How do photos with long exposure not get brighter.

540 views

I’m not a photographer but I have some basic knowledge of some terms. For example, when you take a longer exposure of a photo It should allow more light to enter the lense. Wouldn’t that make everything completely overly bright. However, I see many photos that look like time is just stretched like taking a time lapse. How does this work?

In addition to the methods others have said, there is something called a neutral density filter, which attaches to the front of the lens and blocks a certain percentage of all the light coming in. (Basically sunglasses for the camera.)

A friend of mine used two strong ones to take ~30 second exposures in the middle of the day for a project he did.
