Project 65; Symbols

I have had a few Ideas on the themes that were mentioned in the project. They are as follows;
Crime:
Photo of news paper headlines. A ski mask with a gun on a table. A person dressed as a thief; mask, stripy top and swag bag. A wrecked and burnt out car. A broken car window.

Poverty; Begging hands/bowl. Homeless person/people.

Silence;Finger to lips. Someone gagged. Zippered lips.

Growth; Graph going upwards. Person standing on a height chart. An arrow pointing straight up.

Excess; Overflowing bottle bank?
Here is my first attempt at poverty;
And here is something that I produced purely by accident when I was playing with strobes;
It has an almost religious quality to it.

Project 64; Evidence of action

I like both of these and cant decide which one to publish here so have included both.
Before ...

After....

Artificial light. Balancing flash and ambient light.

I have been continuously experimenting with artificial lighting since completing section 6. I have been carrying out one of the exercises recommended on strobist.com on balancing flash and ambient light.
So I chose a subject to experiment on and here it is.
this photo is shot with just ambient light, f4.5 at 1/750th of a second with window light from the left of frame. The light is a little harsh I think and could probably do with diffusion. The shadow detail is poor too.

I placed a speedlight below and in front of the orchid, about a meter away set on manual. I took a series of exposures and reduced the output from it eventually down to 1/16th of full power. The flash head is zoomed fully to 105mm. I got the exposure above. Not a great improvement. The sun is on the left and quite strong. The flash throws a nice shadow on the wall behind and does improve the shadow detail. However the overall effect of the lighting is too harsh.

Here I have moved the strobe above and to the left of the flowers. The power is reduced to 1/32nd and the head is zoomed out to 70 mm. I like the speculative highlight on the green leaf and the shadow fill on the flowers. The effect on the wall behind is nice too, the splash of light.
The exposure is 5.6, 1/125th of a second. ISO 200.

Here the exposure is the same. The flash power is the same but I have placed the clear grid diffuser on, which zooms out to 17 mm. I like the quality of the light, the shadow fill and detail are good. The direction is good too. I think though that the light is too white.
The same shot but I have used the cloudy white balance on the camera to warm up the shot. I dont own any flash gels at the moment and I think that that would make a difference.
Here I have used tungsten balance on the camera. The flash still white as you can see on the background.
A closer shot of the flowers. !/60th of a second at f5.6. Flash is same position and power output.
So I was looking at some of the earlier photos and I thought about the ambient light. I prefer the balance between the ambient and flash with the balance slightly tipped in favour of the flash and the way its splashed on the wall and highlighting the flowers. So I left the f stop at 5.6 and changed the shutter speed to its max which is 1/250th of a second. This has the effect of cutting down on the available light. Something I might try is to cut it even more by using my variable ND filter, a trick that David discusses in a recent post here http://strobist.blogspot.com/2010/06/using-nd-filters-to-kill-depth-of-field.html
I turned off the flash to see how much ambient I would get and above is the result.
Now add the flash back in;
I like the balance here .
