A strobe and an on-camera flash are both used to produce a burst of light for photography. However, there are some key differences between the two:nnPlacement: An on-camera flash is mounted on the camera, usually on the hot shoe, whereas a strobe is a separate, standalone unit that can be placed anywhere in the scene.nPower: Strobes are typically more powerful than on-camera flashes, allowing them to illuminate larger areas or subjects from greater distances.nModifiers: Strobes often have interchangeable modifiers, such as reflectors or softboxes, that allow the photographer to shape and control the light output. On-camera flashes usually have a built-in reflector that is less customizable.nSync: Strobes require a sync cord or wireless trigger to fire, while on-camera flashes are triggered by the camera's built-in flash or hot shoe contacts.nVersatility: Strobes are more versatile and can be used in a wider range of shooting scenarios, such as studio setups or outdoor portraits. On-camera flashes are best suited for events or situations where mobility is important.
