What would be your reason to use diffused direct light over bounce light when they both create soft wide spread sources.

For me, this usually has to do with the size of the source and the space available.

 

If there is a lot of space, it's often easier to control the diffuse light using using a soft box of some sort with baffles or flags.

 

If space is limited, and I need to have the source up against a wall, a bounce makes more sense as the "source" or the white card can be very near the wall.  But, with the lamp in front of the bounce card, controlling the light can become more cumbersome.  Also, a bounce card is much lighter weight and can be mounted somewhere more easily than getting a lamp and frames or softbox into position.

 

In any case, the resulting diffuse light will look very similar using either method.

 

Of course, these days there are also choices of large LED panels as well that can be placed pretty close to a wall, and additional diffusion material can be placed in front as well...

Yeah for sure, in terms of output and shadow quality, what are the pros and cons?

now of course there's different diffusion materials, so let's just say 4x4 poly board vs 4x4 216 diffusion frame

Depends on how evenly you can fill either with light.

I often find a booklight type setup to look a bit nicer, almost no shadows and a great light quality.

For example for a CU I would use a 800W Joker bounced through a 4x4 bead board diffused by opal frost or 250.

For a direct approach I would use something like a M8 or M18 through Bleached Mus.

But yeah, as already mentioned, it's mostly a choice depending on the space I have.

Also how large your source is.. in relation to your subject..  a huge source will give a hard shadow if its far from the subject.. eg the Sun and us..  greater the ratio softer the source .. thats why you want too fill your diff frame as evenly as possible.. if you dont have the space to get back to fill the frame then book light is going to fill it better and give a softer light.. if you have the space I think its just quicker and easy to go direct.. the quality of the light should be the same..

Do you actually use unbleached muslin as a diffusion or did you mean you bounce with it? It would be a pretty heavy diffusion.
