I've not used them but this company http://www.bristolpaint.com/vfx not only sell chromakey cloth but also tins of paint as well which may prove an interesting option to you.
I'm Jo and I've just joined DD in the hope of finding out helpful tips etc - so far I've learned some ace advice, so thanks to everyone!
I'm recently finished my first amaeteur video - a 4 minute music video (an original sound track with my friend miming over it - Was really impressed with it - Sony Vegas just rocks!!
I'm now wanting to experiment more and wish to get a chroma blue backdrop. I don't want to spend the earth - heard that muslin material is good, but was wondering which kind of shops would sell the relevent stuff. Is the actual colour known as 'chroma blue' or is that the name used in videography only? Or is it known as something like 'royal blue'?
Any help would be seriously welcomed!
Many thanks and hope someone can help.
Thanks, Jo - Leicester
I have used alternatives and rarely have I found the results as good a real chroma materail.
I am not sure why but green is used for video and blue for film.
Originally blue was used because human skin (orange) is a mixture of red and green. Also film wasn't all that happy with green and the green layer was the least sensitive. Also in film the blue sensitive layer is the top layer so (in theory and being unbelievably anal) it should be the "sharpest".
That's not such an issue nowadays. Green is now used almost universally (film and video) because (a) a lot of men in suits wear dark blue and (b) the "green" chip in 3-chip camcorders is the most sensitive.
