The simple ideas
are the best. <3
Are you regularly forced to sit through 3D kids' flicks in the cinema, generating inevitable headaches and eyestrain, powerless to do anything except hide behind your popcorn and cower at the daunting visuals? Next time you're dragged into such a situation, bring a pair of these along and convert films back to their regular …
You pay extra to get into a 3D screen, suffer the fuzzier and darker picture with poorer contrast, and have to wear uncomfortable specs (over your own glasses, in my case), all so you can sit with someone while *they* "enjoy" the 3D experience while you *don't*?!?
That someone had better be worth it, that's all I can say......
You can already get polarising lenses in prescription glasses. Eventually I expect they will start offering prescription glasses with polarizing lenses which match the polarisation used in cinemas, which is a logical progression from where we are at the moment.
I would pay (not much, maybe £10) for a pair of real-d glasses that would survive more than a few cleanings.
prescription sunglasses use linear polarisation. Real-d is based on circular polarisation, so no, your next pair of prescription glasses won't work in a cinema.
(a correctly chosen linear polarisation angle helps to reduce reflections from things - one reason it is used.)
Incidentally, IMAX 3D (disclaimer: London IMAX near waterloo, other imax cinemas vary.) uses linear polarisation. if you tilt your head, things go crazy. even if you keep your head dead flat, there is image cross-talk. The image seems smother because it is being projected from two projectors at once while Real-D uses one projector and switches the polarity of the filter.
I'd like to see a setup using two projectors and circular polarising filters - I'm hoping for the low (I've not noticed it) cross-talk of real-D and the smoothness of IMAX.
Mine is the one with the notes on a napkin for adding 3D to a home-built projector
Exactly the post I was about to make. Are you plagiarising my brain? :)
The only time I will see a film in 3D is if it's not possible to see it any other way (exception is IMAX where the 3D actually works). An annoying number of films are now being released 3D only. With kids' films there's always a 2D version as you're not supposed to expose under-5's to possible eye-strain.
The forthcoming Judge Dredd film is being filmed in 3D. I asked their publicists if there will be a 2D version and the reply I got was "Well, it's being filmed in 3D so I don't know how they'd manage that". Erm... TV trailers featuring scenes from the film will be in 2D as will DVD, Blu-Ray and later TV releases. I'm fairly sure it's possible.
Most cinemas charge £1.50 for a pair of 3D glasses. Buy two of those, making a total of £3; pop the left lens out of one frame and the right lens out of the other, swap them over and pop them back in, and you have two pairs of 2D glasses for 30 seconds'-worth of effort and around half the price of a single pair purchased from this guy....
I'm not sure that'd work? The lenses are polarised in two different directions (left vertical,right horizontal or somesuch setup).
So you have two pairs of glasses:-
V - H and V - H
swap the left lense on the first pair with the left lens of the second pair - what have you got?
V - H and V - H
Or have I just blundered into the obvious trap of replying to this?
posted then realised - you mean PHYSICALLY turn the lenses around first and then put a left in a right and a right in the left - that works if the glasses have circular lenses - if they don't they won't fit/leave gaps? Are the lenses in these glasses symetrical?
Only been to one 3D Film (Toy Story 3) it was crap, wasn't paying much attention to the things on my face.
Real3D uses left and right circular polarised filters. Older tech used horizontal and vertical plane polarised filters which were reputed to give more eye strain than circular polarisation. So as long as you take RC-LC and RC-LC make a pair of RC-RC and LC-LC or H-V and H-V to make H-H and V-V depending on cinema (IMAX Waterloo showed Avatar in H-V when I saw it) you will be able to enjoy your over priced 3D in 2D.
My kids have autism and the family is active in the local Autistic Society. A fair number of the children can't cope with 3D movies but some others can. I was about to make a pair of these glasses for someone to try and fix the problem that one of their kids wants to see 3D and the other doesn't. Their whole family will be able to go and see the same film.
I agree it's not for everyone but this does solve a real problem we have.
if I started making lots of these when I made some for my other half. (she managed about 3/4Hr of Avatar before watching the rest in bleard 2D)
Paris, my other half looked just like her while peering over the 3D specs... honest. (well OK she is red head with much bigger boobs)
are _circularly_ polarised. It means you can roll your head about without losing the stereo effect (try it with linear polarised glasses- it screws up much worse than in the cinema).
You can also see the effect if you look at an LCD monitor with them- the linear polarised glasses have a totally different effect to the circular polarised ones.
Every 3D film I've seen so far has been crap. I don't mean the 3D was crap, I mean the content of the film is crap. It's pretty standard Hollywood practice, when there's some new bandwaggon like the current trend for 3D they will push any old crap on that bandwaggon hoping that the bandwaggon alone will sell the movie. Unfortunately for those who have faith in human nature it seems that Hollywood is usually right.
