Exposure Compensation Limit

On the Canon EOS 1500D, exposure compensation in Shutter Priority mode may appear ineffective because the camera automatically adjusts aperture to maintain correct exposure. If the lens reaches its aperture limits, compensation has no visible effect.

ISO Settings: If ISO is fixed, the camera has fewer options to adjust exposure. In Auto ISO, the camera may override compensation by adjusting ISO instead.

How to Make Exposure Compensation Work

- Use Aperture Priority (Av) or Program (P) Mode: These modes give the camera more flexibility to adjust shutter speed or aperture, so compensation is more effective.

- Enable Auto ISO: This allows the camera to adjust ISO when aperture limits are reached, making compensation visible. (咁點解唔自己調 ISO?)
