fabrics

Hi Gene,

	Yeah this really is a problem with black fabrics.  I find sometimes 
with black polyester fabrics you can see a visible red cast if you 
are looking for it.  I've also noticed that black denim is usually ok 
because its dyed with a blue or green based black.. Natural fibers and rayon are often 
dyed with a bluer based dye but there are many exceptions. Nylon can 
go either way and polyester is almost always gauranteed to be red 
based  So I guess in short some black fabrics I can tell by looking 
are not going to work, others are a crapshoot, a very few I can 
notice a blueish or greenish cast to them and I know will work

	The best thing if you know you need black to be black for sure is to 
take the camera to the fabric store and cut a swatch for each frame.  
Or just get clothes and fabrics that are blue or green which are 
certain to be black.
