Light in Photography
The quantity of light entering the camera effects the apature and depth of field. The more light entering the camera the lower apature you need for a higher depth of field and visa versa. Use low shutter sped for brighter light. Higher quality of light allows for a longer possible depth of field. The higher quanty of light allows for more contrast. Soft Light is spread out light, not direct on the subject. It comes from an indirect source that is usually difused by filters of some sort. It makes the subject more visual from more points than if you shined a direct light on it. Hard light is concentrated light that comes directly from the source to the subject. It comes from direct sources of light such as flash lights. Front light is good for front detail on the subject, but it can also create a flat effect in the photo. Side light is good for adding depth to the photo but is bad for showing detail in the photo. Back light can create a sillouette if there is more light comming from the back than the front. It is bad for front detail.
