How to write the photo shooting requirements?

1, photographers have a solid technical foundation, which is the most fundamental premise.

No matter how expensive the equipment is, there is no good design idea, shooting concept and dare to discover innovative head melon seeds. No matter how expensive the equipment is, it can only be called "a photo" at most.

2. Persistent patience.

Many good photos can't be taken by photographers who run past with cameras. Photographers need a long time to prepare, and even need to "know astronomy above and geography below" to capture that wonderful moment.

Do you know how long it takes to take such a photo of the orbit of a star?

The basic essentials for taking good photos are as follows:

First, hold the camera steady.

Holding the camera steady is the prerequisite for obtaining high-quality photos. At the moment of pressing the shutter, even a slight shaking will affect the clarity of the photo. The key to holding the camera is to master the correct posture of holding the camera, and be good at using stable and solid objects such as trees, walls and railings to support the hand holding the camera or make the body feel dependent. If possible, use a tripod to stabilize the camera and press the shutter with cable release (see Figure 2-4-3), especially when shooting with a slow shutter or a long focal length lens.

Secondly, select the appropriate autofocus area.

Modern cameras basically have autofocus function, but it is not foolproof in actual shooting: sometimes, the subject you are concerned about is blurred in the photos taken, while the other parts of the picture are clear. In this case, you should check whether the autofocus area is selected. In some cameras, the autofocus area is located in the center of the viewfinder screen, so the subject must be placed in the center of the viewfinder screen to achieve correct focusing. What should I do if the subject should not be arranged in the center of the picture from the perspective of composition? In order to solve this problem, many autofocus cameras are now equipped with focus locking devices. The operation method is: first place the subject in the center of the viewfinder screen to focus, and then press the focus lock key (usually half-press the shutter). As long as the camera does not change the shooting distance, no matter how to adjust the picture composition, the subject can be clearly imaged. Advanced single-lens reflex camera adopts multi-area autofocus, and the corresponding focus area can be selected according to the position of the subject.

Third, correct metering and accurate exposure.

In the process of taking pictures in the past, you may have had such an experience: press the shutter against the rosy clouds all over the sky, and all the photos you can take are pale, and you can't see the wonder and splendor of the clouds; I photographed the snowy mountain, but the snow in the photo is a kind of depressing gray. Why is this happening? The light metering system of the camera measures the light with light reflectivity of 18% to determine the exposure. Accurate exposure can be obtained when the photometric picture is dominated by medium gray tone.
