Understanding exposure

Returned home today and a new book had arrived. Bryan Peterson "Understanding exposure" - seemed interesting with lots of photos as examples and not too much to read.

So lucky to have got a new book.... another addiction of mine is to buy books. Have a pile newly ordered not read yet
and another pile earlier ordered .. not read yet ;)
Hopefully I will have a long life,
more time
or become a faster reader.
In above mentioned order.
