SF does NOT Hot Spot. It does have a positive gain factor, so the center of the screen...a VERY wide center, can show a variable level of brightness when a solid bright color is photographed. (...especially when "negatively" inverted.") And this is accentuated when a small screen is utilized, and even more so if a very small sample is used, placed at center. Those types of misleading methods are consistently used elsewhere in a attempt to show SF "in a bad light" but in fact, you will find virtually NO other similar commentary elsewhere. And you can be certain there are / have been enough SF End Users on AVS over the last 6 years that if only a small percentage of those had bad reports to relate, this DIY Forum would be inundated. But....it is not, and the very few who wander over 'elsewhere' certainly are going to be "educated" to the way of thinking that is prevalent on a Forum that is desperately trying to persuade any / all comers that their brand of DIY Screen making is the only valid way to consider.
And sadly, yes...SF is constantly targeted because SF is a AVS DIY Screen standard, resulting from a concerted effort to develop a alternative to expensive ambient light screens (...originally the SONY Chroma Vue...), due to a challenge directed squarely at this Forum by advocates of those expensive screens. But...no one else bothered to try except PB-Maxx and myself, and we pretty much nailed it in short order. At the time, a "few" people were engaged even back them at constantly harassing every advanced DIY application we / I offered...and back then, not a single one of them was but adamant that NO kind of application that utilized a reflective base was even worth considering.
It is a all to forgotten reason, that simple jealousy drove most of those comments. Not to say anything with that remark except that because of the exceptional amount of effort and time spent relating about out applications, and the inordinate amount of time spent helping all comers, we did in fact tend to dominate the Thread Board. For some, this "popularity" was intolerable...and our efforts "intentional" as far as trying to "own' this Forum.
Such attitudes are childish...and spiteful, and the type of posts generated and the bile that was spewed proved that. And as time progressed, it became a war of attrition that almost resulted in this Forum being closed. such was the single mindedness of a few people, whose primary goal became not so much ridding the Forum of my applications as much as it was ridding the Forum of me personally.
So those few moved (...or were made to move...) on by the Forum Administration, because as often happens when too much leeway is granted for too long, they took their actions much too far, damaging the Forum's reputation Worldwide (...and that was quite a feat to accomplish...) Of course, I played a part as I was one of only a few who stood up consistently (...with a bulls eye on my chest...) to those who acted so adversely and selfishly, and I would not hesitate to go "Mississippi" on 'em. Yes, I got censured at times when I got a bit to "adamant" at being called names and having accusations tossed my direction, but those others? Whoo Boy! Even after repeated temporary banishment s, stricken posts, and directly posted "Offical" warnings, they not only continued on, they elevated their contentious behavior to the point of accusing the Forum Administrators of favoring a person/s over the other.
Not a smart thing to do. The end result was a "very small" exodus to a location where those few could create a Draconian DIY Forum that is exclusive in it's acceptance of only what is considered acceptable on their terms. Crazily though...the same adverse behavior they felt so free to exercise on AVS is considered to be a "One strike and Your Out' sort of thing "over there". (Guilt driven...no doubt..
So there is your reason/s for the "hate" you read....and it's probably never gonna abate as long as this Forum maintains it's tremendous popularity...and I still draw in oxygen.
Now after all that, on Christmas Eve, let me extend a Olive Branch of sorts (..well, at least a twig sized one...)
A time is coming soon when there will be far less a disparity in how DIY applications are presented. and excepting for missives like this one which try to set things in proper perspective, this Forum and me personally will not stoop to name calling or the degradation of applications or persons just to attempt to garner undecided followers. On truth, a close examination of posts show a lessening of all the adverse posting elsewhere, but as to if that will continue...who can say?
I sincerely hope that the tone (...if not indeed the intent...) of all posts in both locations can be hauled back into a "Happy Place". Aspiring or Wannabe DIY'ers deserve to be encouraged to explore options if possible, but if desirous of simply "gettin' it dun" , also be able to depend upon getting help when needed without dealing with acrimonious postings here or elsewhere.
So as often stated...let's all of us Play Nice, and stay off the "Naughty List".
Oh yeah. Laminate.
Well, there was once a time when any "Hang and Shoot' material was extremely lusted after. and Laminate served to allow people to have something along that order in sizes that most other materials could not. So some of the "less than optimal" aspects were pretty much glossed over. (...no pun that...)
Laminate is very brittle, and it doesn't take much of a miscue to render a over sized sheet worthless...or in the least only good for a smaller sized screen project.
Laminate possesses just enough of a sheen that often there is in fact a "Hot Spot"...which is correctly described as a "small" area of noticeable brightness that will move with the changing location of one's head.
Laminate as a rule demands that a very sturdy, very flat frame be built, one that will not tend to ever warp.
Laminate requires that it be effectively glued to such a Frame using a very thin but strong adhesive...usually Contact Cement. As such, it becomes a case where you get one chance to do it right...or scrap it.
So now...if one has a PJ with lower Lumens, or is using quite a bit of Zoom on a large Screen, many times the "Hot Spot" issue becomes less of a problem if not indeed resolved entirely.
All there rest of the caveats mentioned above deal with actual "building" issues, and if you / one can avoid them all, then yes, Laminate may be quite the serviceable material. And ("...heresy of heresies...) it can always be used as a "Canvass' on which to apply a painted Screen solution of choice should the "raw performance" not be satisfactory.
In the end, if a material like Sintra / Komatex can be had, it completely resolves all the adverse potential a Laminate brings to the table. As a staunch advocate for keeping risks at bay, I'll always suggest such material over a laminate. But when the need calls for a Laminate, then what is required is that the end user be informed and educated as to what to do...and what to avoid. It's really just that simple.
That's about it.....have a very Merry Christmas
......and go eat some cookies. I'm sure they will be easier to digest than this self generated onus.
