How to set the shutter speed of ten-stage reducer

15 steps and suggestions for using a reducing mirror (nd)

1.

Set the minimum allowable sensitivity of the camera (generally ISO 100). Low-sensitivity shooting can make the picture more delicate, while high-sensitivity shooting will reduce the picture quality and cause noise. When shooting with a reducing mirror, it is necessary to reduce the sensitivity value and extend the exposure time to complete the shooting.

2.

Install the cable release. Because of the long exposure time when using the subtracter, it is necessary to install a cable releaser to shoot and use a remote controller to control the shutter to reduce camera shake and damage the picture. For convenience, try to choose a cable release that can set the end time.

3.

Shoot with a tripod. Similarly, due to the long exposure time using the subtracter, a tripod must be used to ensure the picture is clear. Before using a tripod, you can take a picture with your hand and roughly determine the composition, then set up a tripod and adjust the composition.

4.

Set the exposure mode to manual (M file). After the camera is fixed, the exposure mode needs to be adjusted to manual because the shutter and aperture parameters need to be set by themselves.

Step 1: In AV mode, do composition, focus, measure light, record shutter speed, and adjust the focus button from AF to MF (focus lock);

Step 2, add a reducing mirror, switch to manual mode (M-range) and reset the parameters. Of course, the sensitivity and aperture should be the same as those in AV mode just now, and the key is to set the shutter speed. About adding
