What must be increased when using a filter?

ISO setting
Shutter speed
Exposure
Contrast

The correct answer is: Exposure

When using a filter, especially in situations where the filter reduces the amount of light entering the lens, it is necessary to increase the exposure to compensate for this reduction. Filters, such as neutral density filters, are specifically designed to decrease the intensity of light hitting the camera sensor. This means that without adjusting for the light loss, your images would likely come out underexposed, appearing too dark. Increasing the exposure can be achieved by adjusting various settings, such as using a longer shutter speed, widening the aperture, or increasing the ISO setting. However, these adjustments are all aimed at ensuring the right amount of light reaches the sensor, ultimately leading to properly exposed images. Increasing exposure can involve multiple techniques, but the primary focus when using a filter is to ensure that the overall image brightness remains balanced. Other options may involve different aspects of photography but do not directly address the requirement to compensate for light loss caused by the use of filters.
