ビデオの撮影で使いたいので、シャッタースピード固定でF値が変化して行く方が使いやすいんだけどな… ビデオなので厳密な数値を得るというより照明を当てた時に明るさにムラが無いか確認するのに使いたいから、シャッタースピードが変わって行くのは使いにくいです。 有償なので、アップデートに期待します！

Description
This app will turn iPhone into exposure meter for cameras.
It can continuously measure exposure value and indicate the information without releasing the shutter.
It allows you to recalculate and indicate the shutter speed together with other ISO values and F values even during the measurement.
The measurement is interrupted by the save button, and then write a row exposure value which iPhone automatically set into the image that iPhone had been taking,
The image with the row exposure value is saved as a sample and displayed.
You can see the saved images on a list of images in the history window.
You can adjust and rock the exposure on the tapped point of the preview screen.
The exposure rock can be cancelled by the Auto button.
The shutter sound can be reduced by the volume button. However, it becomes the normal volume if it is set mute.
At first the app puts high priority on ISO and F in exposure calculation.
Under the exposure measurement, it indicates variable aperture stops (F-number) at a fixed shutter speed when you manually change the shutter speeds.
Or, when you manually change the aperture stops (F-numbers), it indicates variable shutter speeds at a fixed aperture stop.
If you change the ISO value, shutter speed or F-value changes depending on the mode at the time.
The range of ISO vales, F values and shutter speeds are as follows. (In the new version, detail display mode is added in which F,ISO,SS values are changed by 1/3 step)
ISO vales:
"25","50","100","200","400","800","1600","3200","6400","12800","25600","51200"
F values:
"F0.7", "F1", "F1.4", "F2", "F2.8","F4", "F5.6", "F8", "F11", "F16","F22", "F32"
shutter speeds:
"60","30","15","8","4","2","1","1/2","1/4","1/8","1/15","1/30","1/60","1/125","1/250","1/500","1/1000","1/2000","1/4000","1/8000"

How to use:
(1) Immediately after start-up, this application starts the exposure calculation automatically and it displays the values of ISO, F and SS in the wheel.
(2) Exposure is recalculated in accordance with the subject that is reflected in the camera, the value of the SS will change accordingly. When you point the camera toward bright, the value of SS is reduced. Turning the camera to darker, the value of the SS will increase.
(3) If you change the value of the ISO in the wheel, the value of the SS will change accordingly. Changing the value of F in the same manner, the value of the SS will change. Further, changing the value of the SS, the value of F will change.
(4) If you tap the "Save" button, the exposure value displayed at that time is locked and a photo is taken. A reference exposure value that iPhone camera set to itself is written in the photo. (The reference value is different from that displayed in the wheel. It is not possible to set exposure value in the wheel to iPhone camera itself.)
(5) If you tap the "measure" button, it restarts the exposure calculation and re-displays the values of ISO, F and SS.
(6) If you tap the "History" button, the History window appears and the contents saved are listed. They are save date and time , photos and the exposure values you had set by the wheel when you save.
(7) You can enlarge the photo by tapping it.
(8) It changes to delete mode when you tap the "trash", delete mark appears in the photo that you tap. If you tap "Done", photos marked for deletion will be deleted.

F値が可変するといいんだけどな
アップデートが充実しています。
写真を撮りながらというよりは、カメラを持つ前に自分の勘を確認するために使っています。 購入時は使いやすいとは言えませんでしたが、数回のアップデートで見違えるようになりました。今後も期待します。 多くのアンドロイドアプリと違い、カメラ側から情報が入るので画面での直感的操作が可能です。 特にF値をもう少し細かく割り振ってもらえると助かります。
