Close-up indoor shooting method with insufficient photographic light

First correct it. The larger the aperture, the shallower the depth of field.

When shooting still life indoors, it is best to choose a tripod to ensure the stability of the camera when the shutter is too slow. At this time, the use of large aperture is generally not to increase the shutter, but because shooting creativity needs to blur the background to highlight the subject.

If you must use a small aperture to ensure a large depth of field, and at the same time you must shoot by hand, you can choose to improve iso to improve the shutter as much as possible to prevent false shooting. However, it should be noted that the iso should not be too high, and each model of machine has an acceptable iso range. If it exceeds the range, the number of dry spots increases obviously and the image quality decreases obviously.
