Hey Daniel, to answer your question about diffusion effects....the best way way I have seen to get diffusion is by using a tiffen fog filter 3 placed under the enlarging lens. If you desire a diffused image where the blacks get really diffused and turn almost "blob like" (i don't know how else to describe it)...then expose and develop to get a very contrasty negative and then use the maximum contrast setting in your enlarger.
