There is a time and a place for everything–even on-camera flash!
When I am working as an event photographer, I often have to use an on-camera flash.
In rare opportunities, I have an assistant helping with off-camera flash. When I have to use flash to improve the available light then, this is my first preference when doing event photography.
The Step-and-Repeat, also known as the Red-Carpet photos, are set up in places where you cannot set up lights. People are moving around so much that the odds of someone bumping into a light stand are too risky.
Sometimes I compete with sunlight and use the on-camera flash to overpower the sun if possible. This is where I will underexpose the photo by 1-stop and overexpose the flash by 1-stop, giving me a well-exposed picture.
As you can see in some of these different situations, there was no setting to photograph all the moments. Your Smartphone Camera cannot capture all of these even with the built-in light on the phone.
Professional event and meeting planners know that a Smartphone isn’t reliable for capturing their events. They hire professional photographers to cover their events. They need someone with experience to know how to get the best photos in any situation.
