スマートフォンのカメラで撮影すると写真のサイズが大き過ぎて、扱いに困ったことはありませんか? また、工事用のデジタルカメラでピントや露出調整が思うようにできず、あとで大事な写真が使えなかったという経験はありませんか? そのような方にとって、このアプリを使うメリットはたくさんあります: - 工事用カメラ(CALSモード搭載カメラ)と同じ1280X960サイズの写真を撮影でき、ファイルサイズは500KB程度以下に抑えられます。 - 撮影直後に、いま保存された画像が表示されます(表示時間を1秒から設定可能)。ピンチやダブルタップ操作で拡大し、細部まで確認することができるので、ピンボケなどの撮り損じを防ぐことができます。 - 撮影時に画面タップすることで、直感的にフォーカス、露出(明るさ)、ズームの調整ができます。 - 矢印ポインターを撮影画像に重ねて表示し、注目点を指し示したい場合に、ポインター付きの写真として保存できます。ポインターは好きな位置に移動させることができます。また大小2種類のサイズに切り替えられます。 - ボリュームボタンだけでシャッター操作と画面遷移が行えるので、手袋をしたまま撮影ができます。 - 撮影日時や撮影情報、位置情報などをEXIF形式で写真に埋め込むので、電子納品を含め様々に活用していただけます。 - 位置情報を保存するかどうかを撮影画面でON/OFFできるので、不用意に個人情報を拡散させてしまうリスクが軽減します。
