Correct me if im wrong but i dont think the distance of light source from the diffusion creates softer light. The softness of the light is relative only to its size and distance from the subject. Bigger and closer source to the subject creates more soft light which is why the frame diffusion appears more softer than the softbox?
The distance of the light from the diffusion only needs to be enough to cover the diffusion to make it as the new source, which makes it bigger, therefore making more soft.
yes your correct on all of that! having a larger source like a large diffusion frame will soften your light source exponentially. a good rule of thumb is to have your diffusion frame as close to the subject as possible while keeping your key source as far back from the diffusion frame as possible. this will soften your source even more than if the light source was directly behind the diffusion frame. this is why a bounced source is the best way to achieve these results since it can double the distance between your source & diffusion frame while still keeping a small footprint on set! another good example is on a sunny day look at how the sun looks coming through your windows & how natural the shadows appear. then take a light source & have it right outside your window. the shadows will be harsher & less natural. take that same source & back it up 10 ft or so & you will notice how diffused the shadows appear.
