Flight: Spain: La Cerdanya in Infrared / en Infrarrojo

Castellano abajo.

I am interrupting my crazed need to post images in the relative order taken to show off my latest toy: an infrared camera! It’s a process to get the existing camera converted, as some internal optics need to be replaced, focus calibrated, and white balance settings toyed with. That all done, along with paying fascist import fees and a bunch of other rigmarole, it came in yesterday and I tested it today in the airplane.

We can’t see infrared, that is obvious. The camera can, though it has to convert it to something visual for us to see. It usually comes off the sensor as some hideous tinted red, of which is overridden by the camera white balance settings to make it fairly close to white. In the end, my presumption is that I am getting a binary image. White = IR, black = no IR. The result is very Ansel Adamsesque.

It has the added effect of seeing through haze. For anyone paying attention, I rant about it rather frequently, so now I have a tool to photograph on days that otherwise would be labeled crappy. This I proved today, going up with tons of glare, haze, and bleached lighting. The IR perspective eviscerated the disagreeable parts.

White balance off the camera presents the sky a tinge sepia. Some images I keep it, some I don’t. I am still making up my mind.

You’ll observe many interesting facts about IR. Roads absorb as opposed to reflect. Deciduous grasses and trees reflect most of it. Pine trees and shrubs reflect only some. Tilled soil reflects a small amount. Rivers and Spanish roofs reflect almost none. Clouds reflect a decent amount, though not as much as foliage.

Estoy cambiando mi proceso de publicar fotos en el orden tomado para mostrar mi juguete nuevo: una cámara de infrarrojo. Es un proceso específico para convertir la cámara, exigiendo cambios de vidrios y otras cosas para llegar a una foto bueno de IR. Ayer llegó la caja de los EUA, y hoy día tuve la oportunidad probarlo en el avión.

Es obvio que no vemos infrarrojo. La cámara tiene que convertir lo que ve a algo que podemos ver. Normalmente, sin modificación, es una imagen terrible lleno de tinto rojo, lo que está corregido por balancear el blanco. Con esto, el resultado es más o menos blanco y negro, de estilo Ansel Adams.

Tiene el efecto de ver por la calina, un sujeto que siempre estoy gritando de una forma u otro. Ahora, días que normalmente estarían puteados pudieran tener buen éxito. Probé esto hoy, con resultado satisfecho.

Observarán algunos efectos de IR: calles absorban IR en vez de reflejar. Hojas caducas y hierbas reflejan casi todo, mientras pinas son en medio, y suelo fresco aún menos. Techos españoles (o és millor dir catalans?) y ríos absorban casi todo. Las nubes reflejan bien, pero no tanto como visual.
Riu Segre is black. Bellver in the distance.

A little bleaching, though it would make sense that the hill is uniformly reflecting high IR content. In color, its more varied.

Puigcerdà in the distance. République Français on the horizon.

Between Das and Urús. I am leaning toward keeping the sepia horizon – as it comes off the camera.

Bellver de la Cerdanya

Note upper right – a little bit of snow. At least that reflects nice and white. Looking forward to winter already. 4.5 months til first mountain snows!

Lower Cerdanya. In a visible image, road is bright, everything else is dark. IR is inverted.


Looking down the runway – center of image. / Mirando al aeródromo, al centro de la imágen.

Visible image from separate camera compared to IR. Post processed as best I could. Very hazy day.
