2 way film/tint
Is it possible to use a 2 way film/tint then placed it on a clear glass to create a 2 way mirror?
@jdcallanta yes it is, it’s however not to easy to get a good reflection without spots and distortions. But There is a few who have done some nice mirrors with foil.
thank you for the immediate response. how about working with touch frame. how to calibrate a 70" touch frame on a 32" inches LCD monitor? thanks in advance.
