Follow-up to: green screen blues…(blue screen too)
I wanted to follow up with another question to help better understand the facts concerning the blue screening of jewelry.
I’m not sure if I was clear about the jewelry having to glitter or ‘bling’. If I mask aroung it in Photoshop, it won’t sparkle or glitter. My whole idea is to get it to sparkle with a different background.
Is this close to impossible? My guess is, with all the feedback, is to go with the still shots and forget about the motion? I have Boris RED. Could I use that to make it spin? It would probably look cheesy with no sparkle though.
What is the bottom line? Go with a black background and get the best still shot with the jewelry as best as possible? I would really like it to sparkle, but it seems to be quite frustrating to get the best sparkle.I hope I made sense without repeating myself.

The sparkle comes from light reflecting off the facets of the jewels.
Use the black background (Flat or Velvet Cloth), light the jewels for best look and then…
HAND-MOVE a single (or more) ADDITIONAL light(s) around in the air focused on the jewels as you watch the monitor for the best “moving sparkles”.Alternate method is to set up your jewels and background all on a “display turntable” (they are found at supply houses for retailers).
They turn very slowly (1 to 3 RPM) and, if you carefully set the jewels in the exact center of the rotation, you can get very nice “sparkles” as they turn in the light. -
How do I drop a different image or video in the background if I am going to use black as an initial background? To go back to my original problem, would I need to blue or green screen? If so, that would open the old can of worms of green or blue reflects on the jewels.

You keep asking how to do something that is impractical. That’s why we keep offering altgernatives.
Blue/Green-screening is a very “touchy” thing (designed for one kind of purpose) and is simply not suited for shiny or clear objects.
Luminance Key (where anything at or near “Black” drops out like in blue-screen) is a good alternative.
EXCEPT…
The shiny jewelry will have lots of black and near-black reflections (and “clear” sections) that will drop-out as well, so you’re still stuck.
Sorry, but “keying out” live jewelry is just not practical.

Do the ring in 3D and then you can key it over anything. Get a 3D artist to animate a ring AE can add some sparkle and then you can put it anywhere.
Hope this helps-

If anything, Ultimatte should key it for you. It’ll maintain highlights, glows, shadows, transparencies, fine detail, etc. I think you can download a demo. Try it and see what it does for you. It’s pricey and kind of slow but it’s the best keyer out there. I’ve been using it for years and haven’t had a key give me a problem yet. It performs magic other lower-cost keyers just can’t solve.
