A neutral gray card may be used to set exposure at a consistent level before placing the subject in the scene. 过高的对比度通常会导致整个 画面光影明显。可以通过对拍摄物的散射光 调节获取正确的对比度。这时的闪光会 在降低整体对比度的同时增加局部 的对比度。 Contrast that is too high is usually due to the overall light and shade in the scene. Correct contrast can be achieved by directing diffused lighting onto the subject. Such lighting increases the local contrast while reducing the total contrast. 照片质量受拍摄时使用的闪光类型的影响。应避免使用白 炽灯和荧光灯混 合在一起的闪光灯。使用正确的滤色镜可以提高整体闪光质量使传 统胶卷 或数码相机传感器感应到，从而抵消非自然色彩效果。某些高级数码相.
