立體電影破壞電影幻覺！

正當DreamWorks或是Disney、甚至大導演James Cameron都跳上3D立體電影的馬車時，有些人反倒認為立體電影只會破壞電影的幻覺，對說故事只有反效果，美國知名影評Roger Ebert在這篇文章：D-minus for 3-D中，說明他的看法：

"...Every time that happens, it creates a fatal break in the illusion of the film. The idea of a movie, even an animated one, is to convince us, halfway at least, that that we're seeing on the screen is sort of really happening. Images leaping off the screen destroy that illusion."

立體電影放映之中，物體朝觀眾飛來的時候，電影製造出來的幻覺常常因此被打斷，電影的目的是要人們相信銀幕上的畫面是真實的，不過這樣的立體效果卻打斷了這種幻覺。

"There is a mistaken belief that 3-D is "realistic." Not at all. In real life we perceive in three dimensions, yes, but we do not perceive parts of our vision dislodging themselves from the rest and leaping at us."

許多人錯誤地認為3-D立體效果是"寫實的"，事實上一點都不，真實生活中我們看到的景象是立體的沒錯，但是我們不會看到物體脫離背景跳向我們，一部分原因可能是因為立體效果並非"完全"立體，比較像是由許多不同深度的平面層次組合而成，前景人物或是飛向觀眾的物件因此看起來像是跟背景脫離。

"Ask yourself this question: Have you ever watched a 2-D movie and wished it were in 3-D? Remember that boulder rolling behind Indiana Jones in "Raiders of the Lost Ark?" Better in 3-D? No, it would have been worse."

Ebert問，你可以問問自己，你會希望哪部平面的電影是立體電影呢？法櫃奇兵中巨石滾落的那個鏡頭，你會希望它有立體效果嗎？如果它有立體效果的話，會因此比較好嗎？並不會，而且它有可能會更糟，Ebert也舉了最近幾個他看過的立體電影，他反而希望他們是一般平面電影，而且覺得他們如果是一般影片的話，搞不好他會喜歡這些影片，其中一個例子是Journey to the Center of the Earth。
"I have witnessed a believable 3-D illusion. It was at a ShoWest demonstration of Douglas Trumbell's doomed Showscan. He projected 70mm film at 60fps. It created the illusion of depth not by leaving the screen but by seeming to recede within it. It was like looking through a window and seeing the perspective of reality."

Roger Ebert曾經在ShoWest看過真正的3-D立體幻覺，影片是70mm每秒60格的投影，所產生的深度幻覺是往內凹，而非向前凸的，你真正感覺像是透過一扇窗戶觀賞真實的景象，不過這樣的技術成本過於高昂，難以普及。
