I haven’t posted a technarticle for a while, but I thought that this would be helpful
My buddy, Achmat over at Digital Effects recently got some studio strobes and invited me over to come check ‘em out. He was worried that he was having to correct exposure of his portraits in post product. We took some test readings with his Minolta meter and my Sekonic L-358….there seemed to be a discrepancy

I know of one method to test my meter, which is to set up a test shot against a gray-card and checking the reading on the histogram on the back of my camera:
- If the data band falls in the middle of the spectrum, then I knew the meter was spot on!
- If the data band falls to the left or the right of the spectrum, then the meter was under- or over-exposing.

Well, tonight I pulled out a Hensel strobe, set up my Lastolite white-balance target, metered the strobe to 1/125s @ f/8.0 and pressed the shutter:

Looks like about 1-stop under exposure (the band is to the left of the center) Then with with the meter set for -0.6 exposure compensation, I adjusted the strobe until I got 1/125s @ f/8.0:

Ahhhh…much Better!
