Gradational lighting question ?

How can I put the light on small products gradationally & beautifully? (ex. watch, earring)
It's easy for me to flash a fading light at big products (ex. phone, mouse or keyboard) through standard reflectors & tracing papers; however, my studio flash(25~400w) seems too big for small object, especially, surface of this small product is absolutely plane.

Is mini spot helpful for this subject ?
Or fibre optic is better ? is it ?
Can I make a opaque paper w/ small holes to duplicate similar effect ?

Do you have a light box? Point a couple of strobes at that, maybe not on full power, ISO100 and F32, you'll be fine.

Light box ?! no, I don't like it, 'cause it has no change of lighting effect and is hard to create a painting light.
I replace it with big size of tracing papers so that I can control the distance and direction between papers and objects, papers and strobes.

Narrowing the aperture seems helpless for fading the light, only reducing the EV.

A diameter of light spot seems the key point, but I'm not sure.

Yes. Depends on how much you would use it & if it would pay off in time/convenience? Alternative would be to buy a cheap AC strobe & put a toilet paper roll snoot over it. I got one used for $5.

Me either for some stuff. For anyone else reading: In ** IMPORTANT LINKS: Studio Lighting **, you'll see FAQ - Studio Lighting that leads to some of my threads.
Look at the lighting used in the Browning & knife threads.
