i need some suggestion to get the best contrast, colors and black levels for diy screen. i've search the forum for C&S Ultra and Black Widow and i'm a little bit confused on what paint should i go with black widow with the new formula of AAA or if there's an alternative to use other silvers besides the liquitex basics silver for C&S Ultra. can't decide which of these 2 diy screen will give best results on my screen. i have optoma hd25e projector and projecting to the wall about 14 feet distance. i need to know if i should go with C&S Ultra or Black Widow.
