How to take photos in caves?

Cave photography needs preparation in advance. It is best to choose a SLR camera with built-in metering. The bigger the aperture, the better. It is best to use a wide-angle zoom lens. A flashlight should be prepared to provide illumination for the operation.

Generally, there are lights in the cave. When taking pictures, you should pay attention to avoid direct light to the lens and use a hood.

Cave photography should use flash. If conditions permit, you can prepare several more, equipped with synchronous sensors. Generally, the humidity in the cave is high, and the temperature difference between inside and outside the cave is obvious, so the camera often casts a layer of water vapor on the lens after entering the cave. The prevention method is to use the camera before entering the hole, and then take it out 30 minutes after entering the hole.
