M7 Metering Overexpose Compared to M11

Luckily, we have our own process.

In my case, after years of learnings, I make my own (unique so not transferable to anybody) process.

Still learning though as I can not find "one process to do it all".

Photography is a hobby for me, happily as I'm never certain of the results.

I take as example L. de Vinci the Creator of Mona Lisa who "worked" on the painting untill his death.

Guessing, film versus digital meter calibration.  Film is over-exposed a bit for shadow detail, and handles over-exposed highlights well.  Digital a bit under-exposed to protect from 'blown' highlights.  IMHO.

As someone else already mentioned in his excellent detailed post, you don't know if ISO 400 on the M7 (for example) is the same as ISO 400 on the M11.

The M11 also uses a matrix type meter, while the M7 is a fat spot.  There is a lot going on behind the scenes when the M11 meters a scene - with the M7, not so much!

All that matters is do the pics look good?  I would never benchmark any film camera against any digital camera as film looks different than digital.

sensor is different from film

film curves have toe and shoulder regions, not sensor

Sure it is the same for the meter! The definition by light values is independent of the used camera, it is always 0.91 lux s (lux second) for ISO 1 (and, since ISO is linear 0.91 lux s / actual ISO for your actual setting or film).

What the film or the sensor make out of this and what range they accept is a different question, but not the actual topic of the OP‘s question. The OP is originally only asking why the two meters show different values.

Exactly! And that is the reason why simply pointing the 2 cameras somewhere won‘t work, a flat, even and evenly illuminated surface would do the job😉

That is it what really matters 😎

I would not even benchmark 2 different film cameras or 2 different digital cameras against each other. There are always small differences by at least 1/2 stop.
