1, take a close-up of something that is still very small, such as flowers, birds and insects;

When using Av files, the aperture should be below f5.6 and the focal length should be above 50. Try to shoot the blurred background within 1m!

Iso100 if the light is good; If the light is not good, iso is better within 400.

2, shoot people:

Basically, we use a larger aperture (within f5.6) and a focal length of more than 50 mm The shooting distance depends on the whole body, chest circumference and large photos, so the background is blurred and Av files are used!

Good light, iso 100, poor light, within iso400.

People in motion use chasing to express their sense of motion (see the shooting of moving objects below for details)!

Step 3 shoot:

For Av files, use an appropriate aperture, above f8, and the focal length is arbitrary, but generally the wide-angle end is distorted, so use it as appropriate.

4. Look at the night scene:

Install tripod, Av gear, custom white balance or incandescent lamp. Aperture above f8 and small aperture can make the light show starlight effect. Use the pre-lifting function of reflector to reduce the machine vibration caused by the lifting of reflector after pressing the shutter. Cover the viewfinder with a square cover on the strap to prevent stray light from entering from behind and affecting the image quality; Within iso200, let the exposure time be as long as possible, let some people who have no intention of walking disappear from the picture, leave no trace, and purify the scene!

For example, if you take a photo of a square, you can use a very small aperture of about f20, iso 100, so the exposure time will be very long, so the walking figure will not stay in the photo! The square will be clean!

5. Set off fireworks:

Using the cable release and B shutter, you can shoot the effect of multiple fireworks overlapping!

6, shoot running things:

Good lighting: Av files, aperture size should be handled properly; 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 a TV file. The shutter is about 1/30. When you press the shutter, the lens moves behind the object at a suitable speed, which will produce a very dynamic effect!

Poor lighting: only handle it as appropriate, plus the use of chasing!

7, shooting running water or fountain:

Using TV files, the shutter speed is about 1/50, and the satin effect can be taken. If you use the shutter too fast, the fountain will shoot discontinuous water droplets!

8. Portrait at night:

On the tripod, adjust the white balance, automatic or custom white balance; iso 100-400； Av file, aperture f8 or so, 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.

Av aperture priority skills:

1. Whatever you shoot, don't shoot with the maximum aperture unless you want to keep the safety shutter.

2. Please try to use the aperture of F8~F 1 1 when shooting scenery.

3. When shooting close-ups of people and still life, the maximum aperture can be reduced by 1~2.

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.

Photometric method:

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

2. Make good use of measurement methods (weighing measurement, point measurement, center key measurement ...) according to the subject matter you shoot.

3. If you are not sure about photometry, please use AE lock to expose the surrounding gray things before shooting.

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

EV is exposure compensation.

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.

Most small digital cameras adjust exposure compensation through menus.

In the process of digital camera shooting, if you press the half shutter, a picture similar to the final effect will be displayed on the LCD screen, and all focusing and exposure will start. The exposure at this time is the exposure of the final picture. If the picture is obviously bright or dark, it means that the automatic metering accuracy of the camera has a big deviation, and exposure compensation should be forced. But sometimes the brightness displayed during shooting is different from the actual shooting result. Digital camera can browse the picture immediately after shooting, and at this time, you can see the brightness of the shot picture more accurately, and there will be no discrepancy. If the shooting result is obviously bright or dark, it is necessary to shoot again and force exposure compensation.

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. According to different cameras, the compensation interval can be adjusted in units of 1/2(0.5) or 1/3(0.3).

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. There are high and low grades of cameras. If the grade is high, the measurement will be more accurate, and if the grade is low, the deviation will increase. If it is a traditional camera, the film tolerance is relatively large, and the exposure deviation will not be a big problem within a certain range, but the CCD tolerance of a digital camera is relatively small, and a slight exposure deviation may affect the overall effect.

In a word, the adjustment of exposure compensation is determined by experience and sensitivity to color. Users must compare the image quality, sharpness, reduction and noise under different exposure compensation in order to take the best photos.

note:

The aperture in the Canon manual refers to the F value. The larger the aperture, the greater the depth of field.

Generally speaking, the aperture refers to the aperture, which is inversely proportional to the f value. The larger the aperture, the smaller the depth of field.

Av aperture priority automatic exposure.

Television shutter priority automatic exposure

automatic exposure

auto-focusing

Af-s- should be the same as SAF, with single autofocus. In contrast, continuous autofocus.

MAF- monitor autofocus. This mode can shorten the time required for focusing. Before the shutter button is pressed halfway, the camera will adjust the focal length so that you can use the adjusted focal length for composition. When the shutter button is pressed halfway and the autofocus lock is completed, the focus will be locked.

EV- exposure value, this term is usually used for exposure compensation.

Equal sensitivity. Every difference in sensitivity is equivalent to the exposure value corresponding to the aperture or shutter.
