So heres what I did today. Had less time so just small bits of work done.
First off, the tint paper 3M was not available in Peshawar. So I got the best possible available. Some Korean paper the shopkeeper said.
In the pic below, you can see the comparison. One portion tinted and the other not. Btw, I also tried using a paper with much lesses tint value, but, instead of giving it a smoked out look (that we all want) It looked as if the light compartment is dirty from within.
