When you use a view camera for macro work you have long extention on the
bellows.
You then need to compensate for the lost light to calculate a proper
exposure.
Does somebody have an easy way to calculate the exposure compensation?

I am using a 6x9 Linhof and want to play with a 5.6/100 Componon-S.
I guess you don't compensate down to 1m? ......but from here and
closer?

A held calculator with this formula and then you can make your own
"dummy stick"


Indicated F/stop (Use a light meter) * Bellows Extension (Use a ruler)

= Effective F/stop.
