Pocket Pixel: Herramienta para light painting

Hoy os quiero presentar una nueva herramienta para fotografíar con la técnica Light Painting. Se trata de un dispositivo compacto para ser usado con una sola mano, pensado a grandes rasgos para dos tipos de funciones distintas.

Por un lado se puede usar sujetándolo con la mano para dibujar formas de distintos colores y su otra función es para dejarlo fijo en el interior de una habitación o casa para iluminar de un color toda una estancia mientras hacemos la foto desde fuera.


  • Dispone de un botón on/off y 3 botones para usar los distintos modos.
  • La superfície cuadrada que ilumina mide aproximadamente 5,5cm x 4,5cm y produce una luz LED difusa.
  • Se alimenta con 4 baterías AA a través de un portapilas integrado en su caja.
  • Dispone de dos pequeños imanes a los lados de la superficie que ilumina para añadir posibles accesorios que cambien la forma de la luz o incluso añadan difusores de formas distintas.

Making of "Ephemeral dreams"

To create this work, I mixed a 3D rendered labyrinth with some photos. The final photo is composed by these three kinds of images, created in this order:

Hands: I used a Canon 17-40L lens at 17mm, f/20 to get a lot of dof and flash on the right with a small softbox.


 Sand falling:

I needed to get some photos of sand falling and merge them together to create the parts where the labyrinth was melting. My photoshop skills are very limited so I had to get a good perspective and shoot at 17mm too in order to facilitate the edition. I did some tries using a shutter speed of 1/30, also f/20 and natural light to get a kind of “silk effect”, but when I joined the captures with the 3D labyrinth, the result looked like plastic. I repeated the sand captures using flash to get the opposite appearance (freeze the motion), and I stuck with that setup for the rest of the photos I needed (just 3 or 4).












Labyrinth: Modeled with 3D Max 2014 with iray. First I created in Photoshop a 2D image in black and white with the labyrinth I wanted, until I got this:


I added some layers and used the gradient tool to darken the corners so that the labyrinth appeared that was melting when applying later the “displace” modifier in 3D Max (depending on the shade of gray, the height of each wall will differ).

Then in 3D Max, applying the modifier “displace” I used the displace map created to get the 3D appearance. With the modifiers melt, noise, wave and bend I added some imperfections, and also edited the mesh of the labyrinth to melt much drastically the middle part and the sides. Result:


Each part was processed with Lightroom to add some dramatism by using clarity and blacks, and changing the temperature of the captures, and also desaturating to have a similar appearance in all of them and facilitate the Photoshop part.

Making of "Captivity"

In this one, I wanted to create an mood similar to a jail by projecting the light through something like “metal bars”.
I used a cutter and cardboard to create my bars and set a flash behind it on the right of the camera to project the shadows of the bars onto the composition.

I could have created shadows with a more defined borders by placing the flash farther from the cardboard, so that the relative size of the flash would be smaller, but for me it was ok this way, because it can be interpreted as an office curtain too, which I also found appropiate.

To emphasize the highlights and textures of my hand and give the impression that the person was in tension and sweating, I used a dropper with water to wet my hand. I used an old keyboard I had at home because by combining it with the b/w processing seemed more adequate to me than a modern keyboard.
