# How do I set film speeds ABOVE 400asa on a Minox B

How does one tell the meter that the camera is loaded with asa or iso
1600 or 3200 film? the meter on a Minox B only goes up to 400,
However I suspect that their is a way of lying to the camera.

If you use ASA 800 film, double the shutter speed for ASA400. fOR example, if
at ASA 400, shutter indicates 1/100, you double it to 1/200.
For ASA 1600, quadruple it, and so on.

<p> Alternatively, you may set ASA dial to 400, then fully pull open
Minox B, turn the speed dial, instead of the usually 1/100, you now
turn the dial the 200, and close the camera. Now the meter
is set for ASA 800. For ASA 1600, similarly index the speed dial
at 1/400 ( slightly less then 500 mark )

For 1600 ASA film you can set the "ASA" pointer so that it points to
an imaginary location two stops above the "400" dot, when the shutter
is set to 100. This would correspond approximately to the second
connecting line from the left. The meter in my B is inaccurate by
almost exactly two stops and this is how I compensate.

I think Martin meant to say that you would "halve" the shutter speed,
not double. If the meter indicated 1/100th of a second, cut the time
in half and use 1/200th of a second.
