SLR camera photo parameters

Setting Skills of Eight Conventional Scene Parameters

1, still life

Flowers, birds and insects: use a gear, the aperture is preferably f5.6 or below, and the focal length is preferably above 50 mm Try to shoot within 1m, and the closer the better, of course, you can't cross the nearest focal length of the lens. This will blur the background! Iso100 if the light is good; If the light is not good, iso is better within 400.

2. Portrait

Basically, we use a larger aperture (for example, within F 1.8-f5.6), a focal length of more than 50 mm, and the shooting distance depends on the whole body, chest circumference and head shot, so the background is blurred. Use a file! Good light, iso 100, poor light, within iso400.

Shoot the scenery

First gear, use appropriate aperture, above f8, and the focal length is arbitrary, but generally the wide-angle end is distorted, so use it as appropriate.

On the tripod, use the flat cable to release, M-file, custom white balance or incandescent lamp, the aperture is above f8, and the small aperture can make the light shine like a star; Within iso200, making the exposure time as long as possible can make some people who have no intention of walking disappear from the picture, leaving no trace and purifying the scene.

By using the cable, B shutter and long exposure, the effect of overlapping multiple fireworks can be photographed.

In the case of good light: first gear, the aperture size should be treated as appropriate; A large depth of field effect can be obtained with an aperture above f8, and a shallow depth of field effect can be obtained with a small aperture.

If you want to shoot a very dynamic effect, you can use S file, shutter 1/30 or so. When you press the shutter when focusing, the lens will move behind the object at a proper speed, which will produce a very dynamic effect. The focus mode adopts artificial intelligence autofocus mode.

Poor lighting: only handle it as appropriate, plus use chasing light.

7. Take photos of waterfalls or fountains.

Using S-file, the shutter speed is about 1/50, you can shoot the effect of satin, and using a faster shutter, you can shoot the effect of water droplets!

8. The portrait was taken at night

On the tripod, adjust the white balance, automatic or custom white balance; iso 100-400； First gear, the aperture is around f8, adopting slow synchronous flash and Hou Lian flash mode; At this time, the flash will flash twice, press the shutter to flash once, and it will flash again before the exposure is over, so people should not leave before flashing twice. This can make the characters clear and the background neon beautiful, so that the background will not be underexposed or too dark.

9. Aperture priority skills:

Elementary photography tutorial: SLR setting optimization skills, shooting all reference parameters of 8 scenes.

1) No matter what you shoot, don't shoot with the maximum aperture as long as it doesn't affect the safety shutter.

2) Please try to use the aperture of F7-F 1 1 when shooting the scenery.

3) The maximum aperture can be reduced to 1-2, which is used for close-up of people and still life.

4) Please try to control the safety shutter above the reciprocal of the focal length. The wide-angle shutter should also be above 1/30 seconds. If the shutter is insufficient, please increase the aperture or ISO.

10. Photometric mode:

1) Don't point to the sky, don't point to the darkest place. Grab the middle value.

2) According to the subject matter you are shooting, make good use of metering modes (weighing metering, spot metering and central key metering).

3) If you are not sure about metering, please expose and lock the gray things around you before shooting.

4) Try not to measure light for white or black objects, otherwise please remember to subtract EV from black and add EV to white.

EV is exposure compensation, and exposure compensation is also an exposure control method, generally around 2-3EV. If the ambient light source is dark, you can increase the exposure value (such as+1EV, +2EV) to highlight the clarity of the picture.

When the shooting environment is dark and it is necessary to increase the brightness, and the flash can't work, exposure compensation can be carried out to increase the exposure appropriately. When making exposure compensation, if the photo is too dark, the EV value should be increased. Every time the EV value increases, it is 1.0, which is equivalent to doubling the light input. If the photo is too bright, the EV value should be reduced. Every time the EV value is reduced, it is equivalent to doubling the amount of light entering.

When the photographed white object looks gray or not white enough in the photo, it is necessary to increase the exposure, which simply means "the whiter the more". This seems to run counter to the basic principles and habits of exposure, but it is not. This is because the camera's photometry often focuses on the central subject, and the white subject will make the camera mistakenly think that the environment is very bright, so it is underexposed, which is also a common problem that most beginners are prone to make.

Because the shutter time or aperture size of the camera is limited, it is impossible to reach the adjustment range of 2EV all the time, so exposure compensation is not omnipotent, and it is still possible to underexpose in too dark environment. At this time, it is necessary to consider matching the flash or increasing the ISO sensitivity of the camera to improve the brightness of the picture. Generally speaking, the smaller the brightness contrast of the scene, the more accurate the exposure, otherwise the deviation will increase.
