Try to choose two identical cameras for two-station shooting of extended data, and debug the two cameras before shooting, so that the aperture, filter and recording format selected by the two cameras are the same.
Precautions for shooting with dual cameras:
Communicate with customers before shooting, understand each link of the activity and design each link well.
Photographers communicate with each other, and photographers study and design all links and work together. Photographers should study and design all aspects of the whole activity according to what they have learned from customers, and make clear their respective division of labor.
For example, in the wedding video, when the groom arrives at the bride's house, it is customary to call the door. If there is a table for two at this time, one can record the groom's situation outside, and the other can record the bride's relatives and friends asking about the groom or bride inside.
