Proper diffused light can only be got from a very large light source.
Covering the flash with tissue does not increase the light source
size, so basically all it does is to decrease the flash guide number.
(Tissue *is* useful when using direct flash with a wide angle lens
that can't be covered by the basic flash).
A large light source can be got by bouncing the flash from a large
surface or through a large diffuser.
Unfortunately the tissue "myth" seems to have been perpetuated like
the idea that focal length affects the perspective - it does not. Only
camera to subject distance affects perspective.
