1:1 Macro and Beyond
大於一比一放大倍率微距攝影
Hello friends, today I'd like to share some photos I took of a Trogonoptera brookiana specimen. I explored the details on the wings at 1x magnification and some at roughly 5.55x magnification. I recommend clicking on the images to view them in full-size!
Also please feel free to use the #SciencePic tag for science related photos!
大家好，今天我來分享一些翠葉紅頸鳳蝶標本的照片。我透過1倍及5.55倍放大倍率來拍攝翅膀的細節，因此我建議點開全圖來觀賞！
順便來推廣一下 #SciencePic ！
Shots at 1x magnification / 1倍放大
These shots are roughly at 1x magnification, I used a Canon EF 100mm f/2.8 macro lens adapted on a Sony A7 mounted on a macro focusing slider attached to a tripod. Light source was a table lamp.
這些照片大約是一倍的放大倍率，我用了Canon EF 100mm f/2.8 微距鏡轉接到Sony A7機身，固定在微距雲臺及脚架上。光源來自一盞燈。
Shots at 5.55x magnification / 5.55倍放大
These shots are roughly at 5.55x magnification, to achieve this I attached a Canon EF-S 18-55mm lens in reverse to the 100mm lens. With the 100mm lens focused to infinity, the 18-55mm in reverse acts like a magnifying glass. The total magnification is calculated by 100 divided by the focal length of the reversed lens, in this case I used 18mm, so I can get the maximum magnification out of this setup. The 100mm lens is kept at its maximum aperture of f/2.8.
這些照片大約是5.55倍的放大倍率，透過反裝在100mm鏡頭前面的Canon EF-S 18-55mm鏡頭來實現。此組合裏頭的18-55mm扮演的角色就像一個放大鏡，而100mm鏡頭則像顯微鏡的管鏡。我將18-55mm鏡頭設在18mm段，放大倍率是100除以18等於5.55。100mm鏡頭光圈拍攝時全開在f/2.8。
