Digital cameras have many preset modes to choose from. These preset programs allow you to choose the right shutter speed and aperture to shoot. For a novice, these patterns are very useful. Not only that, in order to capture some fast shots, some professional photographers will also choose the preset mode. You need to understand and master the various modes in the camera, but remember that the preset modes of different cameras may be slightly different. The following are some of the most common:
I. Full automation
Shutter: 1/640s aperture: f/5.6 sensitivity: 100 flash: not turned on
& nbsp; & nbsp; & nbsp; & nbsp; full automatic exposure is set by the camera to choose the best shutter speed, aperture, sensitivity and flash. All you need to do is aim at the subject and press the shutter. If you don't know anything about photography and have to take it quickly, that's great. Under the condition of sufficient daylight, it can take very accurate exposure photos. But when the light is not uniform, the camera may unnecessarily turn on the flash.
II. Portrait Model
Shutter: 1/200s aperture: f/4 sensitivity: 200 flash: on
& nbsp; & nbsp; & nbsp; & nbsp; & portrait mode will "think" that it will take the subject in the picture foreground, choose a shallow depth of field to ensure that the focus on the characters while the background is blurred. If the camera considers the scene to be dark, it may force the flash. Forced flash is very useful when the sun is strong and shadows are deep. Portrait modes usually perform better when there is enough light.
3. Micro-Distance Model
Shutter: 1/200s aperture: f/3.2 sensitivity: 100 flash: on
& nbsp; & nbsp; & nbsp; & nbsp; macro mode is very useful for shooting objects smaller than your hand. Macro mode can't help you take big close-ups unless you use a macro lens. The macro mode is suitable for use in bright environments. It sets a shallow depth of field to focus on the object. Therefore, tripods should be used when the light is darker. You need to focus very carefully and accurately, because the macro mode usually has very shallow depth of field and can tolerate fewer errors.
4. Scenery Model
Windscape modes usually have smaller apertures (larger apertures) so that the image can be clearly imaged from the foreground to the infinite distance (in old cameras, "infinite distance" is represented by a symbol "_". Landscape mode is more suitable for wide-angle lens, but also suitable for use when the light is sufficient. The camera turns on the flash when it thinks the foreground is dim, but you can turn it off manually.
Figure shutter: 1/100s aperture: f/16 sensitivity: 100 flash: not turned on
V. Sports Model
Shutter: 1/750s aperture: f/9.5 sensitivity: 200 flash: not turned on
& nbsp; & nbsp; & nbsp; movement is a fast-paced activity, so the movement mode will choose a higher shutter speed, such as fixed-point 1/500s ~ 1/1000s. Higher shutter speeds can solidify momentary dynamics, which means there is no need to turn on the flash - this mode is also suitable for daytime. Motion mode works well with fast continuous shooting mode - you can capture a series of images of people in mid-air.
Sixth, Nightscape Portrait Model
Shutter: 1/5s aperture: f/4 sensitivity: 320 flash: on
& nbsp; & nbsp; & nbsp; & nbsp; in the night scene portrait mode, the camera tries to balance the relationship between the dark background and the exposure required by the foreground subject. In order to get a clear background, the aperture needs to be opened large enough to get enough light. But at the same time, it is necessary to turn on the flash to illuminate the person's face, so as to avoid blurring caused by the low-speed shutter. Some night scene portrait modes can flash twice to create unusual double exposure effects.
VII. Advanced Model
Most DSLRs also have several alphabetical modes - manual (M), aperture priority (Av), shutter priority (Tv or S) and program (P). Manual mode allows the photographer to set any parameters of the camera manually; the aperture priority mode is determined by the photographer, and the camera automatically sets the shutter speed; the shutter priority mode is set by the photographer (for example, when shooting a moving object), and then the camera automatically sets the aperture. The program exposure mode is somewhat similar to the automatic mode - the aperture and shutter are set by the camera, but the photographer can adjust shooting and image-recording functions by himself.
Some people think that only non-professionals will use the preset mode. In fact, sometimes if we are in a hurry to shoot, it is too late to manually adjust the parameters. Using different modes can teach you how to make the best settings in different situations. If you have doubts, you can also use automatic mode first, and then manually adjust. The automatic mode is used. Try to understand and familiarize yourself with each setting.
