Sony camcorder set on Macro & a 5000k daylight bulb most of the time. sometimes I just use a 100 W bulb, sometimes both, depends on the marble color. Sometimes only a 30W daylight bulb, That's why you see such a wide variety of casts on my mibs. It can be verry time consuming believe me. Good thing we don't use film anymore, I couldn't afford it
mine looks like this but is older and a 54x zoom with macro, i have a tripod or 2 and a pushbutton remote shot taker for close ups (holding still)
