How to adjust the shutter speed and aperture value of Nikon D90?
Nikon D90 aperture value adjustment method: press the shutter release button to activate exposure metering, rotate the auxiliary indicator, and select the required aperture value from the minimum and maximum values of the lens.
Extended data:
The aperture value is displayed on the top control panel, with f plus a number. The larger the F value, the smaller the aperture, the less the light input and the greater the depth of field. The smaller the f value, the larger the aperture, the more light entering and the smaller the depth of field. By adjusting the aperture value, we can adjust the blur degree of the clear object background.
The shutter speed value is displayed as a number to the right of the aperture value. If the shutter speed value is displayed as a pure number, it means the reciprocal of the number. If the shutter value shows a number with two dots in the upper right corner, it represents this number. The faster the shutter speed, the clearer the image of the moving object will appear on the negative. On the contrary, the slower the shutter speed, the more blurred the moving object will appear.
