Ah, no, I see the confusion. Those photos were taken using a white background. The black one was just for a test with the LED lights.
Once I saw that photo on my PC I realized that that particular photo didn't really come out well because I hadn't adapted the settings of the camera when switching between the white & black. So I didn't post the pic with the black background.
I think for the WIP shots I'll stick to white and for the finished shots I'll do both.
