When it gets really cold, the first thing to stop working is my peripheral nervous system. And not the sensory part.

Ah, that makes sense then. You get 1000 points for shooting film, 500 bonus points for shooting medium format and 1500 extra bonus points for manually calculating exposure. Those Enablement points are redeemable at any time and have no expiration date. To cash them in simply start a thread with the phrase "Should I buy ". The Pentaxian Brotherhood will provide you with several compelling arguments for use on yourself, your spousal unit and/or the Asahi Finance Co. Tom Reese

I was using my 6x7 at the time, which has no built-in meter. I'd bite the arm off of anyone who tried to take away my in camera spot meter. Ditto for my external spot, and the centre-weighted meters in my other cameras :) Cheers, - Dave

It didn't take me an entire roll to see my screw up. It took me about 8 frames. My "doing it the hard way" comment was in reference to your calculating the exposure compensation for the tubes instead of using in camera metering. I'd bite the arm off of anyone who tried to take away my in camera spot meter. It's invaluable when doing the kind of work you're doing. Tom Reese

Note to self
When using extension tubes with an external meter, don't forget the exposure compensation. Especially if you remembered it for the first photo in the sequence. - Dave "2 stops under"
