Contrast and shadow fill.

Photographing an object as with a still life. Using a modelling light, eg Flash or tungsten- key light
And the use of a silver reflector at different distances, to show the how the shadows can be filled.
11 photographs:
The camera and lights are set at right angles from each other . The camera at same level as the subject, and the light shining from one side .
First photo taken as.

1 / without diffuser
2 / With
3 / with white card reflector on opposite side of lamp 3ft away
4 / the same with card 1.5 ft away
5 / this time using the same size reflector, using dull side of tin foil

. A Simple exercise gone bad. I was using a 283 Vivtiar flask on M f16 mains powered. As tungsten lamps are hard to find here in borneo at a reasonable price.
After 3 shots it packed up.
So I charged up the Metz . Again . to use for this exercise, Auto mode or set to F stops does not work, due to the computer adjusting the light. So on Manual, the batteries drained to fast.
Frustration ! Only my Landlords Blue lamp.  trying to set this up with there energy saving bulb was getting to much. Then SMASH on the floor it went !

So now faced with no lamp, no strobes, have to wait for the shops to open to buy a replacement, and some sort of lighting to do still life table top photography.

11 photographs: It does not explain what other photographs are required to make up the 11? Or does it say continue to use the diffuser over the Key light.

The following picture were re done. The next morning using a metz C45 Set to M giving an exposure setting F stop of F18 . Camera and flash settings did not change through out the shoot. 

Would I be right to do this:

6 / Same tin foil dull side 1.5 ft closer
7 / Same tin foil using bright shiny side 3ft
8 / Same this time 1.5 ft 
9 / Same using crumpled flattened tin foil 3ft shiny side 
10 / Same as 9 but 1.5 ft closer. 
11 / ????   I think take with diffuser and as 10

Clearly showing the dramatic change in shadow and contrast , When using a diffuser and a reflector makes highlights softer showing detail. Shadows show detail also. Yet the picture still holds texture and form.
picture 2 and 11 are the best here.
