Long post so I'll give my disclaimers first - no connection to either
vendor, just research and some good experience.
Two links to try:
I use the jewelry photography kit from EZCube/tabletop studios. For
a very reasonable price they supply 2 light boxes, acrylic
platforms, a white drape and 3 studio lamps (get the long-legged
ones, no extra charge) with daylight balanced bulbs. Instructions
are included. I'm still experimenting but have been able to
supplement my pro photos with pretty good home shots. I think with
practice the potential is there to get excellent ones. I use a canon
powershot A95 digital camera or my old nikon coolpix.
The only item I'm using to supplement the package is from Tallyn's,
the second link. I bought a jet black to white graduated backdrop to
get a look closer to the pro photos. Just arrived in the mail.
I'm all for saving money but also time. This light box has two
zip-open sides for direct lighting & top-down or straight-on shots.
It also allows for nice highlights when you want a shine and side
lighting that shows relief. I think the price is worth it for the
lights alone, actually.
Anyway, my 35 cents. Good luck!
