Magnifications

One of the main purposes I had behind magnifying commercial screens and DIY screens is to compare quality to DIY offerings. Why? To see where DIY is at compared to commercial. I've always stated that the current crop of DIY products is only 90% of the way there and they'd never get the last 10% mainly due to better quality control at a screen manufacturing plant as opposed to someone's garage.

DL Glass Beaded Screen



HoloDisplay's HoloVega 200x



DL Silver Vision 200X



DL Silver Matte 200X



DL High Power 200X



DaLite Silver Matte at 10X



My Pigment Free Gray experiment.



Silver Fire





CMRA's S-I-L-V-E-R



Pearlizing medium over both True Value Winter Mountain and Winter Mist. This is the 1X formula applied once. The current recommendation is a 2X formula rolled on twice!





To stress again how bad of an idea this really is, here are the spectral curves for Winter Mountain pre-topcoat and post-topcoat.





If you look closely at each of the images you notice several things. For example the size of the glass beads from the High power and the Glass Beaded screens, the texture of Silver Matte, etc. What really stands out is the difference between the craft store paints and the manufactured products. The DIY screens which add mica to their mix have little specs of blue, red, yellow, green, etc. You do not see that in any of the manufactured screens or, for that matter, in my rendition of the PFG. The light hitting the screen is reflected back accurately not shifted color-wise.
