Earlier today I purchased a new LED lamp and set about testing it with my light table set up.
I am using my Minolta Dimage Z1 camera 3.2 Mega Pixels with camera set to Macro and varying the light effects and in the case of the last image - the background.
Image 1 - New LED set to cool (daylight) setting.
Image 2 - Same set up but light set to warm light.
Image 3 - Same set up but without new LED light.
Image 4 - Cool LED light set up but with green background.
I think the new light works better with greater clarity and colour definition.
