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.

room doesn't have that much ambient light and using the cinema mode. it will be night time use and not during the day. so i just want to know which of these 2 will perform with excellent contrast, colors and black levels. also i need guide of how to mix these paints i tried to follow the BW mix but its an old thread same thing with C&S. Just wondering if both of those mixes have new updates.

While I'm not the expert, (Harp or Mech will surely chime in soon) I think the Black Widow Ultra will work better. They reformulated after the AAA was discontinued. Seems like they have got a new formula pretty much worked out. I'll try & find the link when I get home if they don't beat me to it.

ok, thanks. also do you know which of these 2 have a higher gain? i know that the darker it gets you loses some gain.

You certainly don;t need any gain with your projector and the mounting distance you stated in your first post. At that distance you can have anywhere from a 108-129" screen with the 129" screen giving you 25fL according to PJCentral. What you do need is help with blacks.

Go with BW Ultra™ and use either Dover Grey or Veil as a base. They're listed in the sticky thread here.

do i have to mix this paint with AAA for BW Ultra? are these paints OTS or they have to be tinted into gray? is the mixture 1:1 ratio just like the C&S?

No, that is not correct. The ratio of AAA-F to the base paint has always been 1 part AAA-F to 4 parts of the base paint. That means you would add 8 fluid ounces of AAA-F to 32 fluid ounces of base paint. With the new AAA-F having smaller aluminum particles than the old version, there is a possibility that more of the new AAA-F could be added to increase gain; but that has not been tested yet so for right now I wouldn't recommend it.

Your 120" screen would have ~43 square feet of surface area and the given ratio of paints would add up to 40 fluid ounces. 40 fluid ounces of paint should paint that screen.

No, Liquitex BASICS 'Silver' has vastly different reflective and color properties than AAA-F so one cannot be used to replace the other.
