Subject: [Leica] M6 exposure meter problem

Earlier today I scanned a 36 exposure roll of 400 TMY. Every frame was shot 
with the exposure meter on AUTO as recommended by one of our colleagues. 
Every frame was overexposed. 

I bought the M6/0.85 at the end of its production when dealers offered a 
factory authorized rebate of $500 or thereabouts. I don?t remember the year; 
the S/N on the hot shoe is 2433148.

I am thinking of determining the M6 meter?s measurement error by the 
following procedure:

1.  read the exposure setting of my M8 on AUTO of a frame filling exposure 
of my venerable Kodak Gray Card at f/8 and ISO 160.

2.  read the exposure setting of my M6 that would supposedly result in a 
correct exposure of the same card at f/8 and ISO 160. 

3. Calculate the exposure compensation setting or an equivalent increase in 
the ISO setting for the M6.

I will be grateful for corrections or recommendations.


PS FWIW the ?restore colors? setting in VueScan gave an approximately 
correct rendering of the image; the ?restore fading? setting was too dark. 
Checking neither showed overexposure. I will be glad to email samples to 
interested parties.
