焦点合成 Focus stacking [Composite photograph]
奥行きのある被写体の近接撮影ではレンズの絞りをF8にしても、全部にピントが合わない。F11以上に絞るとレンズの回析現象で解像度が低下する恐れがある。デジタル写真では、焦点位置を変えた複数の写真から焦点合成により擬似的にピントが合った写真を作ることができる。下の写真の焦点合成にはCombineZPを用いた。
In the close-up of the subject with depth, even squeeze the lens aperture to F8, not to focus on all of them. In aperture F11 or more, there is a fear that the resolution is reduced by a diffraction phenomenon of the lens. In digital photography, using plurality photographs with different focal positions, it is possible to make a picture of the pseudo pan-focus by the focus stacking. I was using a CombineZP to focus stacking the photo below.
通常の撮影 60mmレンズ、F8
Normal shooting 60mm lens, F8
ピント位置を少しずつずらした8枚の写真を焦点合成
Focus stacking using 8 photos shifted focus position gradually
