There is a fundamental difference between diffuse light and direct light. In the diffuse light environment, there is no obvious light ratio, and the light does not have strong directivity. When shooting in this environment, the light of the subject is almost the same when shooting at any angle. Taking photos in a diffuse light environment, the light and shadow effects produced are relatively flat, and the object being photographed will not produce wonderful light and shadow effects due to the light; at the same time, the contrast of the picture is low. However, the exposure control is relatively easy at this time, and good exposure results can be obtained by using the matrix metering in the camera.seo agency
