How to use negative values

[Phil Harvey]

Ah ha!  Now I understand!

You just wanted to set the value to a negative number:

-exposureadj2=-0.25

Simple.  I was confused because I thought you wanted to decrement the value.  The += operator is used to increment/decrement values.  To simply assign a value, use = (this works for negative numbers too).

Hi Phil,

Cheers, not your fault, I was making assumptions and came to the wrong conclusion.

Now I know a lot more about what can be done with adjusting the exposure value.
