Metering light

I use a Spot Meter for almost all my work. However you also need to use

Yes the average Caucasion skin is a one stop increase in exposure.

If the average caucasian palm is 1 stop lighter than 18% grey, should
you not decrease exposure by 1 stop after metering palm? The orignal
post ask if you would read palm and then open 1 stop.

The original post was correct. The caucasian palm is brighter than
18% gray, but the meter assumes it IS 18% gray with lots of light on
it, and so reduces the exposure to make it become 18% on the film.
You open a stop to put it back where it belongs.
