me explcias como se hace una foto tan de cerca sin que salga borrosa y ademas con un efecto de luz impresionante?
niño, siempre sales gruñendo, hombre!
cool shot!

^ Increíble, señorita Martamaulla, ya me reconoce solo con verme el ojo. Dados los maravillosos comentarios que me hace usted, creo que si paso por Barcelona, me prestaré raudo a pedirle en matrimonio, a ver si hay suerte y cuela.

absolutely. of course, mirror reflex...argggh. punching my head ;-)
ok, giving something back now:
for calculating i use this: »link type in your focal length top left (should be still about 116mm) and it gives you the "perfect" (don't ask me why, that's gettin real complicated) pinhole size on the right. put in your real pinhole diameter on the left under focallength, and you get the f-stop. easiest way to measure is either scanning the pinhole with ruler and enlarge to be able to see it or eventually down-calculate from the exposure time you got.
plus adding the schwarzschild-effect....
nice thing about this calculator is you can also see the image diameter, so you can estimate the vignetting - did that with my homemade packfilm-pinhole and the fading came out perfectly as i wanted

^ Thanx, i'll try it!

thx a lot!
so...
- is there still a shutter then or do you do it the "classic pinhole way"= covering? if still there, should be spossible to calculate the f-stop and add some nd-filters to the magic eye to have an automatic exposure pinhole :-)
-pressing the button still triggers the moving out and developing of the pola after removing the lens?
(asking that much cause i have a semi-broken...and am afraid to break it totally without result...)

^ The shutter in the Sx-70 is the mirror that moves inside from the viewer to the exposure position. If you just remove the lens, everything keeps working just the same. I never fully understood the f-stop pinhole tables and formulas, so i covered the fotometer window with black tape and the camera stays opn for about 25-30 seconds (at least mine), another solution is opening the camera "mouth" while the shutter is open, you get the same result. I hope it was useful!

(I'd also be interested in a rough set-up to trigger my thoughts about sx70-pinhole...which parts removed?exposure control?/developing?/shutt er(button)?)
I'm fan.

^ Ok, just remove the front plastic piece of the camera and you get access to the lens, it's pretty easy to remove those and you get the Sx-70 with a 2 cm big hole. I cut a square piece of a cola can and put it on the hole (paint it black to avoid ight lekas and reflections). To make the pinhole you can use anything, the smaller the pinhole the sharper the image, but i wanted to see something through the viewer so i could frame the picture properly, so i made a pretty big pinhole (about 1 mm) The results weren't very good, so i tried attaching lens to the pinhole, and you get strange things: macros, tunnel effects, etc. (You can see all my tries in this gallery) And lately i've tried making a smaller pinhole. About exposure times, i use 600-type film and with the new pinhole i have to make about 30 seconds exposures, or what's easier, use a flash very close (10 cm or so) to the subject. That's how i did those 3 shots.

i wanna learn the process of this

^ I can tell you everything if you want
