These take-off shots are even more challenging because they require a wide-angle lens, which means he must be less than 2cm from the butterfly.
这些起飞镜头更具挑战性，因为它们需要用广角镜头，这意味着他必须离蝴蝶不到2厘米。
That makes it sound easy, and artificial, but Peters insists it is still a massive challenge. He typically takes between 10,000 and 20,000 shots to get one butterfly take-off sequence in focus. At such high shutter speeds, the depth of field is tiny, and as butterflies do not fly in a straight line they swiftly flutter out of focus. As well as thousands of attempts, it takes patience and fieldcraft to anticipate a butterfly’s likely flight-line — and catch it — in focus.
这听起来既简单又人为，但彼得斯坚称这仍是一项巨大的挑战。他通常要拍一万到两万张照片，才能得到一组对焦清晰的蝴蝶起飞序列。在如此高的快门速度下，景深非常小，而且蝴蝶并不沿直线飞行，很快就会扑腾着飞出焦点。除了成千上万次的尝试，还需要耐心和野外经验来预判蝴蝶可能的飞行路线——并在焦点内捕捉到它。

Throughout the trip, Jackson juggled multiple cameras and plate sizes using the “collodion process” that required him to coat the plates with a chemical mixture, then expose them and develop the resulting images with a portable darkroom. The crude technique required educated guesses on exposure times, and involved heavy, awkward equipment — several men had to assist in its transportation. Despite these challenges, Jackson captured dozens of striking photos, ranging from majestic images like his now-famous snapshot of Old Faithful, to casual portraits of expedition members at the camp. While veterans of previous expeditions wrote at length about stunning trail sights, these vivid photographs were another thing entirely.
在整个旅途中，杰克逊使用“火棉胶工艺”同时摆弄多台相机和多种尺寸的底片，这种工艺要求他先给底片涂上一层化学混合物，然后曝光，再用便携式暗室冲洗出影像。这种简陋的技术需要凭经验推测曝光时间，而且所用设备笨重难使——需要好几个人协助搬运。尽管困难重重，杰克逊还是拍下了几十张引人注目的照片，从他那张如今已闻名于世的老忠实泉快照这样的壮丽画面，到营地里考察队员的随意肖像，不一而足。以往考察的老手们曾长篇累牍地描写沿途的壮丽景色，而这些生动的照片则完全是另一回事。
