As a complete noob to photography, I'm struggling to understand what the 'Backlight Compensation' button is for on my Canon AV-1 and under what circumstances I should/would use this setting? I can only find technical explanations, but am having a hard time translating this into real world, simplified, example and how a photo will be impacted with or without using the setting.
I'm also wondering if this feature works when the camera shutter mode is set to
A (Automatic) since the AV-1 is aperture priority. Since this camera automates the shutter speed based on the selected ISO & Aperture, it's not immediately clear to me if the backlight compensation button only works when using another a different shutter mode such as Bulb or Flash 60.
The Backlight Compensation button, when pressed, will automatically reduce the shutter speed by 1 1/2 steps to increase exposure
