Nikon D5500 photography problem, please ask the master for answers

Hello, sir, it seems that you have just started taking photos.

The situation you are talking about is not a crash but a shutter speed that is too slow

In a situation where the light is relatively dark. If the shutter speed will become slower, you can increase the aperture or increase the ISO sensitivity (the ISO is too high, the photos will have more noise)

Your shooting environment is too dark. In this case, you don’t need a tripod. Can’t take a photo

I hope it will be adopted
