SLR shooting technique requirements: 1, large depth of field? 2. Small depth of field? 3. High speed shutter? 4. Low speed shutter?

1, large depth of field, keep enough depth of field clear, such as scenery, multi-person photos, etc. , use a small aperture.

2, the depth of field is small, the depth of field range is small, the theme is highlighted, the sense of space and depth is rendered, and the background is blurred, which has a "beautification" effect. Such as portraits, flowers, still life, etc. , use a large aperture.

3, high-speed shutter, used when shooting objects in motion, to ensure that the photos taken are clear.

4. Low-speed shutter. To use this shutter, you generally need experience and skills to take photos with strong movement, such as sports photography, waterfalls and light and shadow flow.

There are many aspects to these problems, and there are also contents that the photographer wants to express, which cannot be fully explained one by one, but only the main aspects.
