真實(shí)的視覺(jué)錯(cuò)位The pictures that make you look twice: Intriguing optical illusions that were created with no camera trickery真實(shí)的視覺(jué)錯(cuò)位With cameras often believed to reflect the real state of things, to create a facsimile of the true state of the world, when photographs show something wildly chimerical it delights the imagination.相機(jī)通常是用來(lái)反映事物的真實(shí)狀態(tài)的，是對(duì)世界真實(shí)狀態(tài)的復(fù)制，可是當(dāng)相機(jī)捕捉到了一些荒誕不經(jīng)的圖像時(shí)，它也愉悅了我們的想象力。Many of the incredible images in this set play with our sense of perspective by bringing side by side two elements that are, in fact, distant from each other in depth.這組圖片通過(guò)把兩種完全不同的元素組合在一起從而創(chuàng)造了視覺(jué)上的假象，讓我們信以為真。That illusion leads to such remarkable images as the festival-goer who appears to be projectile vomiting a rainbow, the ant that seems to be facing off with a helicopter at dusk, and the girl who looks as though she is wearing a tulip for a skirt.這些視覺(jué)上的假象給我們形成了如此非凡的影像，包括節(jié)日狂歡者噴射性地吐出彩虹，在黃昏時(shí)刻一只螞蟻好像在和一架直升機(jī)在對(duì)抗，以及有一名女孩子正在把一朵郁金香當(dāng)成裙子在穿著Such images are possible to create for yourself, but they require carefully executed photographic techniques to capture the required depth of field to keep each element in focus, despite the differences in distance.你自己也可能能夠拍攝出這樣的照片，但是這需要精巧的攝影技術(shù)來(lái)捕捉一定的視野深度來(lái)達(dá)到畫(huà)面中元素清晰的目的，在元素在距離上存在差異的情況下。Smaller apertures, shorter focal lengths and further focusing distances produce deeper depths of field, so to create an image where the background is as sharp as the foreground you will want to use a wide-angle lens set to the highest F-stop number available, and stand back a little from the subject.更小的孔徑，更短的焦距以及更進(jìn)一步的聚焦距離才能生出更深的野深度效果，為了拍出一張背景與近景效果都一樣強(qiáng)烈的圖片，你可能會(huì)使用調(diào)到最高F光圈的廣角鏡頭，并且以向后退一點(diǎn)的距離來(lái)拍攝物體。This will capture the image with a hyperfocal distance, bringing all objects into focus. The finished image will be sharp from front to back.這樣就可以以超焦距來(lái)拍攝物體了，畫(huà)面中所有的物體都可以非常的清晰了。拍完照后，整張照片從前到后視覺(jué)效果都會(huì)非常的強(qiáng)烈。If you have a pocket camera, setting it to landscape mode should work almost as well.如果你擁有一個(gè)袖珍照相機(jī)的話，那么把其設(shè)置成橫向模式也可以起到相同的效果。But when it co
