Any strobist enthusiast out there? I'm trying to replicate the image below but to no avail. I'm using a strip box at about 90-110 degrees off axis but somehow, I can't seem to get the highlight to form a line. Instead, I get an area that is highlighted. I tried to increase the angle of the stripbox (120 to 145), but I end up capturing the box in the photo. Any advice is appreciated!
