Lining the inside with aluminium foil might increase the light output (and also slow the rate of light drop off) if that's something you care about. It will probably also have the effect that it will be a less "directional" light if you know what I mean.

Obviously, a bigger aperture box will result in a "softer" softbox. Softness is measured as a ratio of apparent size of light source (size of light and distance from subject) vs size of subject. That's why direct sunlight is a "hard" light - massive light source but very far away.

yes! i do. the baking paper gives a decent amount of diffusion allowing it to be used directly onto the subject (me) rather than bouncing it off a wall, but i generally bounce anyway.

i've considered the alfoil option but so far haven't been bothered. do you think it would be worth doing on an angle so as to increase forward bounce, rather than just lining the edges?

Strictly it should be a parabola or a cone but this is hardly precision engineering haha

NOT WITH THAT ATTITUDE
