Maybe you have seen such a scene in a professional photography agency or studio: the photographer shoots in the studio (indoor portrait and still life photographers are most commonly used), and the other end of his camera is connected to the computer with a USB cable, and the camera beside him People can view the photos in the photographer's camera in real-time on the computer. Instead of having to look around the photographer's camera screen as before.
Online shooting is a very convenient function. In addition to allowing multiple people to view photos in real time (customers can view photos at any time, which is particularly important during commercial shooting), photographers can also view the details of photos on the big screen and make timely decisions during shooting. Adjustment, if you are in a hurry, the retoucher can also synchronize post-processing.
This is not only a function of high-end SLRs, ordinary cameras can also be connected to a video output terminal cable to play back photos on a computer or TV.
When browsing photos at ordinary times, some people may like to filter pictures while looking at them. If they are a little faster, the tragedy of accidental deletion may occur.
In order to avoid this from happening, you can select single or multiple photos in the "Protect Image" function of the camera, and mark these photos as protected (there will be a small key icon on the photo information at this time), so that you can Protect important images from accidental deletion.
It should be noted that this function is only valid for the "delete" operation. If you choose to format the memory card, even if you protect the image first, the image will still be deleted by the formatting operation. This needs special attention.
