This is COMIC(AL)

Well, not that funny, actually... Echadle un vistazo a la última respuesta del "buzón": es importante... Aunque me temo que serán LOS QUE NO NECESITEN LEERLA los que la lean, de hecho. En fin...

MOEBIUS (Jean Giraud)

He was one of the most original, innovative, accomplished and hallucinatory artists of the last century. But he was "just" a comic cartoonist, what a pity!... Obviously, I am joking... 
    These days, when some sort of silence is needed more than ever (when, actually, silence is back... see "The Artist"), those Moebius frames, those limpid, airy and enigmatic wordless frames, should be "compulsory" for us all to look at, once in a while: just a few minutes, each and every day, to help us dream... He left us just a few days ago. May he rest in peace.

THE CAMERA OBSCURA

May I introduce you to my own hand-made camera osbscura?... You will discover how simple it is: nothing but a wooden box with a lid on the top of it, a very cheap biconvex lens and, opposite this, a movable frosted glass; and the glass must be movable in order to set three different focuses (from a few meters to the infinite). The interior of the box is painted in black.

As you can see in these photographs, you can manually change the diaphragm, so the light coming into the box increases or diminishes, depending on the diameter of the "pupil". 

That actually changes the sharpness (rather the "Depth of Field") of the images: the smaller the hole is, the sharper the image becomes.
    There is a nut (see meaning #2) under the camera in order to screw it on top of a tripod.

The images on the frosted glass are inverted (upside down), and the same phenomenon happens inside your eyes, on both retinae. Amazing!, isn´t it?... 

Algunas preguntas en español:

1. - ¿Cómo se dice profundidad de campo en inglés?
2. - ¿Qué es la profundidad de campo en óptica y fotografía? (try to find out)
3. - ¿De qué manera podremos modificar la profundidad de campo de una imagen? ¿Tiene algo que ver el diafragma -el iris- de la cámara con ello?
4. - ¿Cuál es el plural de retina en inglés? ¿Por qué crees que es ésa palabra, precisamente?; ¿de dónde procede?...
5. - ¿Cuál es la "retina" de esta cámara oscura?
6. - ¿Funciona el ojo igual que una cámara oscura? Justifica tu respuesta
7. - ¿Qué es un frosted glass?
8. - ¿Cuál es el procedimiento para enfocar la cámara a diferentes distancias?
9. - ¿Por qué crees que la cámara está pintada de negro en su interior?
