus there are tonal shifts, but the concept is still the same.

How to Get the Best Color Out of Your PhotosGood old blue and green, the colors of my high school. The problem is that my high school used really obnoxious combinations of the two. In fact, while this looks alright, it's not necessarily the most compelling. The problem is that the colors are really close together on the wheel. They're practically analogous. While they look alright together, and could be very compelling in some cases, there's not a lot of variation going on here. Let's see what else we can do...

How to Get the Best Color Out of Your PhotosThis is interesting. Here we have the blue and green with orange and red. Orange and red are also very close together on the color wheel, having the same sort of relationship as blue and green. While they might not always be compelling combinations alone, they're pretty nice when the four are combined. If you're looking at the color wheel, you may have noticed these four colors form a rectangle. When looking for a starting point for basic color harmonies, drawing shapes on the color wheel can help.


How to Get the Best Color Out of Your PhotosLastly, let's take a look at something that's probably pretty familiar. These are the colors of Flickr, and they were derived from a triad. A triad is an equilateral triangle drawn on the color wheel. If you're playing along, you'll notice if you connect magenta and cyan, the missing link in the triangle is yellow-orange:

How to Get the Best Color Out of Your PhotosThe Flickr colors are based in this triad, but orange was dropped for a simpler harmony. If you only want two dominant colors, try playing around with triads and removing one color for some interesting options.  

   
How to Get the Best Color Out of Your PhotosBefore we move on, we have to talk about Adobe Kuler. If you're looking for a way to find new color harmonies, Kuler is a great (free) web-based tool to help you look at color in different ways.

That said, how does all of this apply to photography? 

Color Theory in Photography

How to Get the Best Color Out of Your Photos
Now we're knee deep in the water and so I have to ask: Have you ever taken a picture of a body of water during a sunset? I have. You're probably looking at it right now, since it's right above this sentence. It's not going to win any awards for Best Sunset Photo or even make it onto the cover of a trashy novel, but it does illustrate a point about color: Color harmonies can show up naturally in the most regular of places. The orange of the sun and the blue of the sky complement each other. If you don't happen to have a lake and a sky handy, dress up one of your caucasian (or mostly caucasian) friends in blue jeans and a white t-shirt. That's a popular combination because white people are really more orange than white—especially if they're jaundiced. If you have a jaundiced friend, or at least one with a spray tan, go buy a pair of jeans and you're set for life.

How to Get the Best Color Out of Your Photos
Do you think this spray tanning room has blue walls by accident? Neither do I.

Spray tanning isn't the only industry taking advantage of color harmonies. America's plastered with an idea we've already discussed:

How to Get the Best Color Out of Your Photos
Before Flickr there was the US of A. This is the same dropping-a-color-from-a-triad concept, only less saturated. Flickr's color scheme is secretly patriotic. Who knew?

But what does this all mean? It means there are color harmonies everywhere you go, and you need to look for them. Capturing a photo with good color can be as simple as aiming the lens in the right direction, framing up, and pressing the shutter. But this is the digital age, so let's look at how we can manipulate reality for better photos when reality just doesn't live up to the task.

 

Before the Shutter

How to Get the Best Color Out of Your Photos
Don't get too excited. Most of what you can do to manipulate color for the good of your photobefore pressing the shutter is thinking and planning. Sorry, there's not a lot of magic here.

Subjects and Backgrounds

How to Get the Best Color Out of Your PhotosThis is easier than you think. Just like the spray-tanner against the blue wall, it can be as simple as placing your subject in front of the color you want. In the photo above, I placed my friend Christine in front of a white wall that gained a green tint from some glass that's out of frame. Christine's skin is yellow-orange and her lips are pink. Basically, Christine forms a split complement of green.

How to Get the Best Color Out of Your Photos
Remember the rectangle example from earlier? Here it is in practice. We have analogous warm shades on the ground (orange and red) and analogous cool shades behind the trees (green and blue).

 

  How to Get the Best Color Out of Your Photos
Here's another example of split complements at work. See the tiny piece of yellow on that foam football? The purple and cyan are its split complements.

 

 

 

 

How to Get the Best Color Out of Your PhotosObvious complements aren't the only solution, however. You can create some beautiful color harmonies simply by sticking with analogous colors and shifts in tone. This is one of those situations where green and blue—two very similar colors—can work subtly together to create a nice effect.

The takeaway here is pretty simple: Put your subject in front of a background that will create a color harmony, or change your subject to suit the background you have. It doesn't matter if your subject is a human female or a foam football, the principles stay the same.

Light

How to Get the Best Color Out of Your PhotosColor doesn't always look the same and that's because of light. Light can often be a huge nuisance, whether you have plenty of it or not enough. We're not going to get into lighting here, but we do need to touch upon its effects on color. As you can see in the example above, the color of the subjects benefits from some extra red light. You can see it the most on their skin. This is just a casual snapshot, but the color pops because of the light. This light came from the same sun as less richly colorful photos taken earlier in the day, but because the sun had begun to set at the time the photo was taken, the lighting was more direct (instead of overhead). Around sunrise and sunset are the two times during the day when you get the best outdoor light and, by extension, the best natural outdoor color. Both of these periods are referred to as the golden hours. Make use of them when you can. Use a calculator if you need to.

How to Get the Best Color Out of Your Photos

Chances are you're not scheduling your family vacation photos around the golden hours of the day, so how can you take advantage of the light you have? In terms of color, you want to be aware of the temperature. You may have noticed a little chart to our left. This gives you the idea of the light temperature (and therefore color cast) you can expect at certain times of the day. Pretty handy. When you're indoors, artificial light changes as well. Tungsten lighting will get you that nice yellow-orange glow you can get from the sun. Fluorescent lights—everybody's (least) favorite—produce a fairly dull white light with a little extra green. Whatever your lighting situation may be, know what it is. It will have an effect on the color in your photo.

Tricks in Post

You can't fix everything by post processing your photos—not easily, anyhow—but there are a lot of neat things you can do. Now that you know how to use color, let's look at abusing it.

There are a lot of clever Photoshop tutorials out there dealing with color and just about everything else you might want to do to your photos. Generally they deal with using the tools exactly as they were intended and involve quite a bit of work. This section isn't about best practices, but about getting the job done quickly and still doing it well. These tricks are about getting some neat color effects, from subtle to extreme, without too many steps or anything all that complicated. Although Donnie is much more entertaining, here's a little information on some of the adjustments we'll be looking at so you know what you're getting into.

Not too bad, right?

Unbalanced Color with the Curves Midpoint Gray Eyedropper

Most of the time you probably want to white balance your photos, but sometimes unbalanced color works in your favor. Sometimes added warmth or a lack of saturation can give a picture the effect you're looking for, so let's take a look at using the midpoint gray eyedropper in Curves to get some unbalanced color effects.

How to Get the Best Color Out of Your PhotosWhat the midpoint gray eyedropper does is sample a color in the photo and then change the color balance of the entire photo to neutralize it so it will be a neutral, middle-of-the-road (or, well, tonal scale) gray. If you were to use it to select something blue, for example, the sampling would cause curves to neutralize it using that color's complement. Most blues will get you an orange-ish complement and so you'll see your photo warm up. If you select a warmer color, it'll cool down your photos. This is a really fast way to change the feel of your photo with color complements.

How to Get the Best Color Out of Your Photos

Warming up or cooling off your photos—or adding any color, really—can be done pretty quickly and easily using a faux-Photo Filter adjustment instead. So why use Curves? Curves gives you more control and you can tweak the settings after you've discovered them with the sampler. You can also make your own adjustments to the contrast after playing with the color, letting you do all of your work in one place. If you're not sure how to adjust individual color channels with Curves, check out the next section for a trick for getting extreme color effects using—you guessed it—individual color channels.

Split Color Dominance for Extreme Color with Curves

How to Get the Best Color Out of Your PhotosCurves is a very powerful tool, and it's easy to abuse that power—so let's do it! You can create some really interesting color effects by splitting which channels are dominant in your photos.

This is really easy to do, but daunting if you haven't tried it before. To get started, either hit Command/Control + M to bring up Curves or go to the Layer menu, choose New Adjustment Layer, and then select Curves. From there you'll see something along the lines of what's in the picture to the left. In that picture, I have the blue channel selected. Chances are you have the RGB layer selected, since that's the default. (Note: if you're not using RGB you may have different channel names.) From the channel menu, select Red. We'll start there and work our way down.

 
Adjusting Light and Color with Gradient Overlays

How to Get the Best Color Out of Your PhotosSubtlety is not the strong suit of either of those tricks. If you want to show a little more restraint but still adjust color in an interesting way, gradient overlays might be your cup of tea.

The idea is pretty simple:

  1. Create a new layer on top of your photo.
  2. Use the Gradient tool (it swaps with the Paint Can in the toolbar) to create a gradient to fill the layer.
  3. Set the blending mode of your gradient layer to Overlay.
  4. Adjust the opacity of that layer to get the desired effect (less is generally more in this case).

In the example video above you can see how using a radial gradient can create a subtle, cooling spotlight to make the photo's subject pop out with the right color.

Adjusting Light and Color with Color Channel Overlays

This is one of the easiest tricks to do and generally one of the most compelling. All you do is take a single color channel from your photo, paste it in a new layer above the full color photo, and set the blending mode of that layer to Overlay. This gives you a nice, washed out and contrasty color look. Here's how you do it, step-by-step:

  1. Open up your photo and switch to the Channels panel in Photoshop. RGB should be selected, but choose Green.
  2. Select All (Command/Control + A) and then copy (Command/Control + C).
  3. Switch back to RGB and then paste (Command/Control + V) the green layer on top of your photo. This should make everything appear to be in black and white.
  4. Set the blending mode of the green layer you just pasted to Overlay and adjust the opacity to your liking (but 20-30% usually works pretty well).

Fantásticos videos HDR en blanco y negro

Vale la pena darse una vuelta por el Flickr del autor, para disfrutar de estas maravillosas creaciones, resultado de tomar cientos de imágenes con una simple cámara de fotos, post procesar cada una con Photomatix, y unirlas consecutivamente, para crear la ilusión de movimiento… Que laburitos!!!!! :)
Igualmente, les recomiendo miren todos los albums, son muy buenos!

I am always inspired (and humbled) as a photographer as I cull through the Photography Bay Flickr Group each week. As I was checking out some of the additions to the group this week, something stood out a little more than usual.
That something was Flickr user andyathlon’s additions to the Photography Bay Group Pool, which included the HDR time lapse videos below.
To capture each of these videos, Andy used a Sony A700 and captured several hundred images that he batch processed in Photomatix for the HDR effect.  You can see his full workflow description below.
Here’s Andy’s description of his shooting and post-production for these cool time lapse HDR videos:
“The main aim of my stop animations was to capture movement in a shot that cannot be seen.
I shoot with a Sony a700 and a Sigma 10-20 to capture the most out of a scene. I combine this with a B&W ND10 which allows me to create a long exposure during the day.
I start by first taking a shot to compose the scene and balance the exposure I have found that this can vary heavily under the light conditions.
I aim to keep the exposure at around 1.5-3 seconds, this allows me to capture movement of people but not the detail. I do this using a Hahnel Giga T pro wireless remote. With this remote I can set exposures, delays and intervals.
Once I have the shot set up and balanced the exposure, I set the camera in Jpeg so I can store thousands of shots instead of hundreds then set my remote firing and wait……. and wait…….
Typically I am to get at least 700 shots, this will allow me to create a 70 second video if I use 10 frames per second in quicktime. Some of my longer videos have over 3-4 thousand shots which resulted in massive file sizes and huge processing times.
Once I have the shots it’s time to process. I use Photomatix batch processing to combine 2 shots to create the HDR, in theory this shouldn’t work as they are the same exposure and offer no difference. I alter the HDR settings and run a test shot through to see what it looks like, changing settings to alter the strength and colour of the HDR. Once I’m happy I let it run with my pc it can take up to 30mins but can vary massively depending on size and number of shots.
Finally once all the shots are processed I import them into quicktime using open image sequence, and then export the video with HD quality settings.”
A big thanks to Andy for sharing this process with us, and being a part of the Photography Bay community.  You can head on over to his Flickr Photostream to check out more of his work.

No a la censura: Los videojuegos son arte.

La verdad que viendo el desarrollo no solo de los cinematográficos guiones de los títulos de los últimos años, sino su destacado y cuidado aspecto gráfico y sonoro, yo no puedo estar más de acuerdo. Personalmente, lo que me impulsa a jugar ciertos títulos, son 2 puntos principales: El disfrutar de todo ese despliege artístico, y sentir lo que verdaderamente una PC puede procesar en el momento, adaptando todo eso, a las decisiones del jugador.
A ésto, claramente le podemos sumar en algunos casos, posturas sociales, políticas o religiosas que no hacen más que hacer pensar al participante desde su rol de protagonista, bueno, como en toda expresión artística, es la idea, movilizar los sentidos, generar comodidad o incomodidad, brindar placer y satisfacción o controversia, pero nunca la idea es pasar desapercibido. Ni más ni menos: EXPRESIÓN.
De todas formas y trascendiendo el tema central de la nota, creo que la censura nunca es la solución.

19 de octubre: porque "los videojuegos son arte"

Los creadores de videojuegos se manifestarán el próximo martes contra una ley californiana que pretende censurar videojuegos
EUROPA PRESS MADRID 15/10/2010 12:14 Actualizado: 15/10/2010 12:30

Dibujo que recrea una escena del videojuego 'Epic Mickey'.
Los creadores de videojuegos quieren que sus obras sean consideradas arte y que no sean sometidas a restricciones o censura. La Video Game Voters Network ha distribuido una nueva misivia de un peso pesado de la industria que critica la ley que quiere sacar adelante California con respecto a los videojuegos. El objetivo de este colectivo es que la mayor cantidad posible de aficionados y profesionales del sector se unan a un día de acción común el próximo 19 de octubrecontra esta legislación.
Tras Stan Lee, Warren Spector -ahora en boca de todos por Epic Mickey- ha escrito una cartapara evitar que el Tribunal Supremo estadounidense autorice la ley de California que prohibiría la venta de algunos videojuegos a menores, entre otras restricciones. "Los videojuegos son arte, una forma de expresión artística, en la actualidad, protegida por la Primera Enmienda", ha defendido el creador de Deus Ex en una misivia distribuida por la VGVN, que en verano anunció una campaña contra la nueva legislación del estado de California.
"Eso no ha impedido que los estados traten de restringir los derechos de los artistas de nuestro medio, narradores y técnicos innovadores", ha criticado Spector. En este sentido, ha recordado que el 2 de noviembre, el Tribunal Supremo escuchará "los argumentos sobre la constitucionalidad de una ley de California que limitará la venta de videojuegos". "Este es un caso de gran importancia para ti y para mí", ha opinado el creador refiriéndose a los jugadores, y, de hecho para "todas las personas que desarrollan juegos juegos y creen en la Primera Enmienda".
El gran problema de que la ley salga adelante no es la restricción de la venta de juegos violentos a menores sino que "llevaría la censura futuro de los juegos, de manera irrevocable" y "validaría la absurda creencia de que los videojuegos están de alguna manera por debajo de la expresión creativa". "Tenemos que actuar ahora", ha dicho Spector antes de animar a los afectados a que se unan el próximo 19 de octubre a la iniciativa de la Video Games Voters Network, "un grupo de defensa de la lucha por la protección de la Primera Enmienda".
"Mucha gente, incluyendo algunos de mis héroes personales, como Stan Lee, que ya nos animó a implicarnos", ha rememorado Spector. "Ahora es el momento para que los jugadores se unany corran la voz a través de nuestras redes sociales. Ahora es el momento de pedir a cada jugador que se ponga de pie con nosotros y proteja nuestros derechos de la Primera Enmienda".

Nvidia responde inmediatamente… Con un rumor…

Evidentemente, una declaración se fabrica más rápidamente que un producto… Con ustedes, el manotazo de ahogado de Nvidia, hablando de un futuro modelo, sin especificar demasiado y sin jugarse con fechas… A mi me transmite un pedido de tiempo al mercado…

NVIDIA to Counter Radeon HD 6970 ''Cayman'' with GeForce GTX 580

AMD is undertaking its product development cycle at a breakneck pace, NVIDIA trailed it in the DirectX 11 and performance leadership race by months. This November, AMD will release the "Cayman" GPU, its newest high end GPU, the expectations are that it will outperform the NVIDIA GF100, that is a serious cause for concern, for the green team. It's back to its old tactics of talking about GPUs that haven't even taken shape, to try and water down AMD's launch. Enter, the GF110, NVIDIA's new high-end GPU under design, on which is based the GeForce GTX 580.
The new GPU is speculated to have 512 CUDA cores, 128 TMUs, and a 512-bit wide GDDR5 memory interface holding 2 GB of memory, with a TDP of close to that of the GeForce GTX 480. In the immediate future, there are prospects of a more realistic-sounding GF100b, which is basically GF100 with all its 512 CUDA cores enabled, while retaining its 384-bit GDDR5 memory interface, 64 TMUs, and slightly higher TDP than that of the GTX 480.
