The starry sky on Earth is so beautiful, why are those photos taken on the moon

It’s not that you can’t see the stars on the moon, it’s that you can’t see the stars in the photo. Because of the limited latitude of film, although there are no atmospheric stars on the moon that are brighter than those on Earth, they are still insignificant compared to the brightness of the moon itself. Therefore, under the premise of accurate exposure of the moon, stars cannot be photographed.

Latitude: Latitude refers to the film's ability to express the entire brightness range of the subject. Generally speaking, the latitude of film is limited and is smaller than the real scene. Therefore, when shooting, we often encounter situations where the contrast of the scenery is too large. At this time, we must choose a range, a range that needs to be expressed with film. Suppose there are 200 levels of scenery from darkest to brightest, and the film can only express 100 levels. If you choose 1 to 100, then those scenes between 100 and 200 will only have one side white on the film, that is, the It's lost its level. This is one of them, and another point is that although color film has a large tolerance, it can express the gradation most accurately, and the range of colors is very small. This is why accurate exposure is required. If it is half a stop, the effect will be It will be different.
