continuous lighting and flash lighting

Continuous lighting is the opposite of flash – the lights are constantly lit instead of only when the shutter is pressed.

A Key light is the primary source of light in your images. The colour, strength and shape of your key light will affect the entire composition.

Backlighting involves having the main light source for a photograph behind the primary subject – this can create some interesting shadows and also eliminate ambiguity if the photographer wishes to.

 In photography terms, reflected light is light that reflects off the subject. This is most often what the camera records to make a photograph. Regardless of the light source, light is altered by whatever it reflects off. Rays of light reflect, or bounce off, objects just like a ball bounces on the ground. This reflection of light is what enables us to see everything around us. 

Flash lighting

Flash lighting involves the use of a bulb that flashes when the shutter is pressed. This creates a high key light source and eliminates shadows. It is also mostly paired with a fairly high shutter speed.
