High speed camera photography related details
Photometry, usually for portrait shots, photometry is measured on the face or even more strictly on the eye. Measure the light using the middle key point or point, move the metering point in the viewing window picture to the face position, then move it to the correct composition after measuring the light, and then press the shutter. Since we usually use negative film for portrait shots, overexposing 0.3 to 1 grid of points during development gives better results, a neat formula that many photographers often talk about
2. Aperture For portrait shooting, the author uses a large aperture to obtain a shallow depth of field, which is more prominent when the proportion of subjects is not large. Another advantage of using a wide aperture is that the shutter speed will not fall below the safe limit when the weather is dark
3. Shutter speed What is the safe limit for shutter speed? This is a critical value. If the speed exceeds this limit, you can avoid blurring the picture due to handshakes and object movement. However, shutter safety limits vary from person to person. It depends on whether the subject is moving and how much.
