What is the effect of increasing the ISO setting on your camera during nighttime photography?

Increasing the ISO setting on your camera during nighttime photography enhances the sensor's sensitivity to light, allowing it to capture images more effectively in low-light conditions. This adjustment results in an increase in exposure, meaning that the camera can register more light per unit of time, which is especially beneficial during nighttime shoots when there is less available light.

By selecting a higher ISO, you make it possible to achieve a well-exposed image without needing to significantly alter your aperture or shutter speed, thus balancing the light intake for a clearer and brighter photograph. However, it's important to note that increasing the ISO can also introduce noise into the image, which is the grainy or speckled look you may observe, particularly at very high ISO levels. This effect is crucial to consider in order to maintain image quality while optimizing for low-light conditions.

In contrast, options that refer to decreased noise, faster shutter speed, or wider depth of field do not accurately represent the impact of increasing ISO, as these attributes do not directly correspond to changes in ISO settings.
