Adjusting the camera shutter
The camera with intermediate mirror closure can be set at any speed. While the camera with slot closure can only adjust the speed profile of X (usually 1/60s). Or you can adjust your speed according to your instructions.
How to use:
1. Determine the distance between the camera and the main feature with your eye, and then find that distance on the top of the exposure meter.
2. Find your camera’s photonastia using the first vertical line to the left of the exposure sensor. The connection of these two lines is approximately equal to the number of openings.
3, Can you get your opening number from the following formula?
Index (GN) = aperture (F) × Distance (L)
For example, Photonasty is ISO100/DIN21, the distance between the camera and the main feature is 5m, then the aperture is about F/4
Suitable for all standard digital cameras (e.g. 602.717.750, G3, etc.) and conventional cameras. Except for Minolta and Sony anti-intercalation shoes. Even if there is no flash shoe, the primer flash can also be used successfully.
