Exercise - Softening the light

I am using my stuff animals for this still-lift arrangement using reading lamp by the bed as the light source as it is fixed.
I am using 3 ply tissue as diffuser but use 1 out of 3 ply for the first setting and 2 plies out of 3 for the 2nd setting just to experiment the differences. I shot the photos using RAW and JPEG. Photos in JPEG are more vibrant than RAW file and therefore I open RAW and save onto Jpeg again.

Camera setting using tripod
f5, AV mode,ISO100

Photo 1 - bare lighting
exposure 0.4sec



Photo 2 - 1 ply of tissue as a diffuser
exposure 1 second


Photo 3 - 2 plies of tissue
exposure 1.6second


With the diffuser,
1.the shadow is less harsh with less strong shadow on the individual stuffed animal
2.the exposure time has increased.
3.Overall lighting is softer i.e. less contrast.
4.The diffusion was an improvement for this instance.
