When the Canon SLR camera is overexposed, we can reduce the aperture, speed up the shutter, lower the iso, or choose a suitable metering point, which can avoid overexposure. How to operate specifically depends on the shooting environment at that time.
For novices, it is really difficult to use the M stop to achieve correct exposure.
When practicing, you can use the automatic ISO function as an aid. The automatic ISO function allows the camera to adjust the sensitivity within a certain range as needed; you only need to set the minimum shutter speed and maximum sensitivity.
