Let me tell you all something on this subject
A good topic this for today, here's why, I have worked in the same place as another colleague for over 28 years, over those years i have stayed 100% cine while my mate had kept up with all the technologies including laser disc's, remember those, they were going to be the in thing,along with VHS, betamax, DVD and now blu-ray which has not taken off already redundent because of the looming 4K.
Of late i chat to him and explain to him how my old films are very old technology but still take off the roof with quality, how i can put a super 8 film on any super 8 projector around the world and it will work, no region codes here, i recently added a top range projector for a few hundred quid, yet today in order for him to get rid of his laser discs,& they look new, he looks after everything, he is having to give them away because no one wants to buy them, they are worthless, even on e-bay.
so in very harsh terms to the twats who go on about our old technology answer this, how come they are still going so strong after decades, how come our films are going through the roof in value whilst there crappy technology ends up a few years later in boot sales for next to nothing, and still no one buys them, all those people who bought films on VHS, then again on laser discs, then again on DVD and some replacing them on blu-ray soon to have to do it all again on 4K then 10k and so on and so on.
Yes our technology is old, but the magic of a film show complete with projector and a few marks here and there wins hands down on new stuff built to be superseded within a few years in order to keep the rip off company's in business. You dont get DVD conventions do you?
Whenever i do a kids film show it guarantees there good behaviour as they watch the big screen in awe. Our projectors are all good for years to come and so are most of the movies.
So tell them to stick that in there pipe and smoke it!
