In the context of cameras developing in an increasingly intelligent direction, the function of autofocus is becoming more and more powerful, and many people are gradually "giving up" manual focus .
However, manual focus has its own inherent irreplaceable advantages. In some special photography scenes, manual focus is necessary and the most efficient.
So, when do you need to use manual focus?
1. Low-light environment
In a low-light environment, the camera cannot accurately perform automatic focus because the light reflected by the object into the camera is too weak. Even if the camera's own flash is used, is often out of focus .
However, manual focus will not occur. As long as you turn the focus ring and pay attention to the clarity of the viewfinder or screen, you can achieve accurate focus.
So in a low-light environment, if our camera no longer supports autofocus ('s focus response is particularly slow, the focus frame shows red, flash pops up by itself, etc. ), we can switch to manual focus mode. You can also illuminate the subject and focus it and make choices according to your personal needs.
2. The light contrast is strong
In scenes with particularly strong light contrast, such as backlight, stage and other environments, the camera's autofocus is also prone to inaccurate situations. We need to view the photos in time. If we find that the focus is inaccurate, we need to decisively switch to manual focus to avoid ruining all photos due to focus problems.
3. The shooting distance is too close and far
When the subject being photographed is too close or too far , it is best for us to use manual focus:
When shooting ultra-long-distance objects such as the moon, manual focus can focus more accurately;
When shooting objects at particularly close distances, automatic focus is prone to inconsistent focus and inaccurate focus. We also need to use manual focus to achieve accurate focus.
4. Solid color object
When the solid color account for too much solid color in shooting large areas of solid color objects or pictures, automatic focus will also occur in slow focus and cannot match the upper focus. Manual focus can avoid this situation well.
5. Planar
planar objects, especially objects that are perpendicular to the lens shooting direction and have no color, shape and other characteristics, can easily cause problems such as slow autofocus. If we are still using a large aperture, we need to pay more attention to using manual focus to ensure accuracy.
6. Complex scene
When there are too many elements in the picture, especially when there are many other elements near the subject or there are obvious foreground barriers in front of the subject, we try to choose manual focus to ensure that the focus point falls accurately on the subject.
You can zoom in and view it if necessary. Don’t just take a clear picture based on your feelings. Otherwise, when you view the photos later, you will find that sometimes a little bit of focus is inaccurate, which will cause the subject to blur into one.
That’s all for today’s content ~
