no one image at a time not the whole fiche!
My mistake, somehow I thought you were trying to do one fiche in one go!
I have just done most of one fiche the
squint down the eyepiece
move fiche to fit
press button see if it can focus, repeat move till focus got
take pic hold
still 4 secs
is a crap user experience!
That I believe :-) But I'm sure you can rig up something to hold the
camera still and in a fixed position relative to the fiche, also held
still and flat. Even a wooden frame if you don't have a suitable tripod
that can look straight down onto fiche on a makeshift lightbox. The
tripod screw on any standard small-format camera or DSLR is a 1/4-inch
Whitworth thread, and although that's not a common size in the States
(other than camera shops), camera shops and secondhand shops here often
have odd tripod screws as spares or off surplus pan/tilt heads or cheap
ball heads or light fittings. I'm tempted to suggest if all else fails
even a 1/4-inch 20tpi UNC is pretty close, but it's a slightly different
thread form and could damage the camera if overtightened.
did you notice the qty in my other reply,
6k fiche say 71 images per fiche if we take the rrd53 as an average
and 8 secs per image
3408000 seconds of peering down the eyepiece getting backache
So finding some way to keep the camera still, at a constant distance
from the fiche, etc is essential :-)
If the fiche is on a lightbox or something similar, tape a strip of
plastic or wood onto the box, and slide the fiche along that to move
from frame to frame. At least it will keep it straight
and and you only
have to worry about one dimension (X) instead of three (X, Y,
camera
distance). Low tech and easy. Of course the plastic strip needs moved
for each new row on the fiche, but a little ingenuity and several narrow
strips solve that.
