Last weekend, we shot a bunch of photos of my friend Sue, a musician and singer, for her website. This was the first time I really got to use my new Sigma EF-500 flash. A lot of the photos came out fine, but some came out really dark. Here are some samples. The first two are dark, the third is too bright and the fourth looks good.
