Gotta throw this in here;
I picked this up today... sorta thinking about building Snowy (the wife) her "light box" for taking pics of digs, but I had me a different idea when she wanted me to create something that would keep the light focused, enclosed & centered without casting any shadow... and lit up from at least a couple angles.
My first thought was, "why not surround the target with light, instead of just from a couple angles?"
Well...
This adjustable, desktop, clip-on light, I found at the local Lowes store up here in Maine. It's the closest I could find for the idea that I had in mind. I kinda was hoping for something with a bigger circumfrence/diameter, but ya gotta make lemonade when you're dealt lemons, right?
Anyway... this thing had a magnifying glass in it (which I promptly took out for allowance for the telescopic(able) lens of the camera... which isn't really needed, since you can get very close without zooming at all anyway)... but a picture is worth a thousand words, so here's an example of what I got with this "ring light" idea:
