Sony a7m4 night time-lapse photography tutorial

Answer 1

The following is a tutorial for the SonyA7M4 night time-lapse photography:

** 1. Selection of exposure mode **
1. **M (Manual Mode)**
- [** Pros **: Able to precisely control the exposure parameters to avoid problems that may occur when the light changes rapidly during the day and night.] However, it should be noted that when the day turns to night, the light changes rapidly. Manual adjustment of the shutter speed may not be as fast and smooth as the A file, but with the help of the Monitor + mobile APP, the exposure parameters can be better controlled.
- ** Setting **: Set the camera to M mode and set it to the USB.
2. ** A-grade (Aperture priority)**
- ** Note **: When using the A file, the exposure time may change when the moon appears, such as 1/5, 1/8, 1/10 seconds, etc. To ensure that the moon remained in the 1/4 second state, he needed to add an RV. In addition, although the A7M4 had the Ael button to lock the exposure, this button was ineffective during the delay. It was necessary to terminate the delay and press the Ael button and then quickly restart the delay. This would cause at least a one-second interruption in the shooting, and it would cause shaking if the camera was not controlled by the phone.

** 2. Setting the parameters **
1. ** Anti-shake **: It is recommended to turn off anti-shake and set SteadyShot to off.
2. ** USB **: The original sensitivity is 100 - 51200, which can be expanded to 50 - 204800. It can be set according to the actual lighting situation. For example, in a dark night scene, the USB should be increased appropriately. However, you must pay attention to the noise that may be caused by the high USB.
3. ** Shutter Speed **: If you use the M gear, set the shutter speed according to the night light and the desired effect. For example, you can start with a slower speed (if it takes a few seconds or longer, you need to use it with a tripod). If it's A, pay attention to the impact of the moon on the exposure time and make corresponding adjustments.
4. ** Aperture **: adjust the aperture size according to the depth of field and the amount of light. A large aperture (low F-value) could increase the amount of light entering and obtain a shallow depth of field effect, while a small aperture (high F-value) was the opposite.
5. ** Other settings **
- Before shooting, it is recommended to check the parameters in the different settings of static and dynamic. This way, you can get more custom operations when taking photos and videos, and it is convenient to quickly switch between taking photos and shooting videos. The specific way to open it was to go to "Mentor","Setting","Operation","Different settings for static and dynamic. After opening it, check all the options inside and confirm to save it.

** 3. Filming preparation **
1. ** Focus **: Because it is a night shot, the dim light may affect the autofocus effect. You can focus on a bright spot first, then switch to manual focus mode to lock the focus, or use the camera's live view function to enlarge the picture for manual precision focus.
2. ** Tripod **: Night scenes usually require a long exposure time, so a tripod must be used to keep the camera stable and avoid blurring the image due to camera shake.

** 4. Save custom shooting parameters (option)**
Because the A7M4 could save the shooting parameters as the numbers 1, 2, and 3 on the custom dial, if you often shoot night scenes with delay, you could set a set of special night scene delay shooting parameters and save them to the custom dial, and the next time you shoot, you could directly turn the corresponding number to refocus.
