I noticed Tryg's close-up comparison of the Firehawk material
vs the aluminum paint. They look very similar!
I have been thinking, the aluminum paint must have some hotspotting
no doubt.. and a slightly "diffuse" surface would help to prevent this.
but what if we took some of this aluminum paint, and mixed
it with increasing amounts of a light grey paint..until we get the
right combination of gain & gray.. you know what I'm saying?
this will be relative to each person's ambient conditions and projector..
but mine is a relatively low lumen (400 ansi) with low contrast
ratio 150:1 ... I think it would benefit alot..
I think if I made various samples of 10 parts aluminum, 1 part light grey, 10:2, 10:3 ,etc.. and see if I can find a happy medium of some sorts...
by testing the samples with my projector before I make a big screen.
Just need to dilute the aluminum (it is oil based?) with another
oil based light grey.. maybe..
I'm considering trying this out when I have some free time.
what do you guys think? is it crazy? I imagine I can just spray
the aluminum into a small cup to collect it and then measure it and mix it up with light grey and apply with a roller to some sample sheets...
Is this aluminum available in small buckets??
it will be a bit messy test but with some surgical gloves and plenty
of newspaper... hmmm
