I am pretty competent dealing with copper pipes carrying water. Are copper gas pipes pretty much the same? ie is it just compression fittings for the connections? I need to fit an electric oven with a gas hob
Try Photo Shop instead of Chroma Key. Using a digital camera and Photo Shop can produce the same effects if you start with a simple solid colored background. I've included a link to my web site, theahrensimage. Check it out, several of the images under Portfolio - Children and Seniors were created this way. The full version of Photo Shop is expensive but very much worth it! Learning the program is time consuming but there is so much that can be done with it. Good Luck!!
Light doesn't decay. Decay only happens to objects subject to the Weak force or the Strong force. Light can be stopped by thin material, which then dissipates as heat into the surroundings.
