A small table with frosted glass lit from underneath,
the lamp shining at an angle from front to back creating the glow and eliminating shadows.
A thoroughly cleaned ratchet socket set arranged on the glass.
A white bedsheet above and behind the set with a halogen floodlight shining through it (sort of light-tent).
A black sheet covering the side and the front (where the camera is) to avoid unwanted reflections and add some contrast.
Image was then leveled, then curve applied to lighten the midtones, colorised with blue hue
(using hue/saturation menu) and then desaturated to make it a soft blue.
The original was more a greenish color with some other nuances in there,
did not look as clean and technical as this one.
