Jp 7. 接写、複写撮影

接写、複写撮影の際は特にカメラブレに注意してください。カメラブレ を防ぐ方法として、しっかりとした三脚を用い、ケーブルレリーズ、ま たはリモートコードを併用することをおすすめします。接写撮影では、 一般に被写界深度が著しく浅くなるので、奥行きのある被写体の撮影で は、絞りを十分絞って、露出時間を長くしてください。また、写したい 部分をフィルム面(撮像素子面)と平行に置くことなどの注意も必要です。

クローズアップレンズをお使いの場合は、マニュアルフォーカスで撮 影してください。

8.露出倍数について

レンズの F 値は無限遠での被写体の像の明るさを表しますが、撮影倍率 を上げて撮影すると像の明るさは F 値より減少します。このときの実質 的な明るさを有効F値(実効 F 値ともいいます)と呼び、実質的な明る さが減少した分だけ増やす露出の係数を露出倍数といいます。

9.有効 F 値の変化について(P.146 の図参照)

このレンズは、撮影倍率が上がるに従いフィルム面上(撮像素子面)で の像の明るさは減少します。有効 F 値(実効 F 値ともいいます)は大き く(=暗く)なります。この変化量はカメラが自動的に補正するので、 露出を決める際や TTL 調光によるフラッシュ撮影で露出倍数を考慮する 必要はありません。

なお、カメラ側の外部表示パネルやファインダー内表示部で表示される 絞り値は露出倍数が自動的に補正された F 値です。
