3d glasses

[lgongtsyn]

hi guys,

I am trying to find some 3d glasses, I was wondering if you guys could tell me where I can find it in Hong Kong.

The 3d glasses are those paper ones with red and blue tinted on each side.

your help is much appreciated!!

cheers

3D film 裡面會用的, 主要有三種: Two-color anaglyph, linearly polarized glasses, circularly polarized glasses

p.s. LCD crystal glasses 用系 CRT mon, 所以我唔計

Two-color anaglyph 系最舊既技術, 顏色又唔清, 正確黎講系用 red-cyan filter glasses, "Spy Kids 3D:Game Over" 同埋 "咒樂園" 都有用呢種效果, DVD 亦都送埋副鏡, 呢兩部戲都系 2003年出既

thx for your reply, but i think I am looking for those very low end ones....those paper ones??

I am trying to create those Anaglyph Images in after effects...to give you an example:

你只系想買副鏡... 上網可以買, 不過加埋運費可能同買我介紹既 vcd 價錢差不多, $40 以內 (之前講漏左 vcd 都送 3d glasses 添)

To lgongtsyn:
Perhaps the easiest & cheapest way to get one is to
make your own pair of red-cyna filter glasses with
colored transparency. But the result may not be as good
as the actual ones.

I did some searching around the Web. Looks like it's much
easier for you to get free sample one (I don't know how many
pairs you needed) from overseas than from HK.

help is much appreciated!

你影既 object 太近喇, 同埋冇一個 overlap 位俾對眼做 focus, 咁樣會睇得好辛苦, 而且你個 red-cyan 好似 reverse 左喎

我都 post 一張俾你睇下, 用 photoshop 做, 夜嗎嗎只可以去門口樓梯位影, 距離我最近既 object 有6-7尺, 正常一帶眼鏡就即刻 focus 到

路過ing!

水兄這一幅, 我見過來說, 最好的一幅! 可能本身是一點透視的關系！

The 3d glasses are those paper ones with red and blue tinted on each side.

Two-color anaglyph 系最舊既技術, 顏色又唔清, 正確黎講系用 red-cyan filter glasses,

小發現! blue 不等於 cyan!
清楚d講: 正解是cyan，因為cyan是 red 的對比色！
光學上，可見光經過 red filter，會過濾了cyan 光線，從而看到純紅的景物。

可見光 = (red + cyan) // 可見光等於 red 加 cyan。
　└─────┐
red filter = 可見光 - cyan
red filter = (red + cyan) - cyan // 代入。
red filter = red

另外:blue = cyan - green

單機影的話, 最緊要移動時要定, 高低唔准可以 photoshop 執. 左右 image 重疊位置最好就系你既 focus 位置, 即系 photo 既重點位, 呢個 trick 系引渡你雙眼既焦點位


p.s. 我都有成6,7年冇整 anaglyph images, 以前 phtoshop RGB channels 唔可以好直接個別 move (ps6 之前既 ver), 依家 cs/ cs2 可以喇
