The other night I pulled out my soft box and spent a little time with my favorite models exploring light.
With Olivia I went with a powerful light from a couple feet away to get all of her well lit.
With Mia I pulled the light in real close and powered it down so the light would quickly drop off.
It is pretty amazing how the same light modifier can produce significantly different results. See the photos above and a few more in my Playing with a Soft Box Gallery.
