Anong ratio nang White Paint at Black Paint ginamit mo bro? Sorry wala ako alam sa pag papaint..
Like sa 1 liter of paint ilang drops nang Black he he he.. sorry talaga...
Tantyahan lang talaga. Better if you have an extra piece of plywood (yung pinagputulan ng screen) then experiment on the levels of gray that would be best suitable for your setup. Depende rin kasi yan sa PJ mo and room lighting kung mas maganda ang white or ang grey. Start ka muna with white, kung di ka masaya sa black levels, then saka ka mag-experimento sa grey. Bumili ako ng 1L na flat wall enamel na white and 60 ml Davies lamp black na tinting color. You only need a small amount of tinting color. I just used a barbeque stick and dipped (1 inch deep) it on the tinting color, let it drip a little para matanggal yung sobrang tinting color, then isinawsaw ko naman yung stick sa flat wall enamel and mixed it. Better to just use 3/4 enamel muna, yung 1/4 eh reserve just in case napaitim masyado pwede mo i-dilute ulit with the white enamel to make it lighter. Trial and error lang yan. After mixing, tingnan mo kung ok na ang pagka-grey. You can paint it first sa extra plywood mo then once matuyo, ilagay mo sa harap ng white screen mo and observe the difference (while projecting a movie). Kung medyo kulang pa, dagdag ka ulit. In my case, I needed 4 dippings of the barbeque stick for the 3/4 L ng flat wall enamel.
I needed to repaint mine with grey kasi napansin ko kung white, masyadong bright. Even if my room is totally dark with lights turned off, light colored yung walls ko kaya the reflection from the white screen illuminates the room and washes out the colors during bright scenes. Ayoko naman i-repaint pa ang room ng dark color. Now with the grey paint, tamang tama lang siya at gumanda ang black levels niya. Thinking nga of just selling the 92" Sable fixed frame (cinewhite) that I ordered kasi baka mas maganda pa itong DIY ko since custom painted siya for my PJ setup
Better din to use a non relective material for the black border. Yung una kong ginamit is black na quick dry enamel (gloss black) since yun lang ang meron sa bahay at sarado ang hardwares during the Holy Week. Tinapalan ko siya with black felt paper (4 cm wide all around) and definitely better siya compared sa previous black QDE.
