Excuse me, how does a SLR shoot this luminous object?

This contrast scene (the luminous point is very bright, others are too dark) can be exposed by surround exposure.

Don't type, copy Baidu content as follows:

Surround Exposure Exposure Surrounding is to form three or five photos with different exposures by means of middle exposure value, reducing exposure value and increasing exposure value after one shot. Its function is that among these photos with different exposures, there can be photos with exposure close to the photographer's needs. In addition, HDR photos can also be synthesized later.

Surrounding exposure (also called bracket exposure) can solve this problem well. The method is to expose a photo according to the luminosity value, and then increase and decrease the exposure on this basis. If you are still not sure, you can change your exposure and take more photos. The exposure can be adjusted according to the level difference of 1/3EV, 0.5EV, 1EV, etc. The exposure of each photo is different. You can choose a satisfactory one from a series of photos. The automatic exposure function on digital cameras even allows users to combine underexposed and overexposed photos into a precise exposure photo-even if you don't have any photos accurately exposed when shooting.
