García Rodero nos presenta la imagen de la “España oculta”

Con un gran valor documental y artístico, se presenta en Cartagena, municipio español de la región de Murcia, una exposición fotográfica de setenta y cinco imágenes tomadas entre los años 1975 y 1988, donde se enfocan las fiestas tradicionales y la vida en general de los pueblos de la época.
La exposición, bajo el nombre de la España Oculta, es obra de Cristina García Rodero. Sus fotografías podrán verse en el Museo Regional de Arte Moderno de Cartagena (MURAM). Estas permanecerán hasta el 18 de marzo de 2012, teniendo lugar muchas de las instantáneas en los pueblos de la región murciana. Las fotografías, que son propiedad de la Agencia Magnum, poseen un alto valor. Tanto por su calidad como por su importancia histórica. Cristina García Rodero, con su obra, se inunda en aquella España profunda de finales del siglo XX que poco a poco daba paso al actual comportamiento social de los pueblos españoles. En la colección de fotos se muestra una mezcla de tradiciones religiosas y folclóricas.

The leaked release Monday night of two remixes that pair the self-proclaimed good girl gone bad Rihanna with her admitted abuser, Chris Brown, present an intense moral quandary for anyone who believes that pop music has real cultural impact. Never in my memory has the particular feeling surrounding these new songs — "dread" is a word often employed in the past week — been so pronounced. This is music many people wish did not exist.

Rihanna's X-rated "Birthday Cake" and Brown's more radio-friendly "Turn Up the Music" hit our ears like little bombs, exploding with context. They are provocations, demanding response. Even listening feels like a weighted choice, and, for most of us, the experience will be defined by the stance we'd chosen before we heard a note.

Opt out, most commentators have urged. "It doesn't matter that it's a great pop song," wrote Lucy Jones of "Birthday Cake" in the London Telegraph, adding, "Unless you're an imbecile — it'll be hard to wave your hands in the air in the clubs to 'Birthday Cake.'" "I'm headed to the bathroom to vomit," concluded Amelia McDonnell-Parry in The Frisky. Maura Johnston at the Village Voice dismissed the tracks as mediocre and deftly analyzed the viral impact of the songs, implicating all of us who've bit at this volatile catnip. "At least one of these remixes will be a massive radio track, and every blog post decrying the pairing will be part of the reason why," she wrote.

The vast majority of journalists who've weighed in are on the side of these writers, denouncing this musical reunion as a huge disappointment, an aberration, a pathetic nightmare, a tragic sign of Rihanna's further degradation, a cynical attempt to cash in on scandal — name your poison. On the other side are the fans who support the artists' own assertions that they are ready to move on.

The Record

Rihanna And Chris Brown: The Saga Continues

As I hear it, however, "Birthday Cake" is not about moving on, and that's what makes it worth a listen — at least one painful listen — to better understand the confounding stance of a young woman who's become an emblem of victimization for some, and of rebellious self-determination for others.

Here's the history that led up to this moment. Chris Brown assaulted his then-girlfriend Robyn "Rihanna" Fenty on February 8, 2009. The muscular singer and dancer repeatedly beat her as she was trapped inside his moving car. He threatened to kill her. He bit her; he choked her. He only stopped when she screamed loud enough to wake observers.

Plenty of people washed their hands of this story after hearing details of the initial incident, and I think that's totally acceptable. I'm all for the general public ignoring "Birthday Cake" and Brown's much less interesting remix. Walk away from this relationship. Don't buy these songs. Turn off the television or radio when Rihanna and Chris Brown appear. Better yet, write your radio station and tell them not to play either of these remixes. Tell your daughters and sons that Brown is a brute and Rihanna is terribly misguided. If they push you, show them the [Eds. note: This link will send you to seriously disturbing images.] sickening pictures of her bloodied face.

I'm choosing to do something else, though — to wrestle with the material at hand. As a music critic and, on a personal level, as someone who's long considered pop to be a crucial avenue for understanding the intricacies of the human heart and soul, I'm committed to engaging with the music that makes us sit up and take notice. I'm willing to try, even if those songs expose or even encourage aspects of behaviors that aren't so savory. I don't think "Turn Up the Music" tells us much; "Birthday Cake" is a different matter. So I'll continue trying to grasp what's happening in a song that makes many — but not all — of us want to turn away.

The truth is, "Birthday Cake" is not a surprise coming from Rihanna. For better or worse, she's never really embraced the role model role so many people want her to assume. After the assault, she did eventually separate from Brown — not because she wanted to, but because she worried that her staying with him would encourage her fans to accept similar dangerous situations. She told Diane Sawyer on 20/20 that she'd reversed her "selfish decision" to stay with Brown because she feared it "could result in some young girl getting killed."

Brown, meanwhile, pled guilty to his crime and was sentenced to probation and community service. With help from his many music-industry friends, he continued his career. He's currently on the cusp of a comeback that included a recent Grammy performance and win. Throughout this period, he has expressed remorse, but also behaved in frighteningly belligerent ways toward those who question his good intentions. He's made some catchy music that doesn't show much self-awareness or depth of artistic character.

Rihanna, on the other hand, has not only gone on to become one of the world's most commercially successful entertainers, she also has embraced controversy by openly exploring her ambivalent feelings about Brown, and about sexuality in general. "Birthday Cake" isn't what disqualifies her from "role model" status. She's been something else for a long time, as her music has grown more sexually explicit, transgressive and politically incorrect.

The songs Rihanna has chosen to record, and has sometimes co-written, are not ones I play for my own daughter (though yes, she's heard them on the radio, and we've talked about them). They're rarely, if ever, feel-good anthems encouraging self-empowerment. Rihanna has basically abandoned such efforts, ceding that ground to her friends Katy Perry and Beyonce. Instead, she's entered into a space previously occupied by many blues women, country singers and girl groups, where women attempt to uncover the truth behind emotional violence, without necessarily comprehending ways to escape it.

Rated R, the album that most closely followed Rihanna's assault, was a heavy effort exposing the costs of sexual abuse, but also acknowledging the allure of the abuser. (Its first single is called "Russian Roulette.") After that came two more albums, full of songs that grew ever more pornographic, from "Rude Boy," with its taunt of, "Can you get it up?" to "Only Girl (In the World)," with its plea for a lover to "take me like a thief in the night."

Rihanna's biggest hits have directly confronted the theme of sexual violence. At times, she has presented herself as a victim's champion. "Man Down" is a revenge fantasy in which she does in a rapist. "We Found Love," her ebullient dance floor anthem, turns on the moment she walks out on her bad boy: "I had to let it go," she whispers as the beat whisks her away.

Often, though, Rihanna's stance has been far more conflicted. "Love The Way You Lie," her collaboration with the equally violence-obsessed Eminem, was a classic ballad of codependency. She expressed a fondness for formal bondage and discipline in "S&M," but usually the chains she described were imaginary. In "Fool For Love," the ballad that closes her latest album, Talk That Talk, she moans the words, "Mama, I found a man," employing the same melody Freddie Mercury used to sing, "Mama, I've killed a man" in "Bohemian Rhapsody." Love is murder, indeed.

In concert productions that unfolded like horror movies and videos that, even at their mildest, showed her as a crotch-grabbing sexual adventurer, Rihanna staked her territory: the least constrained, most perverse corners of the erotic body and mind. "We Found Love," whose lyrics reveal an undertow of despair, was her ultimate statement until "Birthday Cake."

What's upsetting for those of us who admire Rihanna's talent and boldness — and for me as a feminist — is that she has clearly not taken up the narrative of women's enlightenment and self-liberation. Quite the opposite — the story she wants to tell is the one in which the endangered woman doesn't get out, or leaves for a while but comes back, or at best does leave, but can't resolve the mixed feelings she has about her choice.

This is the woman who made "Birthday Cake," and who's invited the man who once so brutally harmed her into its fantasy realm. The song, if you haven't heard it, is very dirty. Originally a short blue interlude on Talk That Talk, it's been expanded into a dialogue, but there's no point of connection, just thrusts and parries that feel as hostile as they are hot.

The song begins with an obscene come-on from Brown, which mirrors Rihanna's last line in the original, but immediately turns the seduction into an act of aggression: "Been a long time I been missing your body," snarls Brown, forcing the listener to recall the reason the couple split. It continues as a series of hissing exchanges capped by Rihanna's dominatrix declarations: "I know you wanna fight this ... It's so enticing ... I'mma make you my b—-h."

As far as seductions go, this one is cold as a walk-in refrigerator. Pushing against a mechanical handclap beat, Rihanna's multi-tracked voice forms another rhythm, like a bully's taunt: cake-cake-cake-cake. Appetite, not tenderness, directs this encounter. It's worse than break-up sex. It's sex with that person you broke up with a long time ago, but can't help hooking up with again, though you regret it every time.

This dead-feeling song may very well repulse you. I prefer it, however, to the bland redo of Brown's "Turn Up the Music," in which Rihanna gives an undeserved assist to an empty-headed club banger. That song plays out their relationship as normal. "Birthday Cake" presents it as pretty damn creepy. Which comes closer to the truth? We honestly don't know, but I know which one I choose to believe, though it saddens and frustrates me.

And can we leave it at that? I think so. It's a hard-to-digest moment in an ongoing story that none of us who write about or listen to music can control. Maybe it's time to search for other narratives. Put on Kelly Clarkson's "Stronger (What Doesn't Kill You)" and scream along. Pick up the phone and call your sister and make sure she's okay. Donate some money to your local women's shelter. Recognize that pain and bad decisions are a part of life, and that those "role models" we pull from the ether of mass culture will inevitably fail us. They are only human, sometimes shockingly so.

Explora otro mundo bajo el agua

La fotografía subacuática es una rama muy interesante de este arte. Imagino que ya habrás visto fotos alucinantes tomadas mientras el fotógrafo se hallaba buceando, pero ¿no te interesaría ser tu quien tomara esas fotos? Aquí te contaremos un poco cómo son las cámaras para tomar imágenes bajo el agua.

Las cámaras utilizadas bajo el agua reciben el nombre de subacuáticas y han sido especialmente diseñadas para sumergirse y tomar fotografías en estas circunstancias. Poseen una estructura hermética capaz de soportar la presión del agua y algunas pueden soportar una inmersión de hasta 40 metros, lo que equivale a unos 131 pies.

Para poder sumergirse estas cámaras se construyen con policarbonato, poseen un visor réflex y objetivos con las focales más cortas, a fin de contrarrestar el aumento que provoca la refracción del agua y permitir fotografías nítidas. Además, las cámaras subacuáticas poseen controles más grandes a fin de que puedan resultar visibles claramente debajo del agua.

Existen varios tipos de cámaras subacuáticas, las desechables, las anfibias y las profesionales. Las primeras no son recomendables pues los resultados suelen ser de baja calidad, las segundas son las ideales para los principiantes, y las últimas, como su nombre lo indica, son las utilizadas por los fotógrafos profesionales ya que ofrecen una magnífica calidad en colores y nitidez.

Estas cámaras no requieren un cuidado exhaustivo, pero es necesario que antes de sumergirlas comprobemos que se hallen completamente selladas y hallamos lubricado su o-ring. Finalmente, una vez salimos del agua, debemos sumergirlas en agua fresca durante unos 10 minutos a fin de remover la sal y los sedimentos marinos que puedan haberse adherido al exterior de la misma. Y, ¡muy importante! no la abramos hasta que no estemos seguros de que está perfectamente seca.

Antes de comprar tu cámara acuática analiza modelos y precios y escoge aquel que mejor se adapte a tus necesidades. Recuerda que si no eres experto no te conviene gastar fortunas en una cámara de fotos, pues probablemente nunca llegues a explotar todas sus facultades, conviene adquirir aquella que sabemos aprovecharemos al máximo.

Algunas cámaras acuáticas son: Pentax Optio (se puede sumergir hasta los 6 metros o con una carcasa opcional hasta los 60m, además resiste temperatura de hasta -10ºC [14º F]), Canon PowerShot D10 y Olympus µ TOUGH-8010 (ambas alcanzan una profundidad de 10 metros y soportan temperaturas de hasta -10ºC). Existen otras marcas y modelos, no dudes en echar un vistazo a las especificaciones de algunas de las cámaras con las que contamos en nuestro blog.

Mira este comercial donde alegadamente encuentra una Optio W90 en el estómago de un tiburón. Recuerda es un comercial pero advertimos puede resultar algo gráfico para algunas personas. Advertimos discreción al verlo.

¿Cuál es la foto subacuática que más te ha impresionado?
