Comments about Datavideo CLK-100 Dual-Color LED Chroma-Key Ring w/Retro-Reflective Screen Kit:

This is a Thai copy of an exisiting system which was invented in the UK.I have an original system, bought a few years ago, and and tested it against this one.

On this system :

- The dual color is a gadget.
- The curtain is a joke (looks like a tent cover)
- The adaptors are useless (very few)
- Very little support.
- Built by a company who doesn't know anything about optics in ChromaKey.
- When you zoom into the curtain you obtain a moire of the video, which renders the system useless in close-ups.

I needed an extension to my existing system, and tried this one.
Result :
I sent it back, got a refund, and bought the original at a cheaper price.

We framed from 22 feet a trademill with people walking over it. Camera bent at 90+15 degrees (vertical framing plus trademill ramp) with the background vertical 6 feet from the subject (28 feet total).
chroma key works perfect even with blue led light and subjects wearing blue jeans!
Total lighting at maximum level is not so much. we had to use an open diaphram (2.8\4). Blue seems brighter than green.
Some glue found on the background produced strange stains we hat to clean it.

Quite amazing if you think about it, yet simple if you really think about it. It is must easier to set this up than a billion lights. I was worried about green or blue reflecting off the subject, but the end result was not noticeable!
