How does Nikon SLR d3200 measure light?

1, photometry mainly refers to the scale table in the viewfinder to judge whether the exposure of the photo is appropriate. File A and file S are the matching of aperture or shutter by the machine according to the photometric value. Mainly when shooting different scenes, choose different metering modes and choose a reference point.

2. In the case of smooth light, the overall light difference of the picture is not obvious, and matrix photometry can achieve good results. However, the contrast between the background light and the shady place will be great because of the sunlight. At this time, you will use the central key metering or spot metering to get the metering value of the object you want to shoot, so that the sky will be overexposed and become very white, and the object you want to shoot can achieve better results.

To put it simply, you can choose which position you want to shoot as the metering point. Matrix photometry, central key photometry and point photometry are his ranging from large to small.

4. Landscape is measured by matrix, portrait is measured by central key point, and light contrast is measured by point. If the shooting range of the scene is large, use the whole photo to evaluate it; Portrait focuses on the expression of human face, so it takes the central area as a reference; If the contrast is large, choose the point you want to shoot.
