A little experiment with big options . . .
A wanted some small objects clearly superimposed against a different background - Blue Screening? - Now where did I see a blue screen recently? My laptop screen! You got it! Supported the objects on the end of a pencil, rested against the blue screen part of "My Desktop" tft of my laptop. Took some footage with my Canon XM2. Uploaded to my graphics editor. Got rid of the blue and produced a perfect "Object Mask". I may progress to moving objects and do a proper "moving" Chroma Key - "Small is Beautiful" - yeah?
I may progress to "Things on Strings" or "Super Rubber [US=Eraser!]" or "Super-Heroes of the Office Worktop!"
