Hi Rob, as requested:

Camera - Nikon D300 on tripod with cable release and mirror lock-up (reduces vibration at shutter release)
Lens - Nikkor 105mm & 55mm AiS macro (old type manual focus) with Nikon PK-13 & PN-11 extension tube for extra close-up shots. 55mm used 90% of the time.
Setting - RAW, aperture to suit, shutter speed as required
Lighting - 4 x 600x600mm surface mounted fluorescent fittings fitted with daylight balanced tubes (one on each side of the subject, one below and one above) and all covered with trace to diffuse the light. These fittings are commercial units often found in suspended ceilings but the surface mounted variety, which sit nicely on the worktop. More often than not I use just one sidelight and lots of reflectors (bits of white card and paper including a piece around the lens). It can get a bit messy at times. Also lots of blue-tack to hold things in place.
Processing - Photoshop CS4 (the final and crucial ingredient). Elements is also good and much cheaper. Besides the basics (cropping, levels & sharpening) the colour balance is essential because the lights give a cold blue/cyan light, which is easily sorted in PS.

I have a "studio" set up which is basically a 900mm wide cupboard with a worktop.

Regards
Paul
