I borrowed a Hensel 2 strobe lighting kit without ever using one before. I spent some time online reviewing info and tutorials, though I'm just trying to understand the basic concept of how to use the lights from a technical standpoint and not setting them up to achieve good lighting with placement, etc.
The strobe that has the cable to trigger it from the camera has a button labeled "Press for options" and it lets me choose a value from 5.0 - 10.
1. What is this value? How do you choose what value to set this strobe to?
2. What is the proper series of steps to get started? Do you meter with a light meter and than based on the light meter results adjust your lights? OR is it better to start with some basic settings on the strobe and than meter?
Appreciate any help and putting up with my newb questions.
