I'd like to thank you for providing the basic tchnical/equipment details of modifier, distance, light placement angle, f/stop, and so on. I think knowing those things really helps people who look at the photo and then can roughly correlate the results with the stuff used to make the picture. I personally LIKE the smaller 24 x 24 inch softboxes and have several. At closer distances like 4 feet, they have a pretty rapid degree of fall-off from highlight to shadow, so the exact placement of them, or the subject, makes a big difference in the lighting result. Moving them BACK, farther away, they have less of a highlight/shadow difference, and in the case of this shot of Logan, if the light had been at say 6 feet, you might have gotten that little bit of light on his hair without needing a reflector, or post-software dodging.
And the thing is: using a single, 24" softbox, you're really learning how to light, precisely, with a light source that creates a real, defined, noticeable direction to the light. These days, so many people want that 60" or 72" modifier...that big, soft, mushy "wall of light" that comes from "the east coast of North America" or "the west coast": but that doesn't reveal much about how to place the light exactingly. The 24" box is the Zombiesniper modifier; the 60" and 72" box is the Zombieshotgunner modifier.
I think learning to light using a single, smaller modifier, like a 24" square box, or a 30 or 32" diam,eter umbrella, is the way to start out. it's more-exacting, and it SHOWS what the light actually does, without much doubt. Ther smaller modifier shows where the light was, and how it hit. I personally think this is the best way to start out for many types of shots, with one, smallish modifier and a simple subject.
