What embarrassing things have you encountered in your photography work?

I think I have encountered many embarrassing things in my photography work. Let me tell you a few simple things, such as:

There is no memory card inserted in the camera: this is an embarrassment shortly after entering the SLR camera. Once I went out to shoot, I took dozens of pictures and found that the camera was not inserted with a memory card. Embarrassed, every photo can be previewed on the display screen after shooting, but it only appears in "demonstration mode", and I didn't know about the camera at that time, and I didn't know that the photo was actually saved. Why is this happening? The main reason is that I didn't read the instructions.

Shooting with iso6400 value in broad daylight: This is another embarrassment caused by camera setting problems. On the first night of shooting, I talked nonsense in the camera setting menu and tried to operate the camera. One of the iso settings is that the automatic iso sensitivity control is set to ON. After ON, two sub-items: maximum sensitivity and minimum shutter speed are activated. After activation, ISO sensitivity, maximum sensitivity and minimum shutter speed all have corresponding values to be set. The next day, I took many photos in this way, but I couldn't find them. It's really awkward with capitalization.

Deleting photos by mistake: once, when importing photos into the computer, the method of "cutting" was adopted, but during the operation, the computer somehow failed to save them, but there were no photos on the memory card. Usually when cutting and pasting, the cut file is still there without pasting, but this time it is inexplicably lost. Because photos are very important, I later found a "retrieval software" on the Internet to get it back. However, it should be noted that if the files are too large and there are many files, the recovery time will be longer. These are the things that I feel embarrassed when I am engaged in photography. The above is purely a personal opinion.
