and I will just go ahead and ask and really show my noobness to this, but here goes. How exactly do you meter when you get your lights set up? Is it a lot of trial an error?
A strobe meter is a great addition, however you can also do a trial and error setup. Shoot a series of exposures at various f/stops at say 10 feet. Choose the best exposure (histograms are O.K. but, I prefer to use my computer monitor). Shutter speed will not matter, usually for studio work I keep my shutter speed around 1/60 second and shoot in manual exposure.
Multiply the best f/stop number by 10 and that will give you the correct guide number for that light - set up with that light modifier such as softbox or umbrella. Guide numbers were the way photographers calculated flash exposures before the advent of through the lens flash metering or thyristor flash metering.
Say that the best exposure for your light and light modifier is f/11, the guide number for that light will be 110 (10 x 11 = 110). You can then determine the exposure for other distances by dividing the guide number by the distance in feet. As an example at 5 feet the exposure would be f/22 (110 divided by 5 = 22). This works at just about any distance up to the maximum range of your flash.
That's how us old codgers determined our exposures manually using flash. Of course, we soon cut corners and learned the exposure for head and shoulders, 3/4 length and full length portraits and also the exposure for groups of two people (since you were usually at the same distances whenever you shot these images.
When you have gotten used to using your flash units, you should be able to guestimate the exposure pretty closely. Additionally, since you will have variable modeling lights on your studio strobes, you can eyeball the lighting ratio.
After you use your lights for a while, exposure will be second nature but, it is always wise to take a couple of test shots. A always have my notebook computer in my studio when I am shooting to check exposures.
There are however, some relatively inexpensive flash exposure meters. I use an older Sekonic L408 Flash meter which I have had for almost ten years. It works just great. It doesn't have all the bells and whistles of a more modern meter but, it runs less than $100 used on eBay when you can find one. This meter also works as an incident light and reflected light meter for continuous light sources and has a spot meter attachment.
