These are two I tried with my 6" beauty dish.
I think I need to find full sized "models" though to properly test it on.
I too tried a few test shoots when I first heard of the idea - still tempted to give it a go myself.
I've a couple of the Godox AD360 units, so I tested it out with one of those with a few different light modifiers:
- 30cm Beauty Dish
- Gridded 30cm Beauty Dish
- 48cm Octobox
- Gridded 48cm Octobox
I believe the flash and the octobox are the same / similar to that in Dan's setup.
Both the gridded softbox and beauty dish were excellent at controlling the spill of the light, meaning very dark backgrounds from the outset, but I worry a little as to wether they will effectively illuminate enough of the torso when shooting Cosplay.
The beauty dish produced a more contrasty image, more shadows on features etc, than the softbox, but again with a tighter circle of illumination, where as the softbox was better at illuminating the subject overall, albeit with more spill, and produced a slightly 'flatter' image.
If I were just doing headshots - I think I'd go for the gridded beauty dish, but Comicom is more about the costumes overall, so I think that perhaps forces the softbox, the trade off being more work in post.
The one thing I would say is it doesn't take long until holding the flash start to feel like your hoisting a baby elephant into the air!
Camera wise, things have moved on and it's a toss up between the XPro2 / XT2 with 23 or 35mm, or the X100T with 23mm fixed (35mm FF equiv). I think I'm leaning towards the X100 because of the leaf shutter, which will allow me to keep the aperture open a bit. On the XPro/XT2, the max sync speed is 1/250, so that forces an aperture of around f/14, which I think is starting to push the limits of the lens.
If I can persuade my good wife to stand around for a bit this weekend, I might have another go and see what I end up with.
